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 GPSequipped 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 water, fast!
Welcome to the exciting world of digital sonar and GPS! We know
you're anxious to begin 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 combination fish finder and GPS receiver.
First, we want to thank you for buying a Eagle sonar/GPS unit.
Whether you're 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.
Our goal for this book is to get you on the water fast, with a minimum
of fuss. Like you, we'd 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 8 sections. This first section is an introduction to the Cuda™ 350 sonar and GPS. It tells you the basics you
need to know before you can make the unit look below the surface to
find some fish.
Section 2 will help you install your unit, as well as the transducer (the
most important part of any sonar installation). 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 sonar, right out of the box.
1
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 50 and head for the water with your unit!)
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, looking it
up in the manual's index, just flipping through Section 3 or scanning
through the sonar setup options in Section 7.
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 99.
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.
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 or index, just
flipping through Section 6 or scanning through the setup options in
Section 7.
This unit is ready to use right out of the box, but you can fine tune and
customize its operation with dozens of options. Since sonar is the unit's
key feature, we put the main sonar options in Section 3. 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 7, System Setup and GPS Setup Options. Section 7 is
organized in alphabetical order.
Finally, in Section 8, we offer Supplemental Material, including warranties and customer service information, and a handy index.
Now, if you're into the fine details, glance over the next segment on specifications to see just how much sonar and GPS power your unit contains.

It's important to us (and our power users), but, if you don't care how
many watts of power the unit has, or how many waypoints it can store,
skip ahead to important information on how sonar works, on page 5.

How Your 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 underwater 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. In
simple terms, here's how it finds the bottom, or the 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
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 sonar unit can record a log of the sonar signals that scroll across the
screen and save them in its memory. (These recordings are also called
sonar charts or sonar graphs.)
5
You can replay this sonar log in the unit using the Sonar Simulator function. You can save several different sonar log files, erase 'em and record
new ones, over and over again.
How Your GPS Works
You'll navigate faster and easier if you understand how this 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, and you can
later impress your friends with your new-found knowledge.)
First, think of your unit as a small but powerful computer. (But don't
worry — we made this unit easy to use, so you don't need to be a computer expert to find your way!) 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 GPS plotter, as well as point the way to your
destination.
This unit uses an internal antenna/receiver module, which makes the
whole system work something 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 in to the WAAS satellites
in orbit, but more about that in the upcoming 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 it figures its latitude and
longitude, the unit plots that position on the GPS screen. The whole
process takes place several times a second!
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, and retrace
your path.
6
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.
Introduction to GPS and WAAS
Well, now you know the basics of how the unit does its work. You might
be ready to jump ahead to Section 2, Installation, on page 13, 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 9. 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.
7
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.
Three satellites are required to determine a 2D fix.
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 doesn’t 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 the 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 plenty accurate for route navigation, but the U.S. Federal
Aviation Administration has special aircraft navigation needs that go
8
beyond basic GPS. So, the FAA has developed a program to boost GPS
performance with its Wide Area Augmentation System, or 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 it consistently delivers accuracies within 1-2 meters
horizontal and 2-3 meters vertical, according to the FAA. It does this by
broadcasting correction signals on GPS frequencies. Your unit automatically receives both GPS and WAAS signals.
There, however, are 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 man-made
structures can sometimes block the WAAS signal from ground receivers.
You will find that using your GPS receiver is both easy and amazingly
accurate. It is easily the most accurate method of electronic navigation
available to the general public today. Remember, however, 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
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 are in a real hurry, you
9
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
plotter 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 this 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 Plotter 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.
10
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
Plotter 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 and then the down arrow key to highlight the Navigate command,
then press Enter."

Section 2: Installation
Preparations
You can install the sonar and GPS systems 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 vehicle or vessel!
1. Determine the approximate location for the sonar/GPS unit, so you
can plan how and where to route the power/transducer cable. This will
help you make sure you have enough cable length for the desired configuration.
2. Determine the approximate location for the transducer and its cable
route.
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/GPS 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 to the unit and mount the sonar/GPS unit to the bracket.
Transducer Installation
These instructions will help you install your Skimmer® transducer on a
transom, on a trolling motor or inside a hull. Please read all instructions before proceeding with any installation.
13
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.
Read these instructions carefully before attempting the installation.
Determine which of the installation methods is right for your boat.
Remember, the transducer location and installation 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.
NOTE:
The following installation types also call for these recommended
tools and required supplies that you must provide (supplies listed
here are not included):
Transom installation
Tools include: two adjustable wrenches, drill, #29 (0.136") drill bit, flathead screwdriver. Supplies: high quality, marine grade above- or belowwaterline sealant/adhesive compound.
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
14
sandpaper, specially formulated epoxy adhesive available from LEI (see
ordering information on the inside 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 as random lines or dots when the boat is moving.
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°

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) from the propeller.
15
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.

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.
16
Transom
Transducer
centerline
Hull bottom
Align transducer centerline with hull bottom.
However, there 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 actually 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 direct contact with
the water.
17
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.
However, 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 lesson to determine if you can satisfactorily
shoot through the hull.
TRANSOM TRANSDUCER ASSEMBLY AND MOUNTING
The best way to install the transducer 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.
1. Assembling the 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.
18
Dot
Align plastic ratchets in bracket.
2. Aligning the transducer on the transom. 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 3. If it doesn't,
repeat step 2, but use a different alignment letter until you can place
the transducer on the transom correctly.
19
Ratchets
Insert bolt and check transducer position on transom.
3. Assembling the transducer. 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.

