WARNING!
A CAREFUL NAVIGATOR NEVER RELIES ON ONLY ONE METHOD
TO OBTAIN POSITION INFORMATION.
CAUTION
When showing navigation data to a position (waypoint), a GPS unit will show
the shortest, most direct path to the waypoint. It provides navigation data to the
waypoint regardless of obstructions. Therefore, the prudent navigator will not
only take advantage of all available navigation tools when traveling to a waypoint, but will also visually check to make sure a clear, safe path to the waypoint
is always available.
WARNING!
When a GPS unit is used in a vehicle, the vehicle operator is solely responsible for operating the vehicle in a safe manner. Vehicle operators
must maintain full surveillance of all pertinent driving, boating or flying conditions at all times. An accident or collision resulting in damage
to property, personal injury or death could occur if the operator of a
GPS-equipped vehicle fails to pay full attention to travel conditions and
vehicle operation while the vehicle is in motion.

Section 1: Read Me First!
How this manual can get you out on the road, fast!
Welcome to the exciting world of digital sonar and GPS! We know you
are anxious to begin navigating and finding fish, but we have a favor to
ask. Before you grab the unit and begin installing it, please give us a
moment or two to explain how our manual can help you get the best
performance from your compact, color display, combination fish finder
and mapping GPS receiver.
First, we want to thank you for buying a Eagle sonar/GPS unit.
Whether you are a first time user or a professional fisherman, you'll
discover that your unit is easy to use, yet capable of handling demanding navigation and sonar tasks. When you team your unit with our custom mapping software MapCreate 6, you have an incredible combination. You will not find another combination GPS and sonar unit with
this much power and this many features for this price!
Our goal for this book is to get you on the water fast, with a minimum
of fuss. Like you, we would rather spend more time boating or fishing
and less time reading the manual!
So, we designed our book so that you don't have to read the whole thing
from front to back for the information you want. At the start (or end) of
each segment, we'll tell you what content is coming up next. If it's a
concept you're already familiar with, we'll show you how and where to
skip ahead for the next important topic. We've also made it easy to look
up any tips you may need from time to time. Here's how:
The manual is organized into 10 sections. This first section is an introduction to the FishElite® 502c iGPS and SeaCharter® 502cDF iGPS. It
tells you the basics you need to know before you can make the unit look
around and tell you where you are or look below the surface to find
some fish.
Section 2 will help you install your unit and the transducer . We'll show
you how to get the MultiMedia Card (MMC) correctly installed inside
the unit. We'll also tell you about some of the available accessories.
Section 3 covers Basic Sonar Operation. It will show you how easy it is
to run your unit, right out of the box. This section features a one-page
Sonar Quick Reference. (If you've already jumped ahead and figured out how to install the unit yourself, and you just can't wait
any longer, turn to the Quick Reference on page 47 and head
for the water with your unit!)
1
After you have gained some experience with your sonar, you will want
to check out Section 4, which discusses more advanced Sonar Options
and Other Features.
When you come to a sonar menu command on the unit's screen, you can
look it up in the manual by skimming over the table of contents, just flipping through Section 3 or scanning through the sonar options in Section 4.
If you're having difficulty with your sonar, you can find an answer to
the most common problems in Section 5, Sonar Troubleshooting.
The manual switches from sonar to navigation in Section 6, which introduces you to Basic GPS Operations. This section features a onepage GPS Quick Reference on page 98.
Section 6 contains short, easy-to-scan GPS lessons that follow one another in chronological order. They're all you'll need to know to find your
way on the water quickly.
After you've learned the basics (or if you already have some GPS experience), you may want to try out some of the unit's many advanced
navigation features. That brings us to Section 7, Advanced GPS Operations. This section contains the rest of the unit's GPS command functions, organized in alphabetical order.
When you come to a GPS menu command on the screen, you can look it
up in the manual by skimming over the table of contents, just flipping
through Section 6 or scanning through the command portion of Section 7.
This unit is ready to use right out of the box, but you can fine tune and
customize it's operation with dozens of options. Since sonar is the unit's
key feature, we put the main sonar options in Section 4. Some options,
such as screen brightness settings, affect both sonar and GPS operations. We describe how to use those common options along with GPS
options in Section 8, System Setup and GPS Setup Options. Section 8 is
organized in alphabetical order.
In Section 9, we go into more detail on one of the unit's most remarkable
GPS capabilities — Searching. We'll introduce a search example in the Basic GPS Operation section, but there are so many map items you can
search for, we had to give this function it's own section in the manual! For
example, did you know this unit can look up business phone numbers,
functioning as a virtual Yellow Pages? We’ll show you how in Section 9.
Finally, in Section 10, we offer Supplemental Material, including a list
of the GPS datums used, warranties and customer service information.
Now, if you're into the fine details, glance over the next segment on
specifications to see how much sonar and GPS power your unit contains.

How Eagle Sonar Works
Sonar has been around since the 1940s, so if you already know how it
works, skip down to read about the relatively new technology of GPS.
But, if you've never owned a sonar fish finder, this segment will tell you
the under water basics.
Sonar is an abbreviation for SOund NAvigation and Ranging, a technology developed during World War II for tracking enemy submarines. A
sonar consists of a transmitter, transducer, receiver and display. Here's
how it locates the bottom and finds fish.
The transmitter emits an electrical impulse, which the transducer converts into a sound wave and sends into the water. (The sound frequency
can't be heard by humans or fish.) The sound wave strikes an object
(fish, structure, bottom) and bounces back to the transducer, which
converts the sound back into an electrical signal.
The receiver amplifies this return signal, or echo, and sends it to the
display, where an image of the object appears on the scrolling sonar
5
chart. The sonar's microprocessor calculates the time lapse between the
transmitted signal and echo return to determine the distance to the
object. The whole process repeats itself several times each second.
Your unit can record a log of the sonar signals that scroll across the
screen and save them to the MMC memory card. (These recordings are
also called sonar charts or sonar graphs.) You can replay this sonar log
in the unit using the Sonar Simulator function, or play it back on a personal computer using our free Sonar Viewer or product emulator. The
viewer and emulator are available for download from the Eagle web
site, www.eaglesonar.com.
You can save several different sonar log files, erase 'em and record new
ones, over and over again. The size of your sonar recordings is only
limited by the free space available on your MMC.
How GPS Works
You'll navigate faster and easier if you understand how the unit scans
the sky to tell you where you are on the earth – and where you're going.
(But if you already have a working understanding of GPS receivers and
the GPS navigation system, skip on ahead to Section 2, Installation &
Accessories on page 13. If you're new to GPS, read on.
Think of your unit as a small but powerful computer. The unit includes
a keypad and a screen with menus so you can tell it what to do. The
screen also lets the unit show your location on a moving map, as well as
point the way to your destination.
This gimbal-mounted unit uses an internal antenna and receiver,
which makes the system work like your car radio. But instead of your
favorite dance tunes, this receiver tunes in to a couple of dozen GPS
satellites circling the earth. (It will also listen to WAAS satellites in
orbit, but we will delve into that in the segment introducing you to GPS
and WAAS.)
Your unit listens to signals from as many satellites as it can see above
the horizon, eliminates the weakest signals, then computes its location
in relation to those satellites. Once the unit figures its latitude and longitude, it plots that position on the moving map shown on the screen.
The whole process takes place several times a second!
The performance doesn't stop there. Stored in the permanent memory
of each unit is a basic background map of the entire world. We lock it in
here at the factory — you can not change or erase this map.
The background map is suitable for many navigation chores, but for
maximum accuracy and much more detail, you need our optional map6
making software, MapCreate 6 or one of our special plug-and-play
mapping cards. Some unit features — such as searching for businesses
and addresses — won't work without a custom MapCreate map. There
is so much detail in our background map (and even more in MapCreate)
that we'll describe their contents and differences in Section 3, Basic
GPS Operations, on page 93.
Another portion of the unit’s onboard memory is devoted to recording GPS
navigation information, which includes waypoints, event marker icons,
trails and routes. This lets you look back the way you came. Think of this
data storage like the hard drive memory in a computer or a tape in a cassette tape recorder. You can save several different GPS data files, erase
'em and record new ones, over and over again. Like any computer file,
these GPS Data Files (file format *.usr) can be shared between Eagle
GPS or sonar/GPS units or even personal computers.
This unit has one more thing in common with a personal computer. Just
as computers have a floppy disk drive for storing and exchanging files,
the unit has a slot for an MMC (MultiMedia Card) or SD card (Secure
Digital card) flash memory card. These solid-state memory devices are
about the size of a postage stamp, but can hold data ranging from 8 MB
to 1 GB in size. (Compare that to a floppy disk's 1.44 MB capacity!) This
unit uses all that MMC space for two key GPS purposes.
You can backup your onboard GPS Data Files by copying them to the
MMC. Since the MMC is removable (like a floppy disk or a cassette tape),
you can store these GPS Data Files on a personal computer equipped with
an MMC card reader. (Or store them on a pocketful of MMCs, if you don't
have a computer.) Our MapCreate mapping software can save, edit or
create its own GPS Data Files, which can be copied to the MMC and then
loaded from the MMC into the unit's memory. (NOTE: No matter where
they come from, GPS Data Files must be loaded from the MMC into memory before the unit can use them.)
The other key GPS use for MMCs is storage of special high-detail, custom maps, which you can produce on your computer with our MapCreate software. These MapCreate custom maps contain much greater detail than the basic background map. These Custom Map Files (file
format *.lcm) can also be shared between Eagle GPS or sonar/GPS
units and personal computers. This unit automatically reads Custom
Map Files directly from the MMC or SD card. To use a custom map, all
you need to do is slide an MMC containing a map into the unit.
Introduction to GPS and WAAS
Well, now you know the basics of how your unit does its work. You
might be ready to jump ahead to Section 2, Installation & Accessories,
7
so you can mount your unit and plug in the power. Or you might want
to see how our text formatting makes the manual tutorials easy to
skim. If that's the case, move on to How to Use This Manual on page
11. But, if you want to understand the current state of satellite navigation, look over this segment describing how GPS and its new companion
WAAS work together to get you where you're going.
The Global Positioning System (GPS) was launched July 17, 1995 by
the United States Department of Defense. It was designed as a 24hour-a-day, 365-days-a-year, all weather global navigation system for
the armed forces of the U.S. and its allies. Civilian use was also available at first, but it was less accurate because the military scrambled
the signal somewhat, using a process called Selective Availability (SA).
GPS proved so useful for civilian navigation that the federal government discontinued SA on May 2, 2000, after the military developed
other methods to deny GPS service to enemy forces. Reliable accuracy
for civilian users jumped from 100 meters (330 feet) under SA to the
present level of 10 to 20 meters (about 30 to 60 feet.)
Twenty-four satellites orbit 10,900 nautical miles above the Earth, passing
overhead twice daily. A series of ground stations (with precisely surveyed
locations) controls the satellites and monitors their exact locations in the
sky. Each satellite broadcasts a low-power signal that identifies the satellite and its position above the earth. Three of these satellites are spares,
unused until needed. The rest virtually guarantee that at least four satellites are in view nearly anywhere on Earth at all times.
A minimum of three satellites are required to determine a 2D fix.
The system requires signal reception from three satellites in order to
determine a position. This is called a 2D fix. It takes four satellites to
determine both position and elevation (your height above sea level —
also called altitude). This is called a 3D fix.
8
Remember, the unit must have a clear view of the satellites in order to
receive their signals. Unlike radio or television signals, GPS works at
very high frequencies. These signals can be easily blocked by trees,
buildings, an automobile roof, even your body.
Like most GPS receivers, this unit does not have a compass or any
other navigation aid built inside. It relies solely on the signals from the
satellites to calculate a position. Speed, direction of travel and distance
are all calculated from position information. Therefore, in order for unit
to determine direction of travel, you must be moving and the faster, the
better. This is not to say that it won’t work at walking or trolling
speeds — it will. There will be more wandering of the data shown on
the display.
GPS alone is accurate for route navigation, but the U.S. Federal Aviation Administration has special aircraft navigation needs that go beyond basic GPS. Consequently, the FAA has developed a program to
boost GPS performance with its Wide Area Augmentation System
(WAAS). The FAA commissioned the system on July 11, 2003.
WAAS is designed to increase GPS accuracy to within 7.6 meters vertically and horizontally, but according to the FAA, it consistently comes
within 1-2 meters horizontally and 2-3 meters vertically. It does this by
broadcasting correction signals on GPS frequencies. Your unit automatically receives both GPS and WAAS signals.
There are, however, some fringe areas of the U.S., including parts of
Alaska, that do not yet receive robust WAAS coverage. Continued
WAAS development is planned to extend WAAS coverage in the years
to come.
WAAS boosts the accuracy of land GPS navigation, but the system is
designed for aircraft. The satellites are in a fixed orbit around the
Equator, so they appear very low in the sky to someone on the ground
in North America. Aircraft and vessels on open water can get consistently good WAAS reception, but terrain, foliage or even large manmade structures can sometimes block the WAAS signal from receivers.
You'll find that using your GPS receiver is both easy and amazingly
accurate. It’s easily the most accurate method of electronic navigation
available to the general public today. Remember that this receiver is
only a tool. Always have another method of navigation available, such
as a map or chart and a compass.
Also remember that this unit will always show navigation information
in the shortest line from your present position to a waypoint, regardless
of terrain! It only calculates position, it can’t know what’s between you
9
and your destination, for example. It’s up to you to safely navigate
around obstacles, no matter how you’re using this product.

