NOTICE!
The storage and operation temperature range for your unit is from
-4 degrees to +167 degrees Fahrenheit (-20 degrees to +75 degrees
Celsius). Extended storage or operation in temperatures higher or
lower than specified will damage the liquid crystal display in your
unit. This type of damage is not covered by the warranty. For more
information, contact the factory's Customer Service Department;
phone numbers are inside the manual's back cover.
How Sonar Works
Sonar has been around since the 1940s, so if you already know how it
works, skip ahead to the next segment. But, if you have never owned a
sonar fish finder, this segment will explain the under water basics.
Sonar is an abbreviation for SOund NAvigation and Ranging, a technology developed during World War II for tracking enemy submarines.
A sonar consists of a transmitter, transducer, receiver and display. In
simple terms, here's how it finds the bottom and 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 not 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 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.
3
Dual Search & Dual Frequency
The FishEasy 250 DS is packed with a Dual Search Skimmer Transducer that can transmit at 83 kHz and 200 kHz. The SeaFinder 250 DF
has a dual frequency transducer that transmits at 50kHz and 200kHz.
A new innovation, the 83 kHz frequency offers superior sonar performance at all depths from very shallow up to 1,000 ft and provides up to
120º of fishfinding coverage.
Preparations
You can install the sonar system in some other order if you prefer, but
we recommend this installation sequence:
Caution:
You should read over this entire installation section before drilling any holes in your vessel!
1. Determine the approximate location for the sonar unit, so you can
plan how and where to route the cables for the transducer and power.
4
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
unit.
5. Install the power cable and route it to the sonar unit.
6. Mount the sonar unit.

Section 2:
Installation & Accessories
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.
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 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. The following installation types also call for
these recommended tools and required supplies (supplies 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 compound.
Trolling motor installations
Tools: two adjustable wrenches, flat-head screwdriver. Supplies: plastic
cable ties.
7
Shoot-through hull installations
Tools: these will vary depending on your hull's composition. Consult
your boat dealer or manufacturer. Supplies: 100 grit sandpaper, good
quality epoxy adhesive.
Selecting a Transducer Location
1. The transducer must be placed in a location that has a smooth flow
of water at all times. If the transducer is to be mounted inside the
hull, then the chosen location must be in the water at all times. If the
transducer is not placed in a smooth flow of water, interference
caused by bubbles and turbulence will show on the sonar's display in
the form of random lines or dots whenever the boat is moving.
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 location on aluminum boats is between the ribs closest to the engine.
2. The transducer should be installed with its face pointing straight
down, if possible.
3. If the transducer is mounted on the transom, make sure it doesn't
interfere with the trailer or hauling of the boat. Also, don't mount it
closer than approximately one foot from the engine's lower unit. This
will prevent cavitation (bubble) interference with propeller operation.
4. 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.
8
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.
Transom
Transducer
centerline
Hull bottom
Align transducer centerline with hull bottom.
If you want to adjust the transducer slightly higher or lower, the slots
in the mounting brackets allow you to loosen the screws and slide the
9
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 want, 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.
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.
The shoot-thru-hull installation does have its drawbacks, though. 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. Lack of angle adjustment can be particularly troublesome on hulls that sit with the bow high when at rest
or at slow trolling speeds.
10
Third, a transducer CAN NOT shoot through wood and metal hulls.
Those hulls require either a transom mount or a thru-hull installation.
Fourth, if your Skimmer transducer has a built in temp sensor, it will
only show the temperature of the bilge, not the water surface temp.
Follow the testing procedures listed in the shoot-thru-hull installation
section at the end of this instruction booklet to determine if you can
satisfactorily shoot through the hull.
Transom Transducer Assembly and Mounting
The best way to install 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.
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.
11
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.
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!
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.
13
Route cable over bolt and through bracket. Side view (left) and shown
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 compound.
Adjust the transducer so that it's parallel to the ground and tighten
the nut until it touches the outer washer, then add 1/4 turn. Don't
over tighten the lock nut! If you do, the transducer won't "kick-up" if
it strikes an object in the water.

6. Route the transducer cable through or over the transom to
the sonar unit. Make sure to leave some slack in the cable at the
transducer. If possible, route the transducer cable away from other
wiring on the boat.
14
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
sealant used for the mounting screws.
7. Make a test run to determine the results. If the bottom is lost at
high speed, or if noise appears on the display, try sliding the transducer bracket down. This puts the transducer deeper into the water,
hopefully below the turbulence causing the noise. Don't allow the
transducer bracket to go below the bottom of the hull.
Trolling Motor Bracket Installation
1. Attach the optional TMB-S bracket to the transducer as shown in the
following figure, using the hardware supplied with the transducer.
The internal tooth washer is supplied with the TMB-S.

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

Transducer Orientation and Fish Arches
If you do not get good fish arches on your display, it could be because
the transducer is not parallel with the ground when the boat is at rest
in the water or at slow trolling speeds.