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!
20
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 using the #29 bit (for the #10 screws).

5. Attaching transducer to transom. Remove the transducer from
the bracket and re-assemble it with the cable passing through the
bracket over the bolt as shown in the following figures.
Route cable over bolt and through bracket. Side view (left) and seen
from above (right).
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/adhesive compound.
21
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.
Bottom

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 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 seal22
ant/adhesive 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
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.)
Bolt

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.
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.
23

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.
25
SHOOT-THRU-HULL PREPARATION
Hulls With Floatation 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
Fill with
Flotation material
Inner hull
Epoxy to hull first
Outer hull
Use epoxy to place the transducer in 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
26
air bubbles in the fiberglass or the epoxy will reduce or eliminate 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.
Transducer location

Transducer location
(high speed)
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.
27
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 page 30.) Notice how the signal strength decreases. 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.
28
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 26.
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
30
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. 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.
Power and Cable 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.
32
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.
Mounting the Sonar Unit: In-Dash or Bracket
You can install the sonar unit on the top of a dash with the supplied
bracket. It can also be installed in the dash with an optional FM-6
dash-mounting kit.

33
Bracket Installation
Mount the unit in any convenient location, provided there is clearance
when it’s tilted for the best viewing angle. You should also make sure
there is enough room behind the unit to attach the power/transducer
cable. (See the following drawings, which show the dimensions of a
mounted Cuda 350 sonar unit.)
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 panels to reinforce the panel and secure the mounting hardware.
Drill a 5/8" (15.9 mm) hole in the dash for the power/transducer cable.
The best location for this hole is immediately under the mounting
bracket location. This way, the bracket can be installed so that it covers
the hole, holds the cable in position and results in a neat installation.
Some customers, however, prefer to mount the bracket to the side of
the cable hole — it's a matter of personal preference. After drilling the
hole, pass the connector up through the hole from under the dash.

If you wish, you can fill in the hole around the cable with a good marine
sealant compound. (Some marine dealers stock cable hole covers to conceal the opening.)
This unit uses a quick release-mounting bracket. When you run the
cable through the hole, make sure you allow enough slack for tilting the
unit and attaching the connector. (The snug fit of the push-on waterproof connector requires some force to attach.) Also be sure there is
enough cable slack for rotation if you decide to use the optional GBSA-3
swivel base. The swivel base lets you rotate the sonar so it can be seen
from different parts of the boat.

Portable Sonar Installation
Like many Eagle products, the Cuda 350 sonar is capable of portable
operation. It uses the optional PPP-12 portable power pack.
The power pack and portable transducers expand the uses for your sonar. You can use your Cuda 350 sonar 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. (An alternative to the PPP-12 is the PPP-15
portable power pack, which was designed especially for ice fishing. It
includes a rechargeable gel cell battery and a transducer designed for
stationary use. The entire rig is contained in a carry bag that fits inside
a five-gallon plastic bucket.)
The PPP-12 package includes the power pack, battery adapter and a portable transducer. The transducer can be stored inside the power pack. The
PPP-12 requires eight AA alkaline batteries. Batteries are not included.
To use a portable power pack, you install the batteries and then attach
the sonar unit to the power pack's bracket. Plug in the
power/transducer cable and you're ready to fish.
The PPP-12 has a quick-release mounting bracket built into the case.
Installing the Batteries
Release the latch on the front of the power pack case. Open the compartment and install eight AA batteries into the adapter. For the longest life, we recommend you use alkaline batteries.
NOTE:
When the unit is not in use, we recommend you unplug the power
connector to reduce the possibility of corrosion or battery drain.
When you store the unit, always remove the batteries because dead
batteries can leak and corrode the contacts.
After installing the batteries, plug the cable's power connector into the
socket on the battery compartment cover. Route the cable's unit con38
nector and about 6 inches of cable through the opening under the sonar
mount. Close the cover, plug the connector into the sonar unit and
mount the unit on the built-in bracket.
PPP-12 Portable Power Pack with a sonar unit stowed for transport.
Turn the unit on. If it doesn't work, make sure the battery terminals
are making good contact against the battery contacts. Also check the
wiring connections on the battery adapter. The red wire on the power
cable should be attached to the red wire on the battery adapter and the
power cable's black wire should be connected to the black wire on the
battery adapter.
If it still doesn't work, check the battery voltage. Most of the complaints
we receive about portable units result from stale batteries. Make sure
the ones you buy are fresh.
In cold weather the efficiency of dry cell batteries drops with the temperature. We find it a good idea to have the sonar unit good and warm
along with the batteries before we leave home.
39
If the batteries do lose a charge, you can sometimes restore them by
placing them in a warm room or car interior. A better way is to replace
them with batteries that have been kept warm.
WARNING:
Never heat the batteries over an open flame or direct hot
air onto them. A fire or explosion could result.
Portable Transducer Assembly
Recommended tools for installation include a slotted screw driver and
two adjustable wrenches.
Assemble the transducer and bracket as shown in the following figure.
Attach the transducer to the bracket with the supplied hardware.
Make sure there is one washer on each side of the transducer, inside
the bracket. Slide the other washer over the end of the bolt and thread
the nut onto it.
Screw the suction cup onto the bracket using the supplied screw and flat
washer. Tie the nylon cord through the hole in the top of the bracket.
When using this transducer, tie the other end of the nylon cord to the
boat. This will help prevent the loss of the transducer if it comes off the
boat.