How to use this manual: typographical conventions
Many instructions are listed as numbered steps. The keypad and arrow
"keystrokes" appear as boldface type. So, if you're in a real hurry (or
just need a reminder), you can skim the instructions and pick out what
menu command to use by finding the boldface command text. The following paragraphs explain how to interpret the text formatting for
those commands and other instructions:
Arrow Keys
The arrow keys control the movement of dotted cross-hair lines on your
mapping screen called the cursor. The arrow keys also control a horizontal line depth cursor on the sonar screen. The arrow keys help you
move around the menus so you can execute different commands. They
are represented by symbols like these, which denote the down arrow
key, the up arrow, the left arrow and the right arrow: ↓ ↑ ← →.
Keyboard
The other keys perform a variety of functions. When the text refers to a
key to press, the key is shown in bold, sans serif type. For example, the
"Enter/Icons" key is shown as ENT and the "Menu" key is shown as MENU.
Menu Commands
A menu command or a menu option will appear in small capital letters, in
a bold sans serif type like this: ROUTE PLANNING. These indicate that you are
to select this command or option from a menu or take an action of some
kind with the menu item. Text that you may need to enter or file names
you need to select are show in italic type, such as trail name.
Instructions = Menu Sequences
Most functions you perform with the unit are described as a sequence of
key strokes and selecting menu commands. We've written them in a
condensed manner for quick and easy reading.
For example, instructions for navigating a trail would look like this:
1. From the Map Page, press MENU|MENU|↓ to MY TRAILS|ENT.
2. Press ↓ to Trail 1|ENT|→ to NAVIGATE|ENT.
3. You are asked to wait while it converts the trail into a route.
11
4. The wait message disappears and the unit begins showing
navigation information along the trail. Now, begin moving and
follow your unit's directions.
Translated into complete English, step 1 above would mean: "Start on
the Map Page. Press the Menu key twice. Next, repeatedly press (or
press and hold) the down arrow key to scroll down the menu and select
(highlight) the My Trails menu command. Finally, press the Enter key."
Step 2 would mean: "Press the down arrow key repeatedly to scroll to
the trail named Trail 1, and press Enter. Next, press the right arrow
key to highlight the Navigate command, then press Enter."

Section 2: Installation & Accessories
Preparations
You can install the unit in some other order if you prefer, but we recommend this installation sequence:
Caution:
You should read over this entire installation section before drilling any holes in your vessel!
1. Determine the approximate location for the unit, so you can plan how
and where to route the cables for the transducer, any sensor and power.
This will help you make sure you have enough cable length for the desired configuration.
NOTE:
The GPS antenna is inside the unit, so you must mount the unit in
a location with an unobstructed view of the sky.
2. Determine the approximate location for the transducer, any sensor
and their cable routes.
3. Determine the location of your battery or other power connection,
along with the power cable route.
4. Install the transducer and route the transducer cable to the sonar
unit. Install the speed or temp sensor, if applicable, and route the cable
to the unit.
5. Route the power cable from the unit's location to an appropriate
power source and connect it there.
6. Connect the transducer/power cable (and any sensor cables) to the
unit and mount the unit on the bracket.
Transducer Installation
These instructions will help you install your Skimmer transducer on a
transom, on a trolling motor or inside a hull. These instructions cover
both single- and dual-frequency Skimmer transducers. Please read all
instructions before proceeding with any installation.
Your Skimmer transducer typically comes packaged with a one-piece
stainless steel bracket for mounting it to the transom of your boat. The
optional trolling motor mount uses a one-piece plastic bracket with an
adjustable strap. These are kick-up mounting brackets. They help prevent damage if the transducer strikes an object while the boat is moving. If the transducer does kick-up, the bracket can easily be pushed
back into place without tools.
13
Read these instructions carefully before attempting the installation.
Determine which of the installation methods is right for your boat.
Remember, transducer location is the most critical part of a sonar installation.
Recommended Tools and Supplies
If you prefer the option of routing the cable through the transom, you
will need a 5/8" drill bit. (If you intend to install an additional speed or
temp sensor and route its cable through the same hole in the transom,
you will need a 1" (25.4 mm) drill bit to accommodate all the cables.)
NOTE:
The following installation types also call for these recommended
tools and required supplies that you must provide (supplies listed
here are not included):
Single-frequency transom installations
Tools include: two adjustable wrenches, drill, #29 (0.136") drill bit, flathead screwdriver. Supplies: none.
Dual-frequency transom installations
Tools: two adjustable wrenches, drill, #20 (0.161") drill bit, flat-head
screwdriver. Supplies: four, 1" long, #12 stainless steel slotted wood
screws.
Single-frequency trolling motor installations
Tools: two adjustable wrenches, flat-head screwdriver. Supplies: plastic
cable ties.
Shoot-through hull installations
Tools: these will vary depending on your hull's composition. Consult
your boat dealer or manufacturer. Other tools are a wooden craft stick
or similar tool for stirring and applying epoxy, and a paper plate or
piece of cardboard to mix the epoxy on. Supplies: rubbing alcohol, 100
grit sandpaper, specially formulated epoxy adhesive available from LEI
(see ordering information on the inside portion of the back cover). A
sandwich hull also requires polyester resin.
Selecting a Transducer Location
1. The location must be in the water at all times, at all operating speeds.
2. The transducer must be placed in a location that has a smooth flow of
water at all times. If the transducer is not placed in a smooth flow of
water, interference caused by bubbles and turbulence will show on the
sonar's display in the form of random lines or dots whenever the boat is
moving.
14
NOTE:
Some aluminum boats with strakes or ribs on the outside of the
hull create large amounts of turbulence at high speed. These boats
typically have large outboard motors capable of propelling the boat
at speeds faster than 35 mph. Typically, a good transom location on
aluminum boats is between the ribs closest to the engine.
3. The transducer should be installed with its face pointing straight
down, if possible. For shoot-thru applications: Many popular fishing
boat hulls have a flat keel pad that offers a good mounting surface. On
vee hulls, try to place the transducer where the deadrise is 10° or less.
Deadrise less than 10°
Strakes
Pad
Vee pad hull (left); Vee hull (right). A pod style transducer is shown
here, but the principle is the same for Skimmers inside a hull.
4. If the transducer is mounted on the transom, make sure it doesn't
interfere with the trailer or hauling of the boat. Also, don't mount it
closer than approximately one foot from the engine's lower unit. This
will prevent cavitation (bubble) interference with propeller operation.
5. If possible, route the transducer cable away from other wiring on the
boat. Electrical noise from engine wiring, bilge pumps and aerators can
be displayed on the sonar's screen. Use caution when routing the transducer cable around these wires.
CAUTION: Clamp the transducer cable to transom near
the transducer. This will help
prevent the transducer from
entering the boat if it is
knocked off at high speed.

centerline
Hull bottom
Hull bottom
Align transducer centerline with hull bottom. A dual frequency
transducer (left) and a single frequency transducer (right).
How low should you go?
For most situations, you should install your Skimmer transducer so
that its centerline is level with the bottom of the boat hull.
This will usually give you the best combination of smooth water flow
and protection from bangs and bumps.There, however, are times when
you may need to adjust the transducer slightly higher or lower. (The
slots in the mounting brackets allow you to loosen the screws and slide
the transducer up or down.) If you frequently lose bottom signal lock
while running at high speed, the transducer may be coming out of the
water as you cross waves or wakes. Move the transducer a little lower
to help prevent this.
If you cruise or fish around lots of structure and cover, your transducer
may be frequently kicking up from object strikes. If you wish, you may
move the transducer a little higher for more protection.
There are two extremes you should avoid. Never let the edge of the
mounting bracket extend below the bottom of the hull. Never let the
bottom – the face – of the transducer rise above the bottom of the hull.
Shoot-Thru-Hull vs. Transom Mounting
In a shoot-thru-hull installation, the transducer is bonded to the inside
of the hull with epoxy. The sonar "ping" signal passes through the hull
and into the water. This differs from a bolt-thru-hull installation (often
called "thru-hull"). In that case, a hole is cut in the hull and a specially
designed transducer is mounted through the hull with a threaded shaft
and nut. This puts the transducer in contact with the water.
Typically, shoot-thru-hull installations give excellent high speed operation and good to excellent depth capability. There is no possibility of
transducer damage from floating objects, as there is with a transommounted transducer. A transducer mounted inside the hull can't be
knocked off when docking or loading on a trailer.
16
The shoot-thru-hull installation does have its drawbacks. First, some
loss of sensitivity does occur, even on the best hulls. This varies from
hull to hull, even from different installations on the same hull. This is
caused by differences in hull lay-up and construction.
Second, the transducer angle cannot be adjusted for the best fish arches
on your sonar display. (This is not an issue for flasher-style sonars.)
Lack of angle adjustment can be particularly troublesome on hulls that
sit with the bow high when at rest or at slow trolling speeds.
Third, a transducer CAN NOT shoot through wood and metal hulls.
Those hulls require either a transom mount or a thru-hull installation.
Fourth, if your Skimmer transducer has a built in temp sensor, it will
only show the temperature of the bilge, not the water surface temp.
Follow the testing procedures listed in the shoot-thru-hull installation
section at the end of this instruction booklet to determine if you can
satisfactorily shoot through the hull.
Transom Transducer Assembly and Mounting
The best way to install these transducers is to loosely assemble all of
the parts first, place the transducer's bracket against the transom and
see if you can move the transducer so that it's parallel with the ground.
The following instructions sometimes vary depending on the mounting
bracket that came with your transducer. Single frequency Skimmers
come with a one-piece stainless steel bracket, while dual frequency
Skimmers come with a two-piece plastic mounting bracket. Use the set
of instructions that fits your model.
1. Assembling the bracket.
A. One-piece bracket: Press the two small plastic ratchets into the sides
of the metal bracket as shown in the following illustration. Notice there are
letters molded into each ratchet. Place each ratchet into the bracket with
the letter "A" aligned with the dot stamped into the metal bracket. This
position sets the transducer's coarse angle adjustment for a 14° transom.
Most outboard and stern-drive transoms have a 14° angle.
17
Dot
Align plastic ratchets in bracket.
B. Two-piece bracket: Locate the four plastic ratchets in the transducer's hardware package. Press two ratchets into the sides of the plastic
bracket and two on either side of the transducer as shown in the following illustrations. Notice there are letters molded into each ratchet. Place
the ratchets into the bracket with the letter "A" aligned with the alignment mark molded into the bracket. Place the ratchets onto the transducer with the letter "A" aligned with the 12 o'clock position on the
transducer stem. These positions set the transducer's coarse angle adjustment for a 14° transom. Most outboard and stern-drive transoms
have a 14° angle.

2. Aligning the transducer on the transom.
A. One-piece bracket: Slide the transducer between the two ratchets. Temporarily slide the bolt though the transducer assembly and
hold it against the transom. Looking at the transducer from the side,
check to see if it will adjust so that its face is parallel to the ground.
If it does, then the "A" position is correct for your hull.
If the transducer's face isn't parallel with the ground, remove the
transducer and ratchets from the bracket. Place the ratchets into the
holes in the bracket with the letter "B" aligned with the dot stamped
in the bracket.
Reassemble the transducer and bracket and place them against the
transom. Again, check to see if you can move the transducer so it's parallel with the ground. If you can, then go to step 3A. If it doesn't, repeat
step 2A, but use a different alignment letter until you can place the
transducer on the transom correctly.

Insert bolt and check transducer position on transom.
B. Two-piece bracket: Assemble the transducer and bracket as
shown in the following figure. Temporarily slide the bolt though the
transducer assembly but don't tighten the nut at this time. Hold the
assembled transducer and bracket against the transom. Looking at the
transducer from the side, check to see if it will adjust so that its face is
parallel to the ground. If it does, then the "A" positions are correct for
your hull.

bracket holes with the letter "B" aligned with the bracket alignment
mark. Place them on the transducer aligned with the 12 o'clock position on the transducer stem.
Reassemble the transducer and bracket and place them against the
transom. Again, check to see if you can move the transducer so it's parallel with the ground. If you can, then go to step 3B. If it doesn't, repeat
step 2B, but use a different alignment letter until you can place the
transducer on the transom correctly.
3. Assembling the transducer.
A. One-piece bracket: Once you determine the correct position for the
ratchets, assemble the transducer as shown in the following figure.
Don't tighten the lock nut at this time.

Don't tighten the lock nut at this time.
4. Drilling mounting holes.
Hold the transducer and bracket assembly against the transom. The
transducer should be roughly parallel to the ground. The transducer's centerline should be in line with the bottom of the hull. Don't
let the bracket extend below the hull!
Mark the center of each slot for the mounting screw pilot holes. You
will drill one hole in the center of each slot.
Drill the holes. For the one-piece bracket, use the #29 bit (for the #10
screws). For the two-piece bracket, use the #20 bit (for the #12
screws).

5. Attaching transducer to transom.
A. One-piece bracket: Remove the transducer from the bracket and reassemble it with the cable passing through the bracket over the bolt as
shown in the following figures.
For single-frequency Skimmer, route cable over bolt and through
bracket. Side view shown (left) and seen from above (right).
Both bracket types: Attach the transducer to the transom. Slide the
transducer up or down until it's aligned properly with the bottom of the
hull as shown in the preceding and following figures. Tighten the
bracket's mounting screws, sealing them with the sealant.
Adjust the transducer so that it's parallel to the ground and tighten the
nut until it touches the outer washer, then add 1/4 turn. Don't over
tighten the lock nut! If you do, the transducer won't "kick-up" if it
strikes an object in the water.

6. Route the transducer cable through or over the transom to the sonar
unit. Make sure to leave some slack in the cable at the transducer. If
possible, route the transducer cable away from other wiring on the boat.
Electrical noise from the engine's wiring, bilge pumps, VHF radio wires
and cables, and aerators can be picked up by the sonar. Use caution
when routing the transducer cable around these wires.
WARNING:
Clamp the transducer cable to the transom close to the
transducer. This can prevent the transducer from entering the boat if it is knocked off at high speed.
If you need to drill a hole in the transom to pass the connector through,
the required hole size will be 5/8".
Caution:
If you drill a hole in the transom for the cable, make sure it is located above the waterline. After installation, be sure to seal the
hole with the same marine grade above- or below-waterline sealant used for the mounting screws.
7. Make a test run to determine the results. If the bottom is lost at
high speed, or if noise appears on the display, try sliding the transducer
bracket down. This puts the transducer deeper into the water, hopefully below the turbulence causing the noise. Don't allow the transducer
bracket to go below the bottom of the hull!
Trolling Motor Bracket Installation
(single-frequency only)
1. Attach the optional TMB-S bracket to the transducer as shown in the
following figure, using the hardware supplied with the transducer.
(Note: The internal tooth washer is supplied with the TMB-S.)

2. Slide the adjustable strap supplied with the TMB-S through the slot
in the transducer bracket and wrap it around the trolling motor. Position the transducer to aim straight down when the motor is in the water. Tighten the strap securely.
22
3. Route the transducer cable alongside the trolling motor shaft. Use
plastic ties (not included) to attach the transducer cable to the trolling
motor shaft. Make sure there is enough slack in the cable for the motor
to turn freely. Route the cable to the sonar unit and the transducer is
ready for use.

Transducer Orientation and Fish Arches
If you do not get good fish arches on your display, it could be because
the transducer is not parallel with the ground when the boat is at rest
in the water or at slow trolling speeds. If the arch slopes up – but not
back down – then the front of the transducer is too high and needs to be
lowered. If only the back half of the arch is printed, then the nose of the
transducer is angled too far down and needs to be raised.

NOTE:
Periodically wash the transducer's face with soap and water to remove any oil film. Oil and dirt on the face will reduce the sensitivity
or may even prevent operation.
Shoot-Thru-Hull Preparation
Hulls With Flotation Materials
The transducer installation inside a fiberglass hull must be in an area
that does not have air bubbles in the resin or separated fiberglass layers. The sonar signal must pass through solid fiberglass. A successful
transducer installation can be made on hulls with flotation materials
(such as plywood, balsa wood or foam) between layers of fiberglass if
the material is removed from the chosen area. See the figure below.
WARNING:
Do not remove any material from your inner hull unless
you know the hull's composition. Careless grinding or
cutting on your hull can result in damage that could sink
your boat. Contact your boat dealer or manufacturer to
confirm your hull specifications.
Fill with resin

Inner hull
Epoxy to hull first
Outer hull
Epoxy the transducer to a solid portion of the hull.
For example, some (but not all) manufacturers use a layer of fiberglass,
then a core of balsa wood, finishing with an outer layer of fiberglass.
Removing the inner layer of fiberglass and the balsa wood core exposes
the outer layer of fiberglass. The transducer can then be epoxied directly
to the outer layer of fiberglass. After the epoxy cures for 24 hours, fill the
remaining space with polyester resin. When the job is finished, the hull
is watertight and structurally sound. Remember, the sonar signal must
pass through solid fiberglass. Any air bubbles in the fiberglass or the
epoxy will reduce or eliminate the sonar signals.
Testing Determines Best Location
Ideally, the shoot-thru transducer should be installed as close to the
transom as possible, close to the centerline. This will give you the best
performance during high speed maneuvers.

Shoot-thru-hull transducer locations for
high speed or trolling speed operation.
To choose the proper location for shoot-thru-hull mounting, follow these
testing procedures: (You may need a helper to complete these steps.)
1. Anchor the boat in about 30 feet of water. Add a little water to the
sump of the boat. Plug the transducer into the sonar unit, turn it on, then
hold the transducer over the side of the boat in the water. Adjust the sensitivity and range controls until a second bottom echo is seen on the display. (You'll need to turn off Auto Sensitivity, Auto Depth Range and
ASP. Try a range setting that is two to three times the water depth. The
harder (more rocky) the bottom, the easier it will be to get a second bottom signal.) Don't touch the controls once they've been set.
True bottom
Second bottom
Manual range setting
Example of a second bottom signal. Unit is in 30 feet of water with
range set at 80 feet and sensitivity set at 87 percent.
2. Next, take the transducer out of the water and place it in the water
in the sump of the boat, face down. (The transducer face is shown in the
figure on the following page.) Notice how the signal strength decreases.
25
The second bottom signal will probably disappear and the bottom signal
intensity will likely decrease.
3. Now move the transducer around to find the best location with the
strongest possible bottom signal. If you find a spot with an acceptable
bottom signal, mark the location and move on to step 4.
If you can't get an acceptable bottom signal, try turning up the sensitivity
by three or five keystrokes and then move the transducer around once
more. If you find a spot that works, mark it and move on to step 4.
If you have to turn up sensitivity by more than five keystrokes to get a
good signal, the transducer should be mounted on the outside of the
hull. This is especially true if you have to turn sensitivity all the way
up to get a decent bottom signal.
4. Most people can get good results by following steps 1 through 3, so this
step is optional. If you want to make an extra effort to be absolutely sure
that your selected location will work under all conditions, make a test run
with the boat on plane and observe the bottom signal.
You'll need to figure some way to prop the transducer into position while
you make your test run. (A brick or two might be sufficient to hold it in
place.)
5. When you're satisfied with a location, mark it and proceed with the
installation.
Shoot-Thru-Hull Installation
If you are installing the transducer on a hull with floatation material
sandwiched within the hull, refer to the text "Hulls With Flotation Materials" beginning on page 24.
1. Make sure the area is clean, dry and free of oil or grease, then sand
both the inside surface of the hull and the face of the transducer with
100 grit sandpaper. The sanded hull area should be about 1-1/2 times
the diameter of the transducer. The surface of the hull must be flat so
the entire transducer face is in contact with the hull prior to bonding.
After sanding, clean the hull and transducer with rubbing alcohol to
remove any sanding debris.

WARNING:
Use only the epoxy available from LEI. It has been formulated to work with these installation procedures.
Other epoxy types may be too thin or may not cure to the
right consistency for optimum transducer performance.
2. The epoxy consists of the epoxy itself and a hardener. Remove the
two compounds from the package and place them on the paper plate.
Thoroughly stir the two compounds together until the mixture has a
uniform color and consistency. Do not mix too fast or bubbles will form
in the epoxy. After mixing, you have 20 minutes to complete the installation before the epoxy becomes unworkable.
Spread a thin layer of epoxy (about 1/16" or 1.5 mm thick) on the face of
the transducer as shown in the previous figure. Make sure there are no
air pockets in the epoxy layer! Then, apply the remaining epoxy to the
sanded area on the hull.
3. Press the transducer into the epoxy, twisting and turning it to force
any air bubbles out from under the transducer face. Stop pressing when
you bottom out on the hull. When you're finished, the face of the transducer should be parallel with the hull, with a minimum amount of epoxy between the hull and transducer.
4. Apply a weight, such as a brick, to hold the transducer in place while
the epoxy cures. Be careful not to bump the transducer while the epoxy
is wet.
27
Leave the weight in place for a minimum of three hours. Allow the epoxy to cure for 24 hours before moving the boat.
5. After the epoxy has cured, route the cable to the sonar unit and it's
ready to use.
Speed/Temperature Sensors
This unit can accept as many as two temperature sensors, which can be
used to monitor the temperature of surface water, a live well or some
other location. These units can also accept an optional speed sensor for
showing speed and distance traveled. However, you can only use one accessory at a time. If you would like to use a speed sensor and a second
temperature sensor at the same time, you will need a combination device.
NOTE:
This unit is packed with a transducer containing a built-in temp sensor.
The SeaCharter package also includes a speed sensor. If you have a
FishElite 502c and want a speed sensor or additional temp sensor, see
the Accessory Ordering Information in the back of this manual.
If a second temp sensor is used, it must be the model TS-2U. This
model has a fixed electronic address which designates it as the second
of two temp sensors. Dual temperatures are only displayed on the Full
Chart page. The Large Digital page will only display the primary temperature sensor. See the following wiring diagram for temperature and
speed sensor combinations.

Optional Speed Sensor Installation
All the units in this series can display speed and distance traveled, but
only the SeaCharter 502cDF iGPS comes packed with a speed sensor. If
you wish to purchase an optional additional sensor for your unit, refer
to the accessory ordering information inside the back cover of this
manual. The following instructions describe how to install the speed
sensor.
Recommended tools for this job include: drill, 5/8" drill bit, 1/8" drill bit for
pilot holes, screwdriver. Required supplies for this job include: four #8
stainless steel wood screws (3/4" long), high quality, marine grade aboveor below-waterline sealant.
First find a location on the boat's transom where the water flow is smoothest. Don't mount the sensor behind strakes or ribs. These will disturb the
water flow to the speed sensor. Make sure the sensor will remain in the
water when the boat is on plane.
29
Make sure the location does not interfere with the boat's trailer. Usually,
the sensor is mounted about one foot to the side of the transom's centerline.
Once you have determined the proper location for the unit, place the
sensor on the transom. The bottom of the bracket should be flush with
the hull's bottom. Using the sensor as a template, mark the hull for the
screw's pilot holes. Drill four 1/8" holes, one in each end of the slots.
Mount the sensor to the hull using #8 stainless steel wood screws (not
included). Use a high quality, marine grade above- or below-waterline
sealant to seal the screws. Make sure the sensor is flush with the bottom of the hull and tighten the screws.
Good location

Route the sensor's cable through or over the transom to the sonar unit.
If you need to drill a hole in the transom to pass the connector through,
the required hole size is 5/8".
Caution:
If you drill a hole in the transom for the cable, make sure it is located above the waterline. After installation, be sure to seal the
hole with the same marine grade above- or below-waterline sealant used for the screws.
30
The sensor is now ready for use. Connect the sensor to the accessory
socket on the back of your unit. If you have any questions concerning
the installation of the sensor, please contact your local boat dealer.
Power Connections
The unit works from a 12-volt battery system. For the best results, attach the power cable directly to the battery. You can attach the power
cable to an accessory or power buss, however you may have problems
with electrical interference. Therefore, it's safer to go ahead and attach
the power cable directly to the battery.
Caution:
When using the unit in a saltwater environment, we strongly recommend that you shut off the power supply to the power cable when
the unit is not in use. When the unit is turned off but still connected
to a power supply, electrolysis can occur in the power cable plug.
This may result in corrosion of the plug body along with the electrical contacts in the cable and the unit's power socket.
In saltwater environments we recommend you connect the power
cable to the auxiliary power switch included in most boat designs.
If that results in electrical interference, or if such a switch is not
available, we recommend connecting direct to the battery and installing an inline switch. This will let you shut off power to the
power cable when the unit is not in use. When you are not using
the unit, you should always shut off power to the power cable, especially when the power cable is disconnected from the unit.
If possible, keep the power cable away from other boat wiring, especially the engine's wires. This will provide the best isolation from electrical noise. If the cable is not long enough, splice #18 gauge wire onto
it. The power cable has two wires, red and black. Red is the positive
lead, black is negative or ground. Make sure to attach the in-line fuse
holder to the red lead as close to the power source as possible.
For example, if you have to extend the power cable to the battery or
power buss, attach one end of the fuse holder directly to the battery or
power buss. This will protect both the unit and the power cable in the
event of a short. It uses a 3-amp fuse.

WARNING:
This product must be independently fused with the enclosed 3-amp fuse (or equivalent), even if you connect to
a fused accessory or power buss.
If a malfunction happens inside the unit, extensive damage can occur if the enclosed fuse is not used. As with all
electrical devices, this unit could be damaged to a point
that it is unrepairable and could even cause harm to the
user when not properly fused.
CAUTION:
Failure to use the enclosed 3-amp fuse will void your warranty! For
a replacement, use a type 3AG 3-amp fuse.
This unit has reverse polarity protection. No damage will occur if the
power wires are reversed. However, the unit will not work until the
wires are attached correctly.
GPS Internal Antenna
The unit has a built-in 12-parallel channel GPS + WAAS antenna.
NMEA Cable Connections
NMEAis a standard communications format for marine electronic
equipment. For example, an autopilot can connect to the NMEA interface on the unit and receive positioning information. The unit is capable
of exchanging information with any device that transmits or receives
NMEA 0183 data, however, a communications cable is not available for
the unit at this time. If you need to create a NMEA 0183 connection,
consult customer service. Service contact information is located in the
back of this manual.
NMEA Wiring
To exchange NMEA data, the unit has one NMEA 0183 version 2.0
communication port. Com port one (Com-1) can be used to receive
32
NMEA format GPS data. The com port can also transmit NMEA format
GPS data to another device. A data cable should contain three wires.
Com-1 uses the yellow wire to transmit, the orange wire to receive and
the shield wire for signal ground.