You can customize how the Sonar Page pictures and other data are displayed in many ways. We will discuss all of those features and options in
the Advanced Sonar Operation section, but to show you how easy the sonar 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.
49
Sonar Quick Reference
1. Mount the transducer and unit. Connect the unit to electric power
and the transducer.
2. Launch your boat.
3. To turn on the unit, press and release PWR key.
4. Head for your fishing area. Your unit automatically displays digital
depth and surface water temperature in the corner of the screen.
5. As you watch the sonar returns, 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.
6. If necessary, adjust sensitivity to improve chart readability. Press
MENU|ENT and the Sensitivity Menu will appear on the left of your
screen. Use ↑ and ↓ to change the setting.
7. Watch the display for the appearance of fish arches. When you see
arches, you have found fish!
8. Gauge the fish depth by visually comparing the fish 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 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 the unit to return a 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.
10. To turn off the unit, press and hold PWR key for three seconds.
50
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 it.
As you are 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. There are times when
too much clutter appears on the screen. Decreasing sensitivity will 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.

These figures show results of different sensitivity levels on the same
location. Fig. 1: Sensitivity at 87 percent, determined by Auto Sensitivity. Typical of full auto mode. Fig. 2: Sensitivity set at 50 percent. Fig.
3: Sensitivity set at 20 percent. Fig. 4: Sensitivity set at 100 percent.
You can change the sensitivity level whether you are in Auto or Manual Sensitivity mode. The adjustment procedure works the same in
both modes, but gives you slightly different results.
52
Adjusting sensitivity in Auto Sensitivity Mode is similar to manually adjusting a car's speed 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 this sonar
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 control of the car's
speed. In the sonar unit, manual mode allows you to set sensitivity at
to the maximum or minimum settings. 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. Press ↓ to decrease sensitivity.
Press ↑ to increase sensitivity. When it is set at a desired level, press
EXIT. If you reach the maximum or minimum limit, a tone will sound.

NOTE:
If you want to change the sensitivity in Manual Mode, turn off Auto
Sensitivity. From the Sonar Page, press MENU|↓ to AUTO SENSITIVITY|ENT|↑ to SENSITIVITY|ENT. Press ↓ or ↑ 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 the screen. If
that happens, remember it is easy to switch back to full automatic
operation by restoring the factory default settings.
To Restore Factory Settings
1. Press MENU|MENU|↓ to SYSTEM SETUP|ENT|↓ to RESET OPTIONS|ENT.
2. A reset options confirmation message will appear. Select YES and
press ENT. All options are reset and the unit reverts back to the
original settings.
54
Fish Symbols vs. Full Sonar Chart
You may have noticed in the quick reference we used fish arches in full
sonar chart mode for our example and not the popular Fish I.D.™ fish
symbol feature. Here is why.
Fish I.D. is an easier way for a sonar novice to recognize a fishy signal
return when he sees it. But 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 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 are in another part of the boat or performing a task that prevents you from watching the sonar screen.
While in Fish I.D. mode, you can turn on the audible fish alarm, so
when a fish swims under your boat, you will hear it!
Fish I.D. can also be useful when you want to screen out some of the
sonar detail. In one case, a fishermen in San Francisco Bay saw clouds
of clutter in the water but no fish arches. When a downrigger was
pulled up, it brought up several small jellyfish. The fishermen switched
his sonar to Fish I.D., which screened out the schools of jellyfish and
clearly showed game fish as fish symbols.

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 feature automatically 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 like bilge pumps, engine vibration, ignition systems, wiring and
air bubbles passing over the face of the transducer. 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. If, however,
you are having trouble with noise, we suggest you take steps to find the
interference source and fix it rather than continually using the unit
with a 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.
57
Sonar Features selected (left). In the Sonar Features menu, Noise Rejection is selected with ASP in the default low setting (right).
To change the ASP level:
1. From the Sonar Page, press MENU|↓ to SONAR FEATURES|ENT.
2. Press ↓ to NOISE REJECTION|ENT.
3. Press ↓ or ↑ to select a setting, then press ENT.
4. To return to the previous page, press EXIT|EXIT.
Alarms
This unit has three different types of sonar alarms. The first is a Fish
Alarm. It sounds when the Fish I.D.™ feature determines an echo is a
fish.
Another alarm is the Zone Alarm, which consists of a bar on the side of the
screen. Echoes that appear inside the range of the bar trigger the alarm.
The last alarm setting is the Depth Alarm, which has both a Shallow
and a Deep setting. Only the bottom signal will trigger this alarm. This
is useful anchor alert, 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 set58
ting. 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.