Mounting the Unit: Bracket or Portable
You can install the sonar unit on the top of a dash with the supplied
gimbal bracket. It can also be mounted on a portable power supply.
If you use the supplied bracket, you may be interested in the optional
R-A-M bracket mounting system. This converts the unit's gimbal
bracket to a swivel mount.
Optional R-A-M mounting system.
33
Bracket Installation
Mount the unit in any convenient location, provided there is clearance
behind the unit when it's tilted for the best viewing angle. This must
be a location with a clear view of the sky, so the internal GPS
antenna can lock-on to the satellite signals. You should also make
sure there is enough room behind the unit to attach the power and
transducer cables.
Holes in the bracket's base allow wood screw or through-bolt mounting.
You may need to place a piece of plywood on the back side of thin fiberglass panels to reinforce the panel and secure the mounting hardware.
Front
Install the gimbal bracket. Position the bracket so the arms slope toward the front of your unit.
Drill a 1-inch (25.4 mm) hole in the dash for the power and transducer
cables. The best location for this hole is immediately under the gimbal
bracket location. This way, the bracket can be installed so that it covers
the hole, holds the cables in position and results in a neat installation.
Some customers prefer to mount the bracket to the side of the cable
hole. It's a matter of personal preference.

Pass the power cable's bare-wire end down though the hole from the
top. If you want, you can fill in the hole around the cables with a good
marine sealant. (Some marine dealers stock cable hole covers to conceal
the opening.) No matter what type of installation you prefer, be sure to
leave enough slack in the cables to allow tilting or swiveling the unit. If
you choose to fill in the hole, be sure to position the cables against the
rear edge of the hole as you apply the fill material.
Before positioning the bracket, be sure to hold the cables against the
rear edge of the hole. Then, slide the bracket over the hole and butt the
rear of the bracket base firmly against the cables, pinning them in
place against the side of the hole. Finally, fasten the bracket to the
dash. Attach the unit to the gimbal bracket using the supplied gimbal
knobs and washers.
Portable Installation
Like many Eagle products, this unit is capable of portable operation by
using an optional portable power pack (PPP). The power pack and an
optional portable transducer expand the uses for your sonar unit. The
PPP makes it easy to use the unit on your boat or take it to the dock, on
a float tube, on an ice fishing trip or use it as a second sonar in a
friend's boat.
35
Most LEI portable power packs can be used with eight "D" cell alkaline
batteries. Some use an optional sealed, rechargeable battery. For information on the PPP for your unit, see the accessory ordering information inside the back cover of this manual.
"D" cell battery
Install batteries in typical portable power pack.
MMC or SD Card Memory Card Installation
Your unit uses a MultiMedia Card to store information, such as sonar
logs, custom maps, waypoints, trails and other GPS data. The unit can
also use Secure Digital Cards (SD card) to store data.
NOTE:
Throughout this manual, we will use the term MMC, but just remember your unit can use an MMC or SD card to store data.
Both of these solid-state flash memory devices are about the size of a
postage stamp. An SD card is slightly thicker than an MMC. As this
manual went to press, MMCs were available in storage capacities of 8
MB, 16 MB, 32 MB, 64 MB and 128 MB. SD cards were available in
capacities of 8 MB, 16 MB, 32 MB, 64 MB, 128 MB, 256 MB and 1 GB.
Additional MMC cards are available from LEI Extras. See ordering information inside the back cover of this manual. MMCs and SD cards
are also available at many camera and consumer electronics stores.
The MMC slot is located in a compartment on the front of the case. The
compartment door is located at the lower right corner. The following
figure shows a close-up with the door opened.

You can customize how the Sonar Page displays its pictures and other
data in many ways. Your unit also includes several special sonar features
and options that can help you better interpret the underwater scene.
We'll discuss all of those features and options in Sec. 4, but to show you
how easy this unit is to operate, the following page contains a simplified, 10-step quick reference that will cover most fish finding situations.
The quick reference describes how your unit will operate with all the
sonar features in their automatic modes, which are set at the factory.
46
Basic Sonar Quick Reference
1. Mount the transducer, antenna and unit. Connect the unit to electric
power and the transducer. (If GPS operation is desired, connect GPS
antenna, too.) Make sure the MMC is in. (See complete installation details beginning on page 13.)
2. Launch your boat.
3. To turn on the unit, press and release PWR key.
4. Opening screen displays Map Page. Rotate through the four main
Page screens (Map Page, Satellite Status Page, Navigation Page and
Sonar Page) by pressing PAGES|← → to select Page Name|EXIT.
Switch Pages to display Sonar Page.
5. If GPS data is desired, wait while unit locates satellites and calculates
current position. When the unit acquires position, a tone sounds and a position acquired message appears.
6. With position acquired (if desired), head for your fishing grounds.
Your unit will automatically display digital depth and surface water
temperature in the top left corner of the screen.
The auto settings will track the bottom, displaying it in the lower portion of the screen. The full sonar chart will scroll from right to left,
showing you what's under the boat as you cruise across the water. You
can change the display by:
Zoom in to enlarge the chart for more detail: press ZIN.
Zoom out to return to full chart mode: press ZOUT.
7. Watch the display for the appearance of fish symbols (or arches, if
Fish I.D. is turned off). When you see fish symbols or arches, you've
found fish! Stop the boat and get your lure or bait into the water at the
depth indicated on the sonar chart.
8. Gauge the fish depth by visually comparing the fish symbols or
arches with the depth scale on the right side of the screen, or get a
more accurate measure with the Depth Cursor. Press MENU|↓ to DEPTH
CURSOR|ENT. Press ↓ ↑ to align the cursor line with the fish arch. The
exact depth appears in a box at the right end of the cursor line. To clear
the cursor, press EXIT.
9. If you are drifting at a very low speed or anchored, you are not moving fast enough for a fish to return the tell-tale fish arch signal. As you
drift over a fish or as a fish swims through the transducer's signal cone,
the fish echo will appear as a straight line suspended between the surface and the bottom when Fish I.D. is turned off.
10. To turn off the unit, press and hold PWR key for three seconds.
47
Sonar Operations
As you can see from the quick reference on the previous page, basic operation
is pretty easy, right out of the box. If you are a sonar novice, try operating the
unit with the factory defaults until you get a feel for how it's working.
As you're learning the basics, there is one setting you might want to tinker
with from time to time — Sensitivity.
Sensitivity controls the unit's ability to pick up echoes. If you want to see
more detail, try increasing the sensitivity, a little at a time. There are situations when too much clutter appears on the screen. Decreasing the sensitivity
can reduce the clutter and show the strongest fish echoes, if fish are present.
As you change the sensitivity setting, you can see the difference on the chart
as it scrolls.
Fig. 1
Fig. 2
Fig. 3
Fig. 4
These figures show results of different sensitivity levels on the same location. Fig. 1: Sensitivity at 88 percent, determined by Auto Sensitivity.
Typical of full auto mode. Fig. 2: Sensitivity set at 75 percent. Fig. 3: Sensitivity set at 50 percent. Fig. 4: Sensitivity set at 100 percent.
48
You can change the sensitivity level whether you are in Auto Sensitivity
mode or Manual Sensitivity mode. The adjustment method works the
same in both modes, but gives you slightly different results.
Adjusting sensitivity in Auto Sensitivity Mode is similar to manually adjusting a car's speed with the accelerator pedal while cruise control is on.
You can tell the car to run faster, but when you let off the gas the cruise
control automatically keeps you from running slower than the minimum
speed setting. In the unit, auto mode will let you increase sensitivity to 100
percent, but the unit will limit your minimum setting. This prevents you
from turning sensitivity down too low to allow automatic bottom tracking.
When you change the setting with auto turned on, the unit will continue to
track the bottom and make minor adjustments to the sensitivity level, with
a bias toward the setting you selected.
Adjusting sensitivity in Manual Sensitivity Mode is similar to driving a
car without cruise control — you have complete manual control of the
car's speed. In the unit, manual mode allows you to set sensitivity at
100 percent (maximum) or zero percent (minimum.) Depending on water conditions, the bottom signal may completely disappear from the
screen when you reduce sensitivity to about 50 percent or less.
Try adjusting sensitivity in both auto and manual modes to see how
they work.
To adjust sensitivity:
1. Press MENU|ENT.
2. The Sensitivity Control Bar appears. Use ↑ ↓ to adjust the sensitivity. When it is set at the desired level, press EXIT.

49
NOTE:
If you want to change sensitivity in Manual Mode, turn off Auto
Sensitivity. From the Sonar Page, press MENU|↓ to AUTO SENSITIVITY|ENT|↑ to SENSITIVITY|ENT. Press ↓ ↑ to pick a different sensitivity setting. When it is set at the desired level, press EXIT.
Tip:
While you are experimenting and learning, it is possible to scramble
the settings so the sonar picture disappears from your screen. If that
happens, remember, it is easy to switch back to full automatic operation. Just restore the factory auto settings.
To Restore Factory Settings
1. Press MENU|MENU|↓ to SYSTEM SETUP|ENT|↓ to RESET OPTIONS|ENT.
2. A confirmation message appears. Press ← to YES|ENT. All options
are reset and the unit reverts back to the Map Page at a 4000-mile
zoom range. Any recorded sonar logs or GPS data will be unchanged.
Fish Symbols vs. Full Sonar Chart
You may have noticed in the quick reference that we used fish arches in
full sonar chart mode for our example, and not the popular Fish I.D.
fish symbol feature. Here's why.
Fish I.D. is an easier way for a sonar novice to recognize a fishy signal
return when he sees it. However, locating fish by symbol only has some
limitations.
Your sonar unit's microprocessor is remarkably powerful, but it can be
fooled. Some of the echoes calculated to be fish could be tree limbs or turtles! To see what's under your boat in maximum detail, we recommend
you turn off Fish I.D. and begin learning to interpret fish arches.
Fish I.D. is most handy when you're in another part of the boat or performing some task that prevents you from watching the sonar screen.
Then, you can turn on Fish I.D. and the audible fish alarm. When that
lunker swims under your boat, you'll hear it!
Fish I.D. can also be useful when you want to screen out some of the
sonar detail gathered by your unit. For example, in one case fisherman
in San Francisco Bay saw clouds of clutter in the water but no fish
arches. When a down rigger was pulled up, it brought up several small
jellyfish. The fisherman switched their sonar to Fish I.D., which
screened out the schools of jellyfish and clearly showed the game fish
there as fish symbols.
The sonar options section discusses Fish I.D., fish alarms and other
features in greater detail.
50
Section 4: Sonar Options & Features
ASP (Advanced Signal Processing)
The ASP feature is a noise rejection system built into the sonar unit
that constantly evaluates the effects of boat speed, water conditions
and interference. This automatic feature gives you the best display possible under most conditions.
The ASP feature is an effective tool in combating noise. In sonar terms,
noise is any undesired signal. It is caused by electrical and mechanical
sources such as bilge pumps, engine ignition systems and wiring, air
bubbles passing over the face of the transducer, even vibration from the
engine. In all cases, noise can produce unwanted marks on the display.
The ASP feature has four settings — Off, Low, Medium and High. If
you have high noise levels, try using the "High" ASP setting. However,
if you are having trouble with noise, we suggest that you take steps to
find the interference source and fix it, rather than continually using the
unit with the high ASP setting.
There are times when you may want to turn the ASP feature off. This
allows you to view all incoming echoes before they are processed by the
ASP feature.

2. Press ↓ to NOISE REJECTION|ENT.
3. Press ↓ ↑ to select a setting, then press ENT.
4. To return to the main page display, press EXIT|EXIT.
51
Alarms
This unit has three different types of sonar alarms. The first is the Fish
Alarm. It sounds when the Fish I.D. feature determines that an echo
is a fish.
Another alarm is the Zone Alarm, which consists of a bar on the side of
the screen. Any echo on the chart that appears inside this bar triggers
this alarm.
The last alarm is the Depth Alarm, which has both a Shallow and a
Deep setting. Only the bottom signal will trigger this alarm. This is
useful as an anchor watch, a shallow water alert or for navigation.
Depth Alarms
The depth alarms sound a tone when the bottom signal goes shallower
than the shallow alarm's setting or deeper than the deep alarm's setting. For example, if you set the shallow alarm to 10 feet, the alarm will
sound a tone if the bottom signal is less than 10 feet. It will continue to
sound until the bottom goes deeper than 10 feet.
The deep alarm works just the opposite. It sounds a warning tone if the
bottom depth goes deeper than the alarm's setting. Both depth alarms
work only off the digital bottom depth signals. No other targets will trip
these alarms. These alarms can be used at the same time or individually.

Calibrate Speed
The speed sensor can be calibrated to compensate for inaccuracies. Before you change the setting, first calculate the percentage that the
speed is off. You will enter this percentage in a moment.
For example, if you figure the sensor is reading 10 percent faster than
actual speed, you will enter – 10 in the calibration window. If the sensor is reading 5 percent slower than true speed, you will enter + 5 in
the window.
A good way to gauge your speed sensor's performance is to compare its
reading with the ground speed measured by your unit's GPS functions.
When you make a run to compare GPS ground speed to speed sensor
speed, perform your test in relatively calm water free of current, if possible. Unless, you are taking the current speed into consideration when
making your calculation. After you have a correction figure, you are
ready to calibrate the speed sensor.
54
1. Press MENU|MENU|↓ to SONAR SETUP|ENT|↓ to CALIBRATE WATER
SPEED|ENT.
2. Enter the number you calculated earlier. Press ↑ ↓ to change the
first character (+ or –), then press → to move the cursor to the first
number and repeat until the percentage is correct, then press EXIT.
Chart Speed
The rate that echoes scroll across the screen is called the chart speed.
The default is maximum .We recommend you leave the speed set there
for most all fishing conditions. You, however, might consider experimenting with chart speed when you are stationary or drifting very
slowly. You may sometimes achieve better images as you slow down the
chart speed to match how fast you are moving across the bottom.
If you are at anchor, ice fishing or fishing from a dock, experiment with
a chart speed around 50 percent. If you are drifting slowly, try a chart
speed around 75 percent. When you are stationary and a fish swims
through the sonar signal cone, the image appears on the screen as a
long line instead of a fish arch. Reducing the chart speed may result in
a shorter line that more closely resembles a regular fish return.
Sonar Page menu with Chart Speed selected (left).