61
Chart Speed
The rate that echoes scroll across the screen is called the chart speed.
Maximum is the default. We recommend you leave the chart speed at
the default setting for most all fishing conditions. You, however, might
consider experimenting with chart speed when you are stationary or
drifting very slowly. You may achieve better fish signals when you decrease the chart speed until it matches your speed across the water.
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.

If you do experiment with chart speed, remember to reset it to maximum when you resume trolling or moving across the water at a higher
speed. To change chart speed:
1. From the Sonar Page, press MENU|↓ to CHART SPEED|ENT.
2. The Chart Speed Control Bar appears. Press ↓ to decrease chart
speed. Press ↑ to increase chart speed.

NOTE:
The sonar's depth capability depends on transducer installation,
water and bottom conditions, among other factors.
FasTrack™
This feature automatically converts all echoes to short horizontal lines
on the right side of the screen. 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 are fishing at anchor.

Fish I.D.™ (Fish Symbols & Depths)
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 undesirable signals. In most instances,
65
remaining targets are fish. 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 can be fooled. It can
not 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 most difficult object for
Fish I.D. to distinguish from fish. You may see fish symbols on the
screen when actually, there are no fish. The reverse is also true.
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 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 with and without Fish I.D. mode to become more familiar
with the feature. The default for Fish I.D. is off.

Grayline®
Grayline lets you distinguish between strong and weak echoes. It
paints gray 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 gray line or no gray line at all. A hard bottom returns a strong signal, which causes a wide gray line.
If you have two signals of equal size, one with gray and the other without, then the target with gray is the stronger signal. This helps distinguish weeds from trees on the bottom, or fish from structure.
Grayline is adjustable. Experiment with your unit to find the Grayline
setting that's best for you.

Ping Speed & HyperScroll™
Ping Speed controls the rate at which the transmitter and transducer
broadcast sonar sound waves — pings — into the water. The unit has a
default ping speed of 50 percent. At normal boating speeds, this automatically provides enough return echoes to refresh the screen and
scroll the chart at maximum chart speed.
But 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.
70
The increased ping rate allows the screen refresh rate and chart scroll
speed to keep pace with the boat as it moves quickly over the water.
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.

EXIT.
To turn off HyperScroll:
1. From the Sonar Page, press MENU|↓ to PING SPEED|ENT.
2. The Ping Speed Control Bar appears. Press ↓ to decrease ping speed
to 50 percent. When it isset at the desired level, press EXIT.
71
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 it's entry in this section.
Reset Options
This command is used to reset all features, options and settings to the
factory defaults. This is useful when you have changed several settings
and want to return the unit to basic automatic operation.
1. Press MENU|MENU|↓ to SYSTEM SETUP| ENT|↓ to RESET OPTIONS|ENT.
2. A confirmation message will appear. Select YES and press ENT.
3. All the menus are cleared and all options return to factory settings.
System Menu with Reset Options command selected.
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.
72
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 Grayline 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.
Situations occur, however, 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 necessary or when wave
action and boat wakes create tiny air bubbles that clutter the water
column. In that case, a decrease in sensitivity is needed to reduce some
of the clutter.
In automatic mode you can adjust sensitivity up to 100 percent, but the
unit will limit your minimum setting. It 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 mode, the unit will continue to use that sensitivity setting until it is modified or until the unit is put back into auto mode.
To adjust sensitivity in auto mode:
1. Press MENU|ENT.
2. The Sensitivity Control Bar appears. Press ↓ to decrease sensitivity.
Press ↑ to increase sensitivity. When it is set at the desired level, press
EXIT. (When you reach the maximum or minimum limit, a tone sounds.)
Tip:
For quicker sensitivity adjustments, try leaving the Sensitivity
Control Bar on the screen as the chart scrolls. You can see the
73
changes on the screen as you press the up or down arrows. This is
handy when there is a lot of clutter in the water and you are matching the sensitivity to rapidly changing water conditions.

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 back to Auto and reset the factory setting at the same time.
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.
74
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 indicators: chart depth
scale, chart cursor depth and fish symbol depth displayed on the screen.
To calibrate the depth indicators, 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. We enter this as a negative 3.5 feet, which makes the depth indicators perform as if the transducer is lower in the water than it really is.
1. Press MENU|MENU|↓ to SONAR SETUP|ENT.
2. Select SET KEEL OFFSET and press ENT.
3. The Keel Offset dialog box appears. Press ↓ so the displayed number
shows a minus (–) sign instead of the plus (+) sign.
3. To change the next digit, press → then use ↑ ↓ to enter 3. Move to
the next digit and enter 5, then press EXIT. The depth indicators now
accurately show the depth of water beneath the keel as -3.5.
NOTE:
If knowing the exact depth of water beneath the keel is less important, you can 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 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.
75
1. Press MENU|MENU|↓ to SONAR SETUP|ENT.
2. Select SET KEEL OFFSET and press ENT.
3. The Keel Offset dialog box appears. Press ↓ so the displayed number
shows a plus (+) sign instead of the minus (–) sign.
3. To change the next digit, press → then use ↑ ↓ to enter 1. Move to
the next digit and enter 5, then press EXIT. The depth indicators now
accurately show the waterline as 1.5 feet above the transducer.
Sonar Color Mode
The default color scheme for the sonar chart is grayscale, but we offer
other variations to suit your viewing preferences. You can select the
chart to be displayed in reverse grayscale, bottom black or FishReveal