2. The Chart Speed Control Bar appears. Press ↓ ↑ to adjust chart
speed.
3. When it is set at a desired level, press EXIT.
55
ColorLine
ColorLine lets you distinguish between strong and weak echoes. It
paints a brighter color on targets that are stronger than a preset value.
This allows you to tell the difference between a hard and soft bottom.
For example, a soft, muddy or weedy bottom returns a weaker signal
which is shown with a narrow, colored line (dark blue tinged with red
or a little yellow.) Since fish are among the weakest echoes, they show
up mostly as blue arches. A hard bottom or other relatively hard target
returns a strong signal which causes a wider brightly colored line (reddish yellow to bright yellow.)
If you have two signals of equal size, one with red to yellow color and
the other without, then the target with brighter color (yellow) is the
stronger signal. This helps distinguish weeds from trees on the bottom,
or fish from structure.
ColorLine is adjustable. Experiment with your unit to find the ColorLine setting that's best for you.

FasTrack
This feature automatically converts all echoes to short horizontal lines
on the display's far right side. The graph on the rest of the screen continues to operate normally. FasTrack gives you a rapid update of conditions directly under the boat. This makes it useful for ice fishing, or
when you're fishing at anchor. When the boat is not moving, fish signals are long, drawn out lines on a normal chart display. FasTrack converts the graph to a vertical bar graph that, with practice, makes a useful addition to fishing at a stationary location.

Fish I.D.
The Fish I.D. feature identifies targets that meet certain conditions as
fish. The microcomputer analyzes all echoes and eliminates surface
clutter, thermoclines, and other signals that are undesirable. In most
instances, remaining targets are fish.
60
The Fish I.D. feature displays fish symbols on the screen in place of the
actual fish echoes.
There are several fish symbol sizes. These are used to designate the
relative size between targets. In other words, Fish I.D. displays a small
fish symbol when it thinks a target is a small fish, a medium fish symbol on a larger target and so on.
The sonar's microcomputer is sophisticated, but it can be fooled. It can't
distinguish between fish and other suspended objects such as trotlines,
turtles, submerged floats, air bubbles, etc. Individual tree limbs extending outwards from a group of limbs is the hardest object for the
Fish I.D. feature to distinguish from fish.
You may see fish symbols on the screen when actually, there are no
fish. The reverse is also true. The illustrations on the next page show
how Fish I.D. can actually miss fish that are present.
Does that mean Fish I.D. is broken? No — the feature is interpreting
sonar returns in a specific way to help take some of the work out of
reading the screen. Remember: Fish I.D. is one of the many tools we
provide so you can analyze your sonar returns for maximum fish finding information. This and other features can help you successfully "see"
beneath the boat under varied water and fishing conditions. So, practice with the unit in both the Fish I.D. mode and without to become
more familiar with the feature. The default for Fish I.D. is off.

Frequency (Change Transducer Frequency)
The SeaCharter 502cDF transducer operates with both 200 kHz and 50
kHz. The 200 kHz frequency has a 12° cone angle and the 50 kHz frequency has a 35° cone angle.
The default frequency is 200 kHz, which is best for use in shallow water
(about 300 feet or less). This frequency is the best choice for about 80
percent of the fresh and salt water sport fishing applications. When you
get into very deep salt water, 300 to 500 feet or deeper, the 50 kHz frequency is the best choice.
The 200 kHz transducer will give you better detail and definition, but
less depth penetration. The 50 kHz transducer will give you greater
depth penetration, but a little less detail and less definition. (Remember,
all sonar units typically read deeper in fresh water than in salt water.)
62
There is a common exception to these rules. Some fishermen on freshwater lakes (or the ocean) using downriggers like to see them on the
sonar. In many of those cases, you'll see a 50 kHz transducer frequency
in use because the wider cone angle lets them watch the bait.

Ping Speed & HyperScroll
Ping Speed controls the rate at which the unit broadcast sonar sound
waves — pings — into the water. The unit has a default ping speed of
67
50 percent. At normal boating speeds, this automatically provides
enough return echoes to refresh the screen and scroll the chart at
maximum chart speed.
However, when you are running at high speeds, or just want the fastest
possible screen update, you may want to use the HyperScroll feature.
When you change the Ping Speed to any setting greater than 50 percent, the unit automatically enters HyperScroll mode.
These faster ping rates allow you to maintain a high-detail picture on
the screen, and the screen refresh rate and chart scroll speed can keep
pace with the boat as it moves quickly over the bottom terrain.
When using HyperScroll, you may also need to manually decrease the
sensitivity for optimum performance. Depending on water depth and
other conditions, HyperScroll may cause a second bottom echo to return
to the transducer during the next ping cycle, or sounding. This can result
in a large amount of clutter appearing on the screen. If this occurs, just
decrease the sensitivity to a level that eliminates the clutter. When you
turn HyperScroll off, you can return to your original sensitivity level.
Sonar Menu with Ping Speed selected (left).

When you boost ping speed and switch into HyperScroll, the width of
the FasTrack bar graph display doubles in width at the right side of the
screen. This allows you to better see the virtually instantaneous sonar
returns, just as you would on a flasher sonar unit. For more information on FasTrack, see its entry in this section.

Set Keel Offset
This unit measures water depth from the face of the transducer. Since
the transducer is installed below the water surface, the distance displayed by the digital depth, chart depth scale, chart cursor or fish symbols is not the exact water depth. If the transducer is 1 foot below the
surface, and the screen shows the water depth as 30 feet, then the actual depth is 31 feet.
On sailboats or other large vessels with deep drafts, the distance between the transducer installation and the keel or lower engine unit can
be several feet. In those cases, an inexact depth reading could result in
grounding or striking underwater structure. The Keel Offset feature
eliminates the need for the navigator to mentally calculate how much
water is under his keel.
Keel Offset lets you calibrate the digital depth, chart depth scale, chart
cursor depth and fish symbol depth displayed on the screen. To calibrate
the depth indicators, first measure the distance from the face of the
transducer to the lowest part of the boat. In this example, we will use 3.5
feet. This will entered as a negative 3.5 feet, which makes the depth indicators perform as if the transducer's lower in the water than it really is.
1. Press MENU|MENU|↓ to SONAR SETUP|ENT|↓ to SET KEEL OFFSET|ENT.
2. The Keel Offset dialog box appears. Press ↓ to change the plus (+)
sign to a minus (–) sign.
3. Press → to the first number, then press ↑ to change the number to 3
4. Press → to the second number, then press ↑ to change the number to
5 and press EXIT. The depth indicators now accurately show the depth
of water beneath the keel.
NOTE:
If knowing the exact depth of water beneath the keel is less important,
calibrate the depth indicators so they show actual water depth from
surface to bottom. To do this, measure the distance from the face of the
transducer up to the surface — the water line on the boat. In this example, we will use 1.5 feet. This will be entered as a positive 1.5 feet,
which makes the depth indicators perform as if the transducer is
higher in the water than it really is.
1. Press MENU|MENU|↓ to SONAR SETUP|ENT|↓ to SET KEEL OFFSET|ENT.
2. The Keel Offset dialog box appears with a plus (+) sign at the
front of the box.
70
3. Press → to the first number, then press ↑ to change the number to 1.
4. Press → to the second number, then press ↑ to change the number to 5 and press EXIT. The depth indicators now accurately show
the water depth from surface to bottom.
Sensitivity & Auto Sensitivity
The sensitivity controls the ability of the unit to pick up echoes. Sensitivity can be adjusted, because water conditions vary greatly. A low
sensitivity level (from zero to 50 percent) excludes much of the bottom
information, fish signals, and other target information.
High sensitivity levels let you see this detail, but it can also clutter the
screen with many undesired signals. Typically, the best sensitivity level
shows a good solid bottom signal with Colorline and some surface clutter.
Automatic Sensitivity
The default sensitivity mode is automatic. The unit bases the sensitivity level on water depth and conditions. When the unit is in the automatic mode, sensitivity is automatically adjusted to keep a solid bottom
signal displayed, plus a little more power. This gives it the capability to
show fish and other detail.
However, situations occur when it becomes necessary to increase or decrease the sensitivity. This typically happens when you wish to see
more detail, so an increase in sensitivity is indicated. Or, wave action
and boat wakes can create enough tiny air bubbles to clutter much of
the water column. In that case, a decrease in sensitivity is indicated to
reduce some of the clutter.
The control bar used to adjust sensitivity up or down is the same
whether the unit is in the automatic or manual mode. In automatic you
can adjust sensitivity up to 100 percent but the unit will limit your
minimum setting. In auto, the unit will continue to make small adjustments, allowing for the setting you selected.
In manual mode, you have complete control over sensitivity, with the
ability to set it anywhere from zero to 100 percent. Once you select a
level in manual, the unit will continue to use that exact sensitivity setting until you change it or revert to auto mode.
To adjust sensitivity in auto mode:
1. Press MENU|ENT.
2. The Sensitivity Control Bar appears. Press ↓ ↑ to adjust sensitivity.
When it is set at the desired level, press EXIT.

desired level, press EXIT.
NOTE:
To return to the original factory setting for Auto Sensitivity, see the
entry in this section on Reset Options. If sensitivity is in manual
mode, the Reset Options command will switch it back to Auto.
Tip:
For quicker sensitivity adjustments, try leaving the Sensitivity
Control Bar on the screen as the chart scrolls. You can see the
changes on the screen as you press the up or down arrows. This is
handy when there's a lot of clutter in the water and you are
matching the sensitivity to rapidly changing water conditions.

The Pages Menu with the Map option list (left). Active Map is listed at
the top of the map page. Map with Sonar split screen (right). Sonar is
the active page, denoted by the blue bar at the top of the page.
When this screen is displayed, you can switch back and forth between the
two windows by activating the sonar or map window. To do this, press
PAGES|PAGES. "Active Map" will appear at the top of the map page when
it is activated. Press PAGES|PAGES again and the bar at the top of the
sonar page turns blue.
Sonar Simulator
This unit has a built-in simulator that lets you run it as if you were on
the water. All sonar features and functions are useable. To use the
simulator:
1. From the Sonar Page, press MENU|MENU|↓ to SONAR SETUP|ENT|↓ to
SONAR SIMULATOR|ENT|ENT|EXIT. Repeat these steps to turn it off.
NOTE:
If you turn on your unit before attaching a transducer, it may enter
a demo mode. The words demo mode flash on the bottom of the
screen and a sonar chart plays much like the simulator. Unlike the
simulator, the demo mode is for demonstration only and will automatically stop as soon as you turn on the unit with a transducer attached.

While you are in the Sonar Simulator menu, don't forget to check
Simulate Position if you want to run the sonar and GPS simulators
simultaneously. As you review sonar logs, you can create waypoints
to mark sites you want to revisit.
While the simulator is running, you can switch from one chart log
to another by opening the Sonar Simulator menu and using the instructions in step 2 to select a different chart.
Tip:
There's more than one way to play a recorded sonar chart. You can
also turn on the simulator from the MMC files list.
1. Press MENU|MENU|↓ to BROWSE MMC FILES|ENT|ENT.
2. Press ↓ ↑ to chart name|ENT|↓ to PLAY|ENT|EXIT.
NOTE:
For some great practice, try running the Sonar Simulator and the
GPS Simulator at the same time. This will give you a feel for how
the unit will work in the field.
Stop Chart
If you are running multiple units on a boat or using this unit in a car,
there are times when you may want to turn off the sonar. This command turns off the sonar. Sonar restarts automatically each time you
turn on your unit.
From the Sonar Page press MENU|↓ to STOP CHART|ENT|EXIT.

Surface Clarity
The markings extending downward from the zero line on the chart are
called surface clutter. These markings are caused by wave action, boat
78
wakes, temperature inversion and more. The surface clarity control
reduces or eliminates surface clutter signals from the display. It does
this by changing the sensitivity of the receiver, decreasing it near the
surface and gradually increasing it as the depth increases. There are
three levels of surface clarity available: low, medium, or high. It can
also be turned off. The default level is off.
Surface clutter

Clarity is turned off (center) and set to high (right).
To adjust the Surface Clarity level:
1. From the Sonar Page, press MENU|↓ to SONAR FEATURES|ENT|ENT.
2. Press ↓ ↑ to select clarity level|EXIT repeatedly to get back to the
main page display.
Zoom & Zoom Bar
Zooming the display is a common, fast and easy method used to enlarge
small detail, fish signals and the bottom. This unit lets you zoom the
display quickly and easily by pressing the Zoom In key, ZIN. Pressing
ZIN once doubles the size (2X) of all echoes on the screen. Pressing it
again quadruples the size of the echoes (4X). When turned on, the zoom
bar on the far right side of the screen shows which echoes will be displayed on the screen when the ZIN key is pressed.
To turn on the zoom bar, press MENU|↓ to SONAR FEATURES|ENT. Press ↓
to ZOOM BAR|ENT|EXIT|EXIT. Repeat these steps to turn it off.
For example, pressing the ZIN key once will enable a 2X zoom which
will show all echoes that are between the top and bottom of the 2X
zoom bar. Pressing the key again will give a 4X zoom and only the echoes between the top and bottom of the 4X bar will show on the screen.
Press the Zoom Out key, ZOUT, to return to the normal display mode.

Zoom Pan
Your unit has the handy ability to zoom in on any portion of the water
column with just the touch of an arrow key. The Zoom Pan feature lets
you rapidly move the zoomed area up and down to different depths. By
pointing your zoom at different portions of the chart as it scrolls, you can
get a close-up look at structure or cover below you.
To use Zoom Pan, switch to a manual Depth Range setting and turn on
2X or 4X Zoom. Then press ↑ ↓ to pan up and down the water column.

Section 5: Sonar Troubleshooting
If your unit is not working, or if you need technical help, please use the
following troubleshooting section before contacting the factory customer
service department. It may save you the trouble of returning your unit
for repair. For contact information, refer to the last page, just inside the
back cover of this manual.
Unit won't turn on:
1. Check the power cable's connection at the unit. Also check the wiring.
2. Make sure the power cable is wired properly. The red wire connects
to the positive battery terminal, black to negative or ground.
3. Check the fuse.
4. Measure the battery voltage at the unit's power connector. It should
be at least 10 volts. If it isn't, the wiring to the unit is defective, the
battery terminals or wiring on the terminals are corroded, or the battery needs charging.
Unit freezes, locks up or operates erratically:
1. Electrical noise from the boat's motor, trolling motor, or an accessory
may be interfering with the sonar unit. Rerouting the power and transducer cables away from other electrical wiring on the boat may help.
Route the sonar unit's power cable directly to the battery instead of
through a fuse block or ignition switch
2. Inspect the transducer cable for breaks, cuts, or pinched wires.
3. Check the transducer and power connector. Make sure it's securely
plugged in to the unit.
Weak bottom echo, digital readings erratic or no fish signals:
1. Make sure the transducer is pointing straight down. Clean the face of
the transducer. Oil, dirt and fuel can cause a film to form on the transducer, reducing its effectiveness. If the transducer is mounted inside the
hull, be sure it is shooting through only one layer of fiberglass and that it
is securely bonded to the hull. When attaching a transducer to the inside
of a hull, ONLY use the epoxy available from LEI (order information is
inside the back cover). Do NOT use RTV silicone rubber adhesive or any
other type of epoxy. The LEI epoxy is specially formulated so that it will
cure properly for shoot-through applications.
2. Electrical noise from the boat's motor can interfere with the sonar.
This causes the sonar to automatically increase its discrimination or
noise rejection feature. This can cause the unit to eliminate weaker
signals such as fish or even structure from the display.
81
3. The water may be deeper than the sonar's ability to find the bottom.
If the sonar can't find the bottom signal while it's in the automatic
mode, the digital sonar display will flash continuously. It may change
the range to limits far greater than the water you are in. If this happens, place the unit in the manual mode, then change the range to a
realistic one, (for example, 0-100 feet) and increase the sensitivity. As
you move into shallower water, a bottom signal should appear.
4. Check the battery voltage. If the voltage drops, the unit's transmitter
power also drops, reducing its ability to find the bottom or targets.
Bottom echo disappears at high speeds or erratic digital reading or weak bottom echo while boat is moving:
1. The transducer may be in turbulent water. It must be mounted in a
smooth flow of water in order for the sonar to work at all boat speeds. Air
bubbles in the water disrupt the sonar signals, interfering with its ability
to find the bottom or other targets. The technical term for this is cavitation.
2. Electrical noise from the boat's motor can interfere with the sonar.
This causes the sonar to automatically increase its discrimination or
noise rejection feature. This can cause the unit to eliminate weaker
signals such as fish or even structure from the display. Try using resistor spark plugs or routing the sonar unit's power and transducer cables
away from other electrical wiring on the boat.
No fish arches when the Fish I.D. feature is off:
1. Make sure the transducer is pointing straight down. This is the most
common problem if a partial arch is displayed.
2. The sensitivity may not be high enough. In order for the unit to display a fish arch, it has to be able to receive the fish's echo from the time
it enters the cone until it leaves. If the sensitivity is not high enough,
the unit shows the fish only when it is in the center of the cone.
3. Use the Zoom feature. It is much easier to display fish arches when
zoomed in on a small range of water than a large one. For example, you
will have much better luck seeing fish arches with a 30 to 60 foot range
than a 0 to 60 foot range. This enlarges the targets, allowing the display to show much more detail.
4. The boat must be moving at a slow trolling speed to see fish arches.
If the boat is motionless, fish stay in the cone, showing on the screen as
straight horizontal lines.
NOISE
A major cause of sonar problems is electrical noise. This usually appears on the sonar's display as random patterns of dots or lines. In severe cases, it can completely cover the screen with black dots, or cause
the unit to operate erratically, or not at all.
82
To eliminate or minimize the effects of electrical noise, first try to determine the cause. With the boat at rest in the water, the first thing
you should do is turn all electrical equipment on the boat off. Make sure
the engine is also off. Turn your sonar on, then turn off Noise Reject
[also known as the ASP feature (Advanced Signal Processing)]. Sensitivity should be set at 90-95 percent. There should be a steady bottom
signal on the display. Now turn on each piece of electrical equipment on
the boat and view the effect on the sonar's display. For example, turn
on the bilge pump and view the sonar display for noise. If no noise is
present, turn the pump off, then turn on the VHF radio and transmit.
Keep doing this until all electrical equipment has been turned on, their
effect on the sonar display noted, then turned off.
If you find noise interference from an electrical instrument, trolling motor, pump, or radio, try to isolate the problem. You can usually reroute
the sonar unit's power cable and transducer cable away from the wiring
that is causing the interference. VHF radio antenna cables radiate
noise when transmitting, so be sure to keep the sonar's wires away
from it. You may need to route the sonar unit's power cable directly to
the battery to isolate it from other wiring on the boat.
If no noise displays on the sonar unit from electrical equipment, then
make sure everything except the sonar unit is turned off, then start the
engine. Increase the RPM with the gearshift in neutral. If noise appears on the display, the problem could be one of three things; spark
plugs, alternator, or tachometer wiring. Try using resistor spark plugs,
alternator filters, or routing the sonar unit's power cable away from
engine wiring. Again, routing the power cable directly to the battery
helps eliminate noise problems. Make sure to use the in-line fuse supplied with the unit when wiring the power cable to the battery.
When no noise appears on the sonar unit after all of the above tests,
then the noise source is probably cavitation. Many novices or persons
with limited experience make hasty sonar installations which function
perfectly in shallow water, or when the boat is at rest. In nearly all
cases, the cause of the malfunction will be the location and/or angle of
the transducer. The face of the transducer must be placed in a location
that has a smooth flow of water at all boat speeds. Read your transducer owner's manual or the Installation instructions (Sec. 2) in this
manual for the best mounting position.

Pages
The unit has four Page displays: Satellite Status Page, Navigation Page,
Map Page and Sonar Page. They are accessed by pressing the PAGES key,
then using ← → to select a Page.
87
Pages Menu showing some Map display options.
Sonar Page
The Sonar Page displays the sonar chart, a view of the water column
from the surface to the bottom. The chart scrolls across the screen from
right to left, displaying signal echoes of fish, structure and the bottom.
The Sonar Page is discussed in detail in Sec. 3. To get to the Sonar
Page, press the PAGES key, then use ← → to select SONAR. Clear the
Pages Menu by pressing EXIT.
Satellite Status Page
The Satellite Status Page, shown in the following images, provides detailed information on the status of the unit's satellite lock-on and position acquisition. To get to the Satellite Status Page, press the PAGES
key, then use ← → to select STAT.
No matter what Page you are on, a flashing current position indicator/question mark symbol and flashing GPS data displays indicate that
satellite lock has been lost and there is no position confirmed. The Satellite Status Page shows you the quality and accuracy of the current
satellite lock-on and position calculation.
WARNING:
Do not begin navigating with this unit until the numbers
have stopped flashing!
88
Satellite Status Page. The first figure (left) shows the unit has not
locked on to any satellites and does not have a fix on its position. In the
second figure, the unit has a satellite lock-on with a 3D position acquired (latitude, longitude and altitude) and WAAS reception.
This screen shows a graphical view of satellites that are in view. Each satellite is shown on the circular chart relative to your position. The point in the
center of the chart is directly overhead. The small inner ring represents 45°
above the horizon and the large ring represents the horizon. North is at the
top of the screen. You can use this to see which satellites are obstructed by
obstacles in your immediate area if the unit is facing north.
The GPS receiver is tracking satellites that are in bold type. The receiver hasn't locked onto a satellite if the number is grayed out, therefore it isn't being used to solve the position.
Beneath the circular graph are the bar graphs, one for each satellite in
view. Since the unit has twelve channels, it can dedicate one channel
per visible satellite. The taller the bar on the graph, the better the unit
is receiving the signals from the satellite.
NOTE:
One of the data display options for the Satellite Status page is Position Error (horizontal position error), which can appear in one of
the page's data boxes. Position Error will show you the expected error from a benchmark location. In other words, if the Position Error
box shows 50 feet, then the position shown by the unit is estimated
to be within 50 feet of the actual location.
This also gives you an indicator of the fix quality the unit currently
has. The smaller the position error number, the better (and more accurate) the fix is. If the position error flashes dashes, then the unit
hasn't locked onto the satellites, and the number shown isn't valid.
(For details, see the Customize Page Displays entry in Sec. 8.)
89
The Satellite Status Page has its own menu, which is used for setting
various options. To access the Satellite Status Page Menu, from the
Status Page, press MENU.
Navigation Page
This screen has a compass rose that not only shows your direction of
travel, but also the direction to a recalled waypoint. To get to the Navigation Page, press PAGES|← → to NAVIGATION|EXIT.
The navigation screen looks like the one below when you're not navigating to a waypoint or following a route or trail. Your position is
shown by an arrow in the center of the screen. Your trail history, or
path you've just taken, is depicted by the line extending from the arrow.
The arrow pointing down at the top of the compass rose indicates the current track (direction of travel) you are taking.

When navigating to a waypoint, the Navigation screen looks like the
following figure. Your ground speed, track, distance and bearing to
waypoint, and course are all shown digitally on this screen.
NOTE:
Remember, when the Speed, Track and Position information displays are flashing, satellite lock has not been achieved and no position fix has been determined. A question mark will flash on the
present position arrow in the center of the compass rose.
Speed is your velocity as you travel. You can customize the Speed data
box to display Closing Speed instead. Closing Speed, also known as ve90
locity made good, is your speed toward a waypoint. For instructions, see
the Customize Page Displays entry in Sec. 8.
Track is the heading, or the current direction you are actually traveling. Bearing is the direction of a line-of-sight from your present position
to the destination. No matter what direction you are steering, the
Bearing window shows the compass direction straight to the destination from your location at the moment. Distance shows how far it is to
the waypoint you're navigating toward.
The Off Course window shows the current cross track error. This shows
the distance you are off-course to the side of the desired course line. The
course line is an imaginary line drawn from your position when you
started navigating to the destination waypoint. The course line is shown on
the Navigation Page screen (and the Map Page screen) as a red line.

The cross track error range is shown on the compass rose as a wide,
white, corridor enclosing the course line. The outer edges of this white
corridor represent lines that show the current cross track error range.
The default for the cross track error range is 0.20 miles.
For example, if the present position symbol touches the right cross
track error line, then you are 0.20 miles to the right of the desired
course. You need to steer left to return to the desired course. You can
use the ZIN or ZOUT keys to change the cross track error range.
91
A circular symbol depicting your destination (waypoint) appears on the
screen as you approach the waypoint, as shown on the screen in the
preceding figure.
Travel Time is the time that it will take to reach your destination at
your present closing speed. (You can also customize the time data box
to show Arrival Time instead. Arrival Time is the local time it will be
when you arrive at the destination, based upon your present closing
speed and track.)
In the preceding example figure, the driver is headed northwest (a 345º
track) toward a waypoint 346º (bearing) away. The cross track error
range (white corridor) is 0.15 miles either side of the course. The driver
is headed toward trail waypoint 1, which is 0.3 miles away. The vehicle
is 234 feet right of the original course. Traveling at a speed of 17 mph,
the driver will arrive at the waypoint in 1 minute, 3 seconds.
The Navigation Page has its own menu, which is used for some advanced functions and for setting various options. (Options and setup
are discussed in Sec. 8). To access the Navigation Page Menu, from the
Navigation Page, press MENU.
Map Page
The Map Page screens show your course and track from a "bird's-eye"
view. By default, this unit shows the map with north always at the top
of the screen. (This can be changed. See the topic Map Orientation, in
Sec. 8.) If you're navigating to a waypoint, the map also shows your
starting location, present position, course line and destination. You
don't have to navigate to a waypoint, however, to use the map.
Map Page is the default screen that appears when you turn on the unit.
To get to the Map Page from another page, press PAGES|← → to
MAP|EXIT. When the Map Page is displayed, a screen similar to the following figures appears.
The arrow in the center of the screen is your present position. It points
in the direction you're traveling. The magenta line extending from the
back of the arrow is your plot trail, or path you've taken.
The map zoom range is the distance across the screen. This number
shows in the lower left corner of the screen. In the first of the following
example figures, the range is 4,000 miles from the left edge of the map
to the right edge of the map.
The Zoom In and Zoom Out keys zoom the map to enlarge or reduce its
coverage area and the amount of mapping detail shown. There are 40
available map zoom ranges, from 0.02 miles to 4,000 miles.
92
Map Page (left). Map page zoomed to 100 miles (center). Map page

If you are using only the factory-loaded background map, the maximum
zoom range for showing additional map detail is 15 miles. You can continue to zoom in closer, but the map will be enlarged without revealing
more map content (except for a few major city streets.) Load your own
high-detail custom map made with MapCreate (or a pre-made FreedomMap from LEI), and you can zoom in to 0.02 miles with massive
amounts of accurate map detail.