elsewhere in this section.)
To change the chart mode color scheme:
1. From the Sonar Page, press MENU|↓ to SONAR FEATURES|ENT.
2. Press ↓ to SONAR CHART MODE|ENT.
3. Press ↓ or ↑ to Mode Name|ENT.
4. Press EXIT|EXIT to return to the Sonar Page.
Sonar Page & Sonar Chart Display Options
The Cuda 350 offers three Sonar chart display options. To choose one,
press EXIT to clear any menus, then press PAGES and use the ↑ ↓ keys
to select the desired mode.
Full Sonar Chart
This is the default mode used when the Sonar is turned on for the first
time or when it is reset to the factory defaults. The bottom signal
scrolls across the screen from right to left. Depth scales on the right
side of the screen aid in determining depth of targets. The line at the
top of the screen represents the surface.
76
The bottom depth and surface temperature (if the unit is equipped with
a temperature sensor or a transducer with a temp sensor built in) show
at the top left corner of the screen.
The FasTrack™ display shows just to the right of the scale. This
changes all echoes into short horizontal bars, replicating a flasher sonar. The zoom bar on the far right shows the area that is zoomed when
the zoom is in use. (See the Zoom section for more information.)
Full Sonar Chart. The Overlay Data (depth and water temperature)
are set to a different text size.
Split Zoom Sonar Chart
A split chart shows the underwater world from the surface to the bottom on the right side of the screen. The left side shows an enlarged version of the right side. The zoom range shows at the bottom left corner of
the screen.
77
Split Zoom Sonar Chart. First image (left) shows the left window
zoomed to 2X. The second image (right) shows the left window zoomed

Sonar Simulator
This unit has a built-in simulator that will allow you to practice as
though you were on the water. All sonar features and functions will be
useable during a simulation. When in simulator mode, you will see
[Simulator Mode] in the Sonar Page title bar. To use the simulator:
1. From the Sonar Page, press MENU|MENU|↓ to SONAR SETUP|ENT.
2. Select SONAR SIMULATOR ON and press ENT. If you want to simulate your
position, highlight SIMULATE POSITION and press ENT, which will turn on
the GPS Simulator.
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 will play. 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. The simulator
will continue to function normally.
Stop Chart
If you are running multiple units on a boat, there are times when you
may want to turn off the sonar. This command turns off the sonar and
stops the chart from scrolling. Sonar restarts automatically each time
you turn on your unit.
Press MENU|↓ to STOP CHART|ENT|EXIT.
To turn the sonar on again, repeat the step above.
79
Sonar Menu with Stop Chart selected. The box is unchecked, indicating the chart is scrolling across the screen.
Surface Clarity
The onscreen marks scattered at the top of the sonar chart are known
as surface clutter. They are caused by wave action, boat 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 four levels of surface clarity available: off, low, medium or
high. The default level is off.
To adjust the Surface Clarity level:
1. From the Sonar Page, press MENU|↓ to SONAR FEATURES|ENT|ENT.
2. Press ↓ ↑ to select clarity level, then press EXIT repeatedly to get back
to the main page display.
80
Sonar Features menu with Surface Clarity selected.
Zoom & Zoom Bar
The Zoom in key is used to enlarge small detail, fish signals and the
bottom with its associated structure.
The 2X zoom doubles the size of all echoes on the screen. The 4X zoom
quadruples the size of the echoes. You can also turn on a zoom bar on
the far right side of the screen. This shows which echoes will be displayed on the screen when the Zoom commands are used.
For example, turning on the 2X zoom will show all echoes that are between the top and bottom of the 2X zoom bar. The 4X zoom will show
only the echoes between the top and bottom of the 4X zoom bar.
To switch the zoom:
1. Press ZIN to increase the zoom display to 2X. Press ZIN again for a 4X
zoom.
2. Press ZOUT to reduce the zoom and show more of the chart.
To turn on the Zoom Bar:
1. Press MENU|↓ to SONAR FEATURES|ENT.
2. The Sonar Features menu appears. Press ↓ to ZOOM
BAR|ENT|EXIT|EXIT.
3. To turn off the Zoom Bar, repeat steps 1 and 2.

2X (left). Sonar page with view zoomed to 4X (right)
Zoom Pan
Your unit has the ability to quickly 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, you can get a good,
close-up look at structure or cover below you.
To use Zoom Pan, switch to a manual depth Range setting (see page 49)
and turn on 2X or 4X Zoom. Then use the ↑ ↓ keys to pan up and down
the water column.
82
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 certain 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 11 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 operates only in demo mode:
The transducer or antenna module has not yet been connected or has
been disconnected. To leave demo mode, make sure that either the
transducer or the antenna is securely connected before turning the unit
on.
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 both the transducer and power connectors. Make certain both
83
are 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. Use only LEI epoxy.
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.
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 sig84
nals 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.
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)].
85
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 certain 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 for the best mounting position.