Arterial streets are visible at the 4-mile zoom range (left). Numerous
dots represent Points of Interest that are visible at the 2-mile range.
(center). At the 0.4-mile zoom (right), you can see an interstate highway
with an exit, major and minor streets as well as POI icons.
Background map vs. MapCreate map content
The background map includes: low-detail maps of the whole world (containing cities, major lakes, major rivers, political boundaries); and medium-detail maps of the United States.
93
The medium-detail U.S. maps contain: all incorporated cities; shaded
metropolitan areas; county boundaries; shaded public lands (such as
national forests and parks); some major city streets; Interstate, U.S.
and state highways; Interstate highway exits and exit services information; large- and medium-sized lakes and streams; and more than 60,000
navigation aids and 10,000 wrecks and obstructions in U.S. coastal and
Great Lakes waters
MapCreate custom maps include massive amounts of information not
found in the background map. MapCreate maps contain the searchable
Points of Interest database, all the minor roads and streets, all the
landmark features (summits, schools, radio towers, etc.) and smaller
lakes, rivers, streams, and ponds.
What's more important is the large scale map detail that allows your
GPS unit to show a higher level of position accuracy. For example, the
background map would show you the general outline and approximate
shape of a coastline or body of water, but the higher detail in MapCreate shows the shoreline completely and accurately. Many smaller islands would not be included in the background map, but are in MapCreate.
NOTE:
Available through LEI Extras (look inside back cover for accessory
ordering information), FreedomMaps are pre-made maps that contain all of the same information available in a custom MapCreate
map.
Tip:
In some urban areas, businesses are so close to one another that
their POI icons crowd each other on the screen. You can reduce
screen clutter and make streets and other map features easier to
see by turning off the display of POIs you're not watching for. (To
see how, check the text on Map Detail Category Selection, page 142.
It shows how to use the Map Categories Drawn menu to turn individual POI displays off and on.) Even though their display is turned
off, you can still search for POIs and their icons will pop-up when
your unit finds them for you.

Find Your Current Position
Finding your current position is as simple as turning the unit on. Under clear sky conditions, the unit automatically searches for satellites
and calculates its position in approximately one minute or less.
NOTE:
Clear sky means open sky, unobstructed by terrain, dense foliage or
structures. Clouds do not restrict GPS signal reception.
If for some reason satellite acquisition takes longer, you may be inside
a structure or vehicle or in terrain that is blocking signal reception. To
correct this, be sure you are positioned so that the unit's antenna module has as clear a view of the sky as possible, then turn the unit off and
back on again.
Moving Around the Map: Zoom & Cursor Arrow Keys
The map is presented from a bird's eye view perspective. The current
zoom range shows in the lower left corner of the screen.
1. Press the ZIN key (zoom in) to move in closer and see greater detail in
a smaller geographic area.
2. Press the ZOUT key (zoom out) to move farther away and see less map
detail, but a larger geographic area.
When you are traveling, the map will automatically move as you move.
This keeps your current location roughly centered on the screen.
You can manually pan or scroll the map northward, southward, eastward or westward by using the arrow keys, which launch the cross-hair
map cursor. This allows you to look at map places other than your current position. To clear the cursor, press EXIT, which jumps the map
back to the current position or the last known position.
Tip:
Use the cursor to determine the distance from your current position
(or last known position, when working indoors) to any map object or
location. Use the arrow keys to position the cursor over the object or
place. The distance, measured in a straight line, appears in the
popup data box. Press EXIT to clear the cursor.

Selecting Any Map Item With the Cursor
1. Use the zoom keys and the arrow keys to move around the map and
find the item you wish to select.
2. Use the arrow keys and center the cursor cross-hair on the desired object. On most items, a pop-up box will give the name of the selected item.
Tip:
This unit has an extremely handy Cursor Undo feature that lets
you instantly return to the previous location you were looking at
without scrolling. It works like this: Use the cursor (arrow keys) to
scroll the map to some far away location or waypoint. Press EXIT to
clear the cursor and jump back to your current position on the map.
When you want to take another peek at that distant place, just
press EXIT again. You can use this trick to toggle between your current position and your destination without a lot of scrolling.
Searching
Now that you've seen how the unit can find where you are, let's search
for something somewhere else. Searching is one of the most powerful
features in the Eagle GPS product line.
In this example, we'll look for the nearest fast-food restaurant. For more
information on different types of searches, refer to Sec. 9, Searching.
100
NOTE:
This example requires the Point of Interest (POI) database included
with a high detail MapCreate 6 custom map.
After the unit has acquired a position:
1. Press WPT|↓ to POI-RESTAURANTS.
2. You could search the entire restaurant category, but in this example
we will narrow our search. Press → to FAST FOOD CHAINS|ENT|↓ to
NEAREST|ENT.
3. The unit says it is calculating, then a list of restaurants appears,
with the closest at the top of the list and the farthest at the bottom of
the list. The nearest is highlighted.
Find Waypoint Menu (left) Category Selection menu (center) and list of
the nearest restaurants (right).
4. If you wish, you could scroll ↑ ↓ here to select another restaurant,
but for now we will just accept the nearest one. Press ENT.
5. The POI information screen appears. (This is how you can use this
unit as a business phone directory!) If you wanted to navigate there,
you could press Enter, since the Go To waypoint command is highlighted. But we just want to see it on the map, so press → to FIND ON
MAP|ENT.

the result of a restaurant search.
7. To clear the search and return to the last main page display, press
EXIT repeatedly.
NOTE:
Search works from mapping and POI data loaded in the unit. If you do
not have a high-detailed custom map (containing POI data) for the area
you are searching loaded on the MMC, you may not find anything.
102
Set a Waypoint
A waypoint is an electronic address based on the latitude and longitude
of a position on the earth. It represents a location, spot, or destination
that can be stored in memory, then recalled and used later on for navigation purposes.
You can create a waypoint at the cursor position on the map, or at your
current position while you are navigating. You can create a waypoint at
any location by manually entering the position's latitude and longitude.
You can copy waypoints from your unit to your personal computer with
MapCreate software. When you want to repeat a trip, these archived
waypoints can be reloaded into your GPS unit.
To create and save a Waypoint:
These first two techniques use the Quick Save method, the fastest and
easiest way to create a waypoint.
Create Waypoint at Current Position
While you are traveling, press WPT|WPT. The waypoint is saved and
automatically given a name with a sequential number, such as waypoint 003. The waypoint symbol and number appear on the map.
NOTE:
The Quick Save method uses the default waypoint symbol until you
edit an existing waypoint and change its symbol After you have
changed a waypoint symbol, the unit will remember the one you
chose and use it the next time you quick save a waypoint. To revert
to the default symbol, edit a waypoint and choose the original symbol or use the Reset Options command.

4. Press ↓ to LONGITUDE|ENT. Enter the longitude by pressing ↑ ↓ to
change the first character, then press → to the next character and repeat
until the longitude is correct. Press ENT, then EXIT|EXIT to return to the
previous page display. The waypoint is saved and automatically given a
name with a sequential number, such as "waypoint 001." The waypoint
symbol and number appear on the map and in the waypoint list.
Navigate To a Waypoint
You can select any waypoint visible on the Map Page with the cursor,
then use the Navigate to Cursor command (we'll describe how later in
this section.) However, you can avoid scrolling the map to pick your
waypoint if you use the Find Waypoint commands:
1. Press WPT|↑ to MY WAYPOINTS|ENT. To look up the nearest waypoint,
press ↓ to NEAREST|ENT; or to look by name, press ENT. For this example, let's look by name.
2. If your waypoint list is a long one, you can spell out the waypoint name
in the FIND BY NAME box. (Press ↑ ↓ to change the first character, then press
→ to move the cursor to the next character and repeat until the name is
correct, then press ENT to jump to the list below.)
3. If the list is short, you can jump directly to the FIND IN LIST box by
pressing ENT. Use ↑ ↓ to select the waypoint name, press ENT and the
waypoint information screen appears with the GO TO command selected.

Set Man Overboard (MOB) Waypoint
One of boating's most terrifying events is having a friend or family
member fall overboard. It's particularly dangerous at night or if you're
out of sight of land.
This unit has a man overboard feature that shows navigation data to
the location where the feature was activated. To activate it, press the
ZOUT and ZIN keys at the same time. Your position at the time these
keys are pressed is used as the man overboard position.
Caution:
Saving a new "Man Overboard" waypoint will overwrite and
erase the previous "Man Overboard" waypoint.
Navigate Back to MOB Waypoint
Find your way back to the accident position with the Navigation Page
or Map Page. When MOB is activated, the Navigation Page automatically shows the compass rose with its bearing arrow pointing toward
the man overboard position, and the destination name says "Going To
Man Overboard." The Map Page displays a Man Overboard waypoint,
represented by a human figure, and the steering arrow points where to
steer to reach that position.
Navigating to Man Overboard: "Man Overboard activated" message
(left). The Navigation Page (center) and Map Page (right). The victim is
astern of the vessel .GPS shows direction to steer to for the rescue.
The man overboard position is also stored in the waypoint list for future
reference. It can be edited the same as any other waypoint. This prevents the inadvertent loss of the current Man Overboard position.
To cancel navigation to MOB, press MENU|MENU|↓ to CANCEL NAVIGAto YES|ENT. The unit stops showing navigation information.

Navigate to Cursor Position on Map
The GO TO CURSOR command: navigates to the current cursor position on
the map. It's a quick and handy way to navigate to anything you can
see on the map display.
1. Use the cursor (controlled by the arrow keys) with the zoom in and
zoom out keys to maneuver around the map until you find a location
you want to go to.
2. Center the cursor over the location to select it. See the example in
the following figure. (Many map items such as waypoints, Points of Interest, towns, etc. can be "selected," and appear "highlighted" with a
pop-up box. Other features, such as a river or a street intersection will
not appear "highlighted," but the cursor will take you to those locations
just the same.)
In this example (left) cursor crosshairs are centered on Oologah,
Oklahoma. GPS menu with Go To Cursor selected (right).
3. Press MENU|ENT and the unit will begin navigating to the cursor location.
The Map Page will display a red line from your current position to the cursor position. The Navigation Page displays a compass rose showing navigation information to your destination. See the following examples.
107
The 30-mile zoom figure (left) clearly shows the red course line connecting
your current position to your destination. The second figure (center)
shows current position and direction to the destination. The Navigation
Page (right) will also show navigation information.
To stop navigating to the cursor, use the Cancel Navigation command:
press MENU|MENU|↓ to CANCEL NAVIGATION|ENT|← to YES|ENT. The unit
stops showing navigation information.
Navigate to a Point of Interest
For POIs that are in view on the map, you can easily use the Navigate
to Cursor command above; just use the cursor to select the POI.
The other method involves searching for POIs with the Find Waypoint
command, launched with the WPT key. (See the searching example earlier in this section or turn to Sec. 9, Searching, for detailed instructions
on POI searches.)
After you have looked up an item with the Find Waypoint command,
use ← → to make sure the GO TO command is highlighted at the bottom
of the screen, then press ENT. The unit shows navigation information to
the item.
To cancel navigation, press MENU|MENU|↓ to CANCEL NAVIGATION|ENT|←
to YES|ENT. The unit stops showing navigation information.
Creating and Saving a Trail
A trail, or plot trail, is a string of position points plotted by the unit as you
travel. It's a travel history, a record of the path you have taken. Trails are
useful for repeating a journey along the same track. They are particularly
handy when you are trying to retrace your trip and go back the way you
came. On the screen, trails are represented by a solid line extending from
the back of the current position arrow. The default color is light magenta.
The unit is set at the factory to automatically create and record a trail
while the unit is turned on. The unit will continue recording the trail
until the length reaches the maximum trail point setting (default is
108
2,000, but the unit can record trails 9,999 points long). When the point
limit is reached, the unit begins recording the trail over itself.
With the default auto setting, this unit creates a trail by placing a dot
(trail point) on the screen every time you change directions. (The methods
used for creating a trail and the trail update rate can both be adjusted or
even turned off. See Sec. 8 for Trail Options.)
To preserve a trail from point A to point B, you must "turn off" the trail
by making it inactive before heading to point C or even back to point A.
When the current trail is set inactive, the unit automatically creates
and begins recording a new trail.
To Save a Trail
1. Press MENU|MENU|↓ to MY TRAILS|ENT.
Visible

Active
symbol
Sequence for saving a trail and beginning a new one. My Trails command (left). The Trails Menu (center). The arrow to the right of Trail 3
indicates the trail is "active" and the check to the left indicates the
trail is visible on the map display. The third figure (right) shows the
Edit Trail menu, with the Name command selected.
2. Press ↓ to the Active Trail Name|ENT.
3. Press ↓ to ACTIVE|ENT. This unchecks the Active option.
4. To return to the main page display, press EXIT repeatedly.
As you leave the Edit Trail menu, you will notice that a new trail starts
with a new sequential number. In the example figure below, the new
trail is number 4, showing zero points. Note that Trail 3 is inactive, but
it is still visible on the map.
109
New trail, named "Trail 4," is created when Trail 3 is made inactive.
Any new travel will be recorded in this trail, which is active and visible. Trails do not need to be visible in order to be active.
You can save and recall up to 10 different plot trails, which can also be
copied to your MMC for archiving or for transfer to your MapCreate
software.
Tip:
Another quick way to stop recording one trail and begin a new one
is to use the New Trail command: Press MENU|MENU|↓ to MY
TRAILS|ENT|ENT.
Caution:
You also have the option of completely turning off trail recording, under the trail Options command. However, if the Update
Active Trail option is left turned off, it will cancel the automatic
trail creation feature.
Displaying a Saved Trail
The active trail is automatically displayed on the map (the "Visible"
option) with the factory default settings. You can selectively turn trail
display off and on for any saved or active trail. In the Saved Trails List,
visible trails have a check mark in front of the trail name.
To turn off trail display:
1. Press MENU|MENU|↓ to MY TRAILS|ENT.
2. Press ↓ to select the desired Trail Name from the Saved Trails List.
Press ENT.
3. Press ↓ to VISIBLE|ENT. To return to the main page display, press EXIT
repeatedly.

Navigating Trails
There are three methods for following a trail: visual trailing, navigating
a trail (forward) and backtracking a trail (backward). Try each method
to see which you prefer.
Visual trailing is the simplest method. It uses only the Map Page and
requires no menu commands at all. The technique works the same if
you are running a trail forward (from start to end) or backward (from
end to start.) However, visual trailing provides no navigation information during the trip, such as the time to your destination.
The other two methods provide a full range of navigation data and work
with both the Map Page and Navigation Page. The only difference between them is "navigating a trail" follows a trail forward (from start to
end) while "backtracking" follows a trail in reverse (from end to start.)
When hiking at walking speed with a hand-held GPS, we often just use
visual back trailing because it is a bit better at following each little
turn on a foot path. At faster speeds, such as the highway or on the water, the Navigate Trail and Backtrack Trail commands are handy.
Visual Trailing
1. On the Map Page, zoom (ZIN or ZOUT) so your trail is visible.
2. Begin moving and watch the Map Page. Walk or steer so your current position arrow traces along the trail you made.
Tip:
Generally, when using this method, the smaller the zoom range, the
more accurately you will be able to steer along the trail.
Navigate a Trail
The following figures illustrate the menu sequence for navigating a trail.
1. Press MENU|MENU|↓ to MY TRAILS|ENT.
2. Press ↓ to enter the Saved Trail list, then use ↑ ↓ to select the desired Trail Name|ENT.
3. Press ↓ → to NAVIGATE|ENT|ENT.

NOTE:
If you are located at or near the beginning of the trail, the arrival
alarm will go off when you hit Enter. Press EXIT to clear the alarm.
5. Now begin moving and let your unit guide you.
6. When you reach your destination, cancel navigation: press

Transfer Custom Maps and GPS Data Files
Custom Maps:
Custom maps work only from the MMC card or SD card. When a card
containing a Custom Map File is loaded into the unit, the unit automatically loads the map into memory when the unit is turned on.
Instructions for copying Custom Map Files to an MMC are contained in
the instruction manual for your MMC card reader and MapCreate 6
software. For instructions on inserting an MMC into the unit, see Sec.
2, Installation/Accessories.
GPS Data files:
GPS Data Files contain waypoints, routes, trails and event marker
icons. Instructions for copying GPS Data Files between your computer
and an MMC are contained in the instruction manual for your MMC
card reader and MapCreate 6 software.
GPS data automatically recorded in the unit's internal memory must be
saved to the MMC (as a GPS Data File) in order to store it on your personal computer. GPS Data Files stored on an MMC must be copied from

called later for navigation purposes. These are sometimes referred to as
event marker icons. This unit has 42 different symbols you can pick
from when creating an icon.
Icons are similar to waypoints, but they do not store as much information (like names) as waypoints do. You can't use a menu to navigate to
icons as you can with waypoints. (But, you can use the map cursor and
navigate to any icon on the map.)

Routes
A route is a series of waypoints, linked together in an ordered sequence,
that's used to mark a course of travel. You can visualize a route as a
string of beads. The beads represent waypoints and the string represents the course of travel connecting waypoint to waypoint.
The course from one waypoint to the next is a leg; routes are composed
of one or more legs. The legs of all GPS routes are based on straight
lines between waypoints.
A route provides the automatic capability to navigate through several
waypoints without having to reprogram the unit after arriving at each
119
waypoint. Once programmed into the GPS unit, a route provides the
option of navigating forward through the route waypoints or in reverse
order (you can even begin navigating in the middle of a route!)
Create and Save a Route
You have the option of creating and editing a route in the unit, or you
can make a route on your computer with our MapCreate 6 software.
PC-created Routes
MapCreate is the easiest method for preparing a route, because your
PC's larger screen, keyboard and mouse are easier to manipulate than
the unit.
To load a MapCreate route into the unit, follow instructions in MapCreate's manual for creating a route and saving it as part of a GPS Data File

Section 8: System & GPS Setup Options
Alarms
This unit has several GPS alarms. The factory default setting has all of
these but the anchor alarm turned on. You can turn the alarms off and
on and change their distance settings.
You can set an arrival alarm to flash a warning message and sound a
tone when you cross a preset distance from a waypoint. For example, if
you have the arrival alarm set to .1 mile, then the alarm will flash a
message when you come within .1 mile of the recalled waypoint.
The off course alarm warns you when your track drifts too far to the
right or left of the course line to the waypoint. For example, if the
alarm is set to .1 mile, then the alarm flashes a message if you drift .1
of a mile or more to the right or left of the line to the waypoint.
The anchor alarm is triggered when you drift outside of a preset radius.
Again, using the .1 mile as an example, if you're anchored and your
boat moves more than .1 of a mile, the alarm will flash a message and
sound a tone.

To get to Coordinate System Selection:
1. Press MENU|MENU|↓ to GPS SETUP|ENT.
2. Press ↓ to COORDINATE SYSTEM|ENT.
This unit can show a position in degrees (36.14952°); degrees, minutes
and thousandths of a minute (36° 28.700'); or degrees, minutes, seconds
and tenths of a second (36° 28' 40.9"). It can also show position in: UTM
(Universal Transverse Mercator) projection; MGRS (Standard); MGRS
(Standard + 10); Map Fix; Loran TD; British, Irish, Finnish, German,
New Zealand, Swedish, Swiss, Taiwan and Greek grid systems.
UTM's are marked on USGS topographic charts. This system divides
the Earth into 60 zones, each 6 degrees wide in longitude.
134
British, Irish, Finnish, German, New Zealand, Swedish, Swiss, Taiwan,
and Greek grid systems are the national coordinate system used only in
their respective countries. In order to use these grid systems, you must
be in the respective country. This unit will pick the matching datum for
you when you select the grid. See the entry on Map Datum Selection for
more information.
The Military Grid Reference System (MGRS) uses two grid lettering
schemes, which are referred to as standard and standard + 10 MGRS
on this unit. Your position and datum in use determines which one to
use. If you use standard, and your position is off significantly, then try
the alternate.
NOTE:
When the position format is changed, it affects the way all positions
are shown on all screens. This includes waypoints.
To change the coordinate system, press ENT while COORDINATE SYSTEM is
highlighted. Press the ↑ ↓ to highlight the desired format. Press ENT to
select it. Press EXIT to close the menus.
To setup Loran TD:
NOTE:
If the Loran TD conversion is chosen, you must enter the local Loran chain identification for the master and slaves. Do this by selecting "Setup Loran TD" at the bottom of the "Coordinate System"
menu and select the ID. Press EXIT to close this menu.
Configure Loran TD menu.
Map Fix
Map Fix is used with charts or maps. This system asks for a reference
position in latitude/longitude, which you take from a marked location
135
on the map. It then shows the present position as distance on the map
from that reference point.
For example, if it shows a distance of UP 4.00" and LEFT 0.50", you
then measure up four inches and to the left a half-inch from the reference point on the map to find your location.
To configure a map fix:
To use this format, you need to follow these steps in order. First, take
your map of the area and determine a reference latitude/longitude.
(Note: in order for this system to work, the latitude/longitude lines
must be parallel with the edge of the map. USGS maps are parallel,
others may not be. Also, this works better with smaller scale maps,
such as 1:24000.) The reference position can be anywhere on the map,
but the closer it is to your location, the smaller the numbers will be
that you'll have to deal with.
Once you've decided on a reference position, you can save it as a waypoint.
See the waypoint section for information on saving a waypoint. Save the
reference position as a waypoint. Exit the waypoint screens.
1. Press MENU|MENU|↓ to GPS SETUP|ENT.
2. Press ↓ to COORDINATE SYSTEM|ENT.
3. Press ↓ to SETUP MAP FIX|ENT.
The screen below appears, and MAP SCALE is highlighted. Press ENT and
enter the map's scale. This is generally at the bottom of the paper map.
It's shown as a ratio, for example 1:24000. Press EXIT and the unit returns to the Configure Map Fix screen.
Configure a map fix so the unit can find your position on a printed
chart or topographical map.
Press → to SELECT ORIGIN|ENT to bring up the waypoint and POI list.
Select the waypoint (or a landmark of POI) that you saved the reference
136
point under and press ENT. The unit displays a waypoint information
screen with the command SET AS ORIGIN selected; press ENT and the unit
returns to the Configure Map Fix menu. Finally, press EXIT to close this
menu. Now press ↑ to COORD SYSTEM|ENT, select MAP FIX from the list and
press ENT. Press EXIT repeatedly to get back the main page display. All
position information shows as a distance from the reference point.
Customize Page Displays
Every display option with digital data boxes can be customized. The
data available in your unit is divided into categories in the Data Viewer
menu. These categories include GPS Data, Navigation, Trip Calculator,
Time, and Sonar Data. You can select items from any of these categories for display in any data box — the category divisions are only there
to help you sort through the information.
To change the information displayed in a data box:

Simulating Trail or Route Navigation
In Simulator mode, your unit can automatically follow a trail or route
without manual steering if you use these steps:
1. From the Map Page, go to the simulator menu. Pick a STARTING POSITION at or near the beginning of your trail/route. Enter an approximate
TRACK (shown in compass degrees) that will point you toward the start
of the trail/route.
2. Set SPEED to zero. Select STEER WITH ARROWS command and press ENT,
which turns on the simulator and returns you to the Map Page.
3. Begin navigating along the trail/route. (If you are close enough to the
first waypoint, the arrival alarm will usually go off as soon as navigation begins. Press EXIT to clear the alarm.) When navigation starts,
press ↑ to increase speed to the desired setting.
4. Press EXIT to turn off the steering and speed boxes. The unit will now
automatically "steer" along the trail or route. When you arrive at your
"destination," cancel navigation as you normally do.
Tip:
You can pick any spot on the map to begin your simulation session
by using the Initialize GPS command. This makes your unit think
it's located at the position you select. See its entry following the entry for Hide GPS Features.

that divide the plotter into equal segments of latitude and longitude.
Range rings are handy for visually estimating distances on the map. The
ring diameters are based on the current zoom range. For example: at the
100 mile zoom, the screen will show two rings with your current position
in the center. The large ring touching the left and right sides of the
screen is 100 miles in diameter (same as the zoom range). The second
smaller ring is 50 miles in diameter (always 1/2 the zoom range).
The distance from your current position to the smaller ring (the ring's
radius) is 25 miles (always 1/4 the zoom range). With the arrow keys
and map cursor, you can scroll the map to see the third and fourth
rings. In this example, the distance to the third ring is 75 miles and
distance to the fourth ring is 100 miles from your current position.

Map Datum Selection
Maps and charts are based on a survey of the area that's covered by the
map or chart. These surveys are called Datums. Maps that are created
using different datums will show the same latitude/longitude in slightly
different locations.
All datums are named. The GPS system is based on the WGS-84 datum, which covers the entire world. Other datums may also cover the
entire world, or just a small portion of it. By default, your position
shows using the WGS-84 datum. However, it can show your position
using one of 191 different datums. Different datums can be selected; to
change the datum:
1. Press MENU|MENU|↓ to GPS SETUP|ENT|↓ to DATUM SELECTION|ENT.
2. Use ↓ ↑ to select the desired datum and press ENT.

Map Orientation
By default, this receiver shows the map with north always at the top of
the screen. This is the way most maps and charts are printed on paper.
In Track Up mode, map shows "N" and arrow to indicate north.
The first figure (left) is shown in north up and the second figure (right)
is in track up.
This is fine if you're always traveling due north. What you see to your
left corresponds to the left side of the map, to your right is shown on
143
the right side of the map, and so on. However, if you travel any other
direction, the map doesn't line up with your view of the world.
To correct this problem, a track-up mode rotates the map as you turn.
Thus, what you see on the left side of the screen should always be to
your left, and so on.
Another option is course-up mode, which keeps the map at the same
orientation as the initial bearing to the waypoint. When either the
track-up or course-up mode is on, an "N" shows on the map screen to
help you see which direction is north.
To change map orientation: from the Map Page, press MENU|↓ to MAP

Section 9: Searching
NOTE:
The background map loaded in your unit lets you search for U.S.
Interstate Highway exits and exit services, as well as some land
features, including cities and lakes. For a full set of searchable land
features, including landmarks, streets, addresses and Points of Interest, you must load your own high-detail custom map produced
with our MapCreate 6 software. For a complete description of what
detail is found in the background map and custom MapCreate
maps, see page 93. (Remember, our pre-made FreedomMaps contain all the same detail found in custom-made MapCreate maps.)