Pages Menu, showing Map display options.
90
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 that represent fish, structure and
the bottom. The Sonar Page is discussed in detail in Sec. 3. To get to
the Sonar Page press PAGES|→ to SONAR|EXIT.
Satellite Status Page
The Satellite Status GPS Page provides detailed information on the
status of the Cuda's satellite lock-on and position acquisition. To get to
the Satellite Status Page press PAGES|← to Map|↓ to SATELLITES|EXIT.
No matter what Page display you are on, a flashing current position
indicator/question mark symbol and flashing GPS data displays indicate satellite lock has been lost and no position has been acquired. 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!
Satellite Page. First page (left) indicates unit has not locked on to any
satellites and does not have a fix on its position. The second page (center) shows satellites being scanned. The last page (right) shows satellite lock-on with a 3D position.
91
The Satellite Page screen shows a graphical view of satellites the unit is
tracking. A 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 gray. The receiver has not locked onto a satellite if the number is black, therefore it
isn't being used to resolve 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.
The Estimated Position Error (horizontal position error) shown in the
upper right corner of the screen is the expected error from a benchmark
location. In other words, if the EPE 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.
The Satellite Status Page has its own menu, which is used for setting
various options. (Options and setup are discussed in Sec. 8.) 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 MAP|↑ ↓ to NAVIGATION|EXIT.
The navigation screen looks like the one below when you are 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 —path
92
you've just taken — is depicted by the line extending from the arrow.
The arrow pointing down at the top of the compass rose shows your current track (direction of travel).

this when the unit is not navigating to a waypoint, following
a route, or backtracking a trail.
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 Speed, Track and Position information displays
are flashing, satellite lock has not been acquired and no position fix
has been determined. A question mark will also flash on the present position arrow in the center of the compass rose.
93
Speed is the velocity you are making over the ground. If you wanted,
you could customize the Speed window to display Closing Speed instead. Closing Speed is also known as velocity made good.
It is the speed you are making toward the waypoint. Track is the heading or the current direction you are 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 are 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 dotted 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.
A circular symbol depicting your destination (waypoint) appears on the
screen when approach the waypoint, as shown on the screen in the following 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 window 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.

Full Map Page
The Full Map screen shows 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 do
not have to navigate to a waypoint to use the map. Full Map is the default screen that appears when you turn on the unit.
95
To get to the Full Map press PAGES|← to MAP|ENT. When the Map
Page is displayed, a screen similar to the following figures appears.
The arrow in the center of the screen is your position. It points in the
direction you are traveling. The flashing line extending from the back
of the arrow is your plot trail. The map zoom range is the distance
across the screen. This number shows in the lower right corner of the
screen. In the first example figure below, the range is 4,000 miles. 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.

12. To turn off the unit, press and hold PWR key for three seconds.
Find Your Current Position
Turn on the unit. It automatically searches for satellites and calculates
its position in approximately one minute or less, under clear sky conditions.
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 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.
99
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 cursor
crosshairs. 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.

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 crosshairs on the desired object. On most items, a pop-up box will give the name of the selected item.
Set a Waypoint
A waypoint is an electronic address, based on the latitude and longitude of a position on the earth. A waypoint represents a location, spot
or destination that can be stored in memory, then recalled later 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.
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.

WPT twice to call up Find Waypoint screen (seen in Step 2) and set a
point. Step 3: a message says the waypoint has been saved. Step 4: vehicle continues on its way; number waypoint symbol is visible on map.
NOTE:
The Quick Save method uses the default waypoint symbol until you
edit an existing waypoint and change its symbol. (Edit Waypoint
Symbol is described in Sec. 7.) 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 the waypoint or use the Reset Options.
102
Create Waypoint on Map
1. Use the arrow keys to move the cursor to the place where you want
to make a waypoint.
2. Press WPT|WPT. The waypoint is saved and automatically given a

Navigate To a Waypoint
You can select any waypoint visible on the Map Page with the cursor,
then use the Navigate to Cursor command. You, however, can avoid
scrolling the map to pick your waypoint if you use the Find Waypoint
commands:
1. Press WPT|→ to SAVED|ENT. To look up the nearest waypoint, press
ENT or to look by name press ↓| ENT. For this example, 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.
103
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.
4. To begin navigating to the waypoint, press ENT.
Find by Name highlighted (left). Find By Name menu (center). Waypoint information screen (right).
Set Man Overboard (MOB) Waypoint
One of boating's most terrifying events is having a friend or family
member fall overboard. It is particularly dangerous at night or if there
is no land in sight.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 automati104
cally 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 (left), Navigation Page (center), and Map Page (right). The victim is astern of the
vessel. The GPS shows which 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.
To cancel navigation to MOB, press MENU|MENU|↓ to CANCEL NAVIGATION|ENT|← to 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 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 crosshairs over the location to select it. See the
example in the following figure. Many map items such as waypoints,
marine NavAids, towns, etc. can be selected and appear highlighted
105
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, the cursor is centered on Oologah, Oklahoma.
3. Press MENU|ENT to begin navigating to the cursor location.
The Map Page will display a dotted 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.
The 30-mile zoom figure (left) clearly shows the dotted course line connecting your current position to your destination. The 30-mile zoom (center) shows both current position and direction to destination on screen.
The Navigation Page (right) will also show navigation information.
106
To stop navigating to the cursor, use the Cancel Navigation command:
press MENU|MENU|↓ to CANCEL NAVIGATION|ENT|← to YES|ENT. The
Cuda stops showing navigation information.
Navigate to a Map Place
For map places that are in view on the map, you can easily use the
Navigate to Cursor command above; just use the cursor to select the
map place.
The other method involves searching for map places with the Find
Waypoint command, launched with the WPT key. Turn to Sec. 9,
Searching, for detailed instructions on map place searches.
After you have looked up an item with the Find Waypoint command,
use the → to make sure the GO TO command is highlighted at the bottom of the screen, then press ENT. The Cuda begins showing navigation
information to the item.
To cancel navigation, press MENU|MENU|↓ to CANCEL NAVIGATION|ENT|←
to YES|ENT. The Cuda stops showing navigation information.
Creating and Saving a Trail
A trail, or plot trail, is a string of position points plotted by the Cuda
350 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 flashing line extending from the back of the current position arrow.
The Cuda 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 2,000,
but the unit can record trails 9,999 points long). When the point limit is
reached, the Cuda begins recording the trail over itself.
By default, the trail flashes once a second, making it easier to see
against the background map. With the default setting, the Cuda cre107
ates a trail by placing a trail point on the screen every time you change
directions. (The methods used for creating a trail and the trail update
rate can 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 begins
recording a new trail.
To Save a Trail
1. Press MENU|MENU|↓ to MY TRAILS|ENT.
Visible Active

3. Press ↓ to ACTIVE|ENT. This unchecks the Active option.
4. To return to the previous page, press EXIT repeatedly. As you left the
Edit Trail menu, you will notice that a new trail was started with a
new sequential number. In the example figure below, the new trail is
number 15, showing zero points. Note that Trail 14 is inactive, but is
still visible on the map.
108
New trail, named Trail 3, is created when Trail 2 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.
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. Use → to select NEW TRAIL and press ENT.
Caution:
You also have the option of completely turning off trail recording, under the trail Options command. If, however, 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 with the default settings. You can selectively turn trail display on and off for any saved or
active trail. In the Saved Trails List, visible trails have a check mark in
front of the trail name.
109
To turn trail display on or off:
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 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.) Visual trailing, however, 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 flashing trail is visible.
2. Begin moving and watch the Map Page. Walk or steer so that your
current position arrow traces along the trail you have just made.
110
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 (forward)
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.
4. Press → to NAVIGATE ROUTE|ENT. The unit begins showing navigation
information along the trail.
NOTE:
If you are already located at or near the beginning of your trail, the
arrival alarm will go off as soon as you hit Enter. Just press EXIT to
clear the alarm.
5. Now, begin moving and let your Cuda 350 guide you.
6. When you reach your destination, be sure to cancel your navigation:
press MENU|MENU|↓ to CANCEL NAVIGATION|ENT. The unit asks if you're
sure. Press ←|ENT.

Icons
Icons are graphic symbols used to mark some location, personal point of
interest or event. They can be placed on the map screen, saved and recalled later for navigation purposes. These are sometimes referred to as
event marker icons. The Cuda 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 as waypoints do. You can not 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.
An icon can be created at the cursor position on the map or at your current position while you are navigating.

117
Routes
A route is a series of waypoints, linked together in an ordered sequence
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
waypoint. Once programmed into the GPS unit, a route gives users 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

Section 8: GPS Setup Options
Alarms
This unit has several GPS alarms. The default setting has all the
alarms 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 0.1 mile, then the alarm will flash a
message when you come within 0.1 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 0.1 mile, then the alarm flashes a message if you drift
0.1 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 0.1 mile as an example, if you are anchored and your
boat moves more than 0.1 mile, the alarm will flash a message and
sound a tone.

Auto Satellite Search
To lock onto the satellites, the GPS receiver needs to know its current
position, UTC time and date. (Elevation (altitude) is also used in the
equation, but it is rarely required to determine a position.) It needs this
data so that it can calculate which satellites should be in view. It then
searches only for those satellites.
When your GPS receiver is turned on for the first time, it does not know
what your position or elevation (altitude) is. It does know the current UTC
time and date since it has an internal clock that keeps time while the unit
is turned off. If the time and/or date are incorrect, you can set it using the
Set Local Time menu. The unit begins searching for the satellites using
the above data that it acquired the last time it was turned on. This
probably was at the factory. Since you almost certainly are not at our
factory, it is probably looking for the wrong satellites.
If it does not find the satellites it is looking for after one minute, the
unit will switch to Auto Search. The receiver looks for any satellite in
the sky. Due to advanced technology, the auto search time has shrunk
significantly from the early days of GPS.
Once the unit locks onto the satellites, it should take less than a minute to
find your position the next time it is turned on, provided you haven't
moved more than 100 miles from the last location it was used.

Menus for changing coordinate system used to display positions.
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, Greek and Military grids.
UTM's are marked on USGS topographic charts. This system divides
the Earth into 60 zones, each 6 degrees wide in longitude.
British, Irish, Finnish, German, New Zealand, Swedish, Swiss, Taiwan,
and Greek grid systems are each 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.
132
NOTE:
When the position format is changed, it affects the way all positions
are shown on all screens. This includes waypoints.

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
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 setup a map fix, follow these steps in order. Take your map of
the area and determine a reference latitude/longitude. (Please note
that 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.) 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 will have to deal
with. Once you have 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 from 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 following screen appears and MAP SCALE is highlighted. Press ENT

map in the location you selected with the cursor. The unit will consider
that spot its last known position until it actually locks on to a satellite
or until you initialize the GPS in another location.
Map Auto Zoom
This receiver has an auto zoom feature that eliminates much of the
button pushing common with other brands of GPS receivers. It works
in conjunction with the navigation feature.
First, start navigation to a waypoint. (See the waypoint section for
more information on navigating to a waypoint.) Then, with the auto
zoom mode on, the unit zooms out until the entire course shows, from
the present position to the destination waypoint. As you travel toward
the destination, the unit automatically begins zooming in — one zoom
range at a time — always keeping the destination on the screen.

Map Overlays (Range Rings; Lat/Long Grid)
The map screen can be customized with four range rings and/or grids
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, the 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 move around 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.
To set range rings: From the Map Data menu, press ↓ to RANGE RINGS.
With the range rings highlighted, press ENT to turn on (check) or turn
off (uncheck) the option.

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.
Map orientation is shown in north up (left) and in track up (right).
This is fine if you are always traveling north. What you see to your left
corresponds with the left side of the map and what is on your right is
shown on the right side of the map and so on. If, however, you travel
any other direction, the map does not line up with your view of the
world.
142
To correct this problem, track-up mode rotates the map as you turn.
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 track-up
or course-up mode is on, an "N" shows on the map screen to help you
see which direction is north.

Section 9: NMEA 0183 Connections
NMEA is a standard communications format for marine electronic
equipment. The Cuda 350 can send information to any device that receives NMEA 0183 data. This allows the unit to work with VHF marine
radios equipped with the Digital Selective Calling (DSC) distress call
feature.
To send NMEA 0183 data, the Cuda 350 has one NMEA 0183 version
2.0 communication port. The com port can be used to send NMEA formatted data such as your current position.
The provided Cuda 350 data cable plugs into the accessory socket on the
right side of the back of your unit's case. The data cable ends in two wires
that connect to your VHF radio or other NMEA device. The Cuda 350 uses
the yellow wire to transmit and the black shield wire for signal ground.
NOTE:
Some VHF radios, such as the popular Uniden® brand, have input levels which require use of an additional diode and resistor built into the
Cuda 350 data cable. This is Wiring Diagram A, which is described
on page 159. The majority of the DSC radios will work with the resistor and diode as provided by Eagle.
A few other radio brands (and other electronic devices) that meet the
NMEA 0183 standard won't need these adapters and you will have to
remove the resistor and diode to make those work. This is Wiring Diagram B, which is described on page 161.
Consult your other device's owner’s manual, then read through all of
the following instructions before you begin. Use the installation diagram most suited to your brand of radio or other device. If your device
manual indicates an RS-232 connection (i.e., a computer), remove the
resistor and diode and connect using Wiring Diagram B. Most other
connection types (TTL; NMEA + and NMEA –; differential) will require Wiring Diagram A.
156
Recommended Tools and supplies
Recommended tools for this job include: wire pliers or wire stripper and a
wire cutter. Required supplies for this job include: two gray (18 gauge) or
blue (16 gauge) wire nuts and electrical tape. Supplies are not included.
Wiring Diagram "A"
Begin by stripping the wire ends of the device you're connecting to the Cuda
350. (You'll notice the Cuda 350 data cable comes pre-stripped, with wire
ends exposed.) Use a pair of wire pliers to strip about 1/4-inch (6.35 mm) of
insulation from each of the radio's or other device's data wires.
Strip the ends of the VHF radio's data wires. Connect them to the prestripped wires of the Cuda 250 data cable (shown right).
Twist the exposed wires together as shown in the following figures. If
you're using a Uniden or similar radio, connect the radio's NMEA Wire
to the Cuda 350 data cable's yellow wire, and the radio's Ground/Shield
wire to the Cuda 350 data cable's black shield wire. If you're using another radio brand or NMEA device, see Wiring Diagram B instructions
on page 161.

Twist the appropriate wires together, making sure that the exposed
ends make good contact. Secure the wire ends with wire nuts, then
wrap each wire nut securely with electrical tape to protect against
moisture, as shown in the figure on the right.
After taping the wire ends individually, wrap the entire connection
with electrical tape as shown. This will help protect from moisture and
prevent the wires from breaking contact.
158
Wiring Diagram "B"
If your VHF radio or other device requires true RS-232, you will need to remove the diode and resistor built into the end of the Cuda 350 data cable.
You will notice near the end of the cable a segment protected with black
heat-shrink. To connect the Cuda 350 to a true RS-232 radio, first remove the Uniden adapter segment of the cable as shown in the following
figures.
For Wiring Diagram B installations, remove the Uniden adapter segment at the end of your data cable as shown at left. Snip off the end of
the cable protected by the black heat-shrink. At right, we have used
clear heat-shrink for clarity, so you can see the diode and resistor protected within. Remove this portion of the cable.
After you have removed the adapter segment, use wire pliers to expose
the ends of the five remaining wires in the cable. Cut off the black, blue
and white wires, then seal their ends with electrical tape.

wires from the radio or other device.
If you are using a true RS-232 radio or other device, connect its (+) Receive wire to the Cuda 350 data cable's yellow wire and its ground or (–