If the arch slopes up – but not back down – then the front of the transducer is too high and needs to be lowered. If only the back half of the
arch is printed, then the nose of the transducer is angled too far down
and needs to be raised.
NOTE:
Periodically wash the transducer's face with soap and water to remove any oil film. Oil and dirt on the face will reduce the sensitivity or may even prevent operation.
17
Shoot-Thru-Hull Preparation
Hulls With Flotation Materials
The transducer installation inside a fiberglass hull must be in an area
that does not have air bubbles in the resin or separated fiberglass layers. The sonar signal must pass through solid fiberglass. A successful
transducer installation can be made on hulls with flotation materials
(such as plywood, balsa wood or foam) between layers of fiberglass if
the material is removed from the chosen area. See the figure below.
WARNING:
Do not remove any material from your inner hull unless
you know the hull's composition. Careless grinding or
cutting on your hull can result in damage that could
sink your boat. Contact your boat dealer or manufacturer to confirm your hull specifications.
Fill with

Inner hull
Flotation material
Epoxy to hull first
Outer hull
Epoxy the transducer to a solid portion of the hull.
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, the hull is watertight
and structurally sound. Remember, the sonar signal must pass through
solid fiberglass. Any air bubbles in the fiberglass or the epoxy will reduce or eliminate the sonar signals.
18
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 will 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. Do not touch the controls once they have been set.
True bottom
Second bottom
Manual range setting
Example of a second bottom signal. Unit is in 30 feet of water, with
range set at 80 feet and sensitivity set to 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. Notice how the signal strength decreases. The second bottom signal will probably disappear and the bottom signal intensity will likely decrease.
19
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 not get an acceptable bottom signal, try turning up the sensitivity by three or five keystrokes and then move the transducer around
once more. If you find a spot that works, mark it and move on to step 4.
If you have to turn up sensitivity by more than five keystrokes to get a
good signal, the transducer should be mounted on the outside of the
hull. This is especially true if you have to turn sensitivity all the way
up to get a decent bottom signal.
4. Most people can get good results by following steps 1 through 3, so
this step is optional. If you want to make an extra effort to be absolutely sure that your selected location will work under all conditions,
make a test run with the boat on plane and observe the bottom signal.
You will 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 are satisfied with a location, mark it and proceed with the
installation.

Shoot-thru-hull Installation
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.
21
Thoroughly stir the two compounds together until the mixture has a
uniform color and consistency. Do not mix too fast or bubbles will form
in the epoxy. After mixing, you have 20 minutes to complete the installation before the epoxy becomes unworkable.
Spread a thin layer of epoxy (about 1/16" or 1.5 mm thick) on the face of
the transducer as shown in the previous figure. Make sure there are no
air pockets in the epoxy layer! Then, apply the remaining epoxy to the
sanded area on the hull.
3. Press the transducer into the epoxy, twisting and turning it to force
any air bubbles out from under the transducer face. Stop pressing when
you bottom out on the hull. When you are 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.
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.
22
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.

WARNING:
Do not use this product without a 3-amp fuse wired into
the power cable! Failure to use a 3-amp fuse will void
your warranty. 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.
23
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.
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. 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 dashmounting kit. The FM-5 mount kit will work for both the FishEasy 250
DS and SeaFinder 250 DF.
In-Dash Installation
The following figure shows dimensions for in-dash mounting. The indash adapter kit includes a template for cutting the mounting hole and
complete installation directions on instruction sheet 988-0147-43.
NOTE:
Your unit needs only one cable, but some of the other products covered by the FM-5 instruction sheet use more. When installing your
unit, use the instructions for the transducer cable and ignore references to any others.

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

unit mounted on gimbal bracket.
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 gimbal 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 want, 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. No matter what type of installation you prefer, be
sure to leave enough slack in the cable to allow tilting or swiveling the unit.
26
If you choose to fill in the cable hole, be sure to position the cable
against the rear edge of the hole as you apply the fill material.
Before positioning the gimbal bracket, be sure to hold the cable against
the rear edge of the hole. Then, slide the bracket over the hole and butt
the rear of the bracket base firmly against the cable, thus pinning it in
place against the side of the hole. Finally, fasten the bracket to the
dash.
Front
Install the gimbal bracket. Orient the bracket so the arms slope toward the front of your unit.
Attach the unit to the gimbal bracket using the supplied gimbal knobs
and washers. Slide the rubber washers onto the gimbal knobs then
loosely screw the knobs into their sockets. Slide the unit into the
bracket with the rubber washers to the outside of the bracket arms.
Tilt the unit to the desired viewing angle and tighten the knobs finger
tight.
Portable Installation
Like many Eagle products, this sonar unit is capable of portable operation by using an optional portable power pack. The power pack and an
optional portable transducer expand the uses of your sonar unit. The
power pack makes it easy to use the unit on your boat or take it to the
dock, on a float tube, on an ice fishing trip or as a second sonar in a
friend's boat. The portable power pack can be used with eight "D" cell
27
alkaline batteries or an optional sealed, rechargeable battery. For setup directions, refer to the pack's instruction sheet.
"D" cell battery
Install batteries in power case battery adapter.
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.
28
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.

Clean the chosen area of the hull before attaching the suction cup. Locate the transducer on the hull as shown in the following figure. Don't
allow the bracket to extend below the hull, because water pressure
against it can cause the suction cup to come off at speed.
29
Moisten the cup, then press it onto the hull as firmly as possible. Tie
the nylon cord to the boat and route the transducer cable to the sonar
unit. Your portable sonar is now ready for use.
NOTE:
For optimum operation, the portable transducer should be adjusted
so that it is parallel to the ground. For more information on this,

FasTrack gives you a rapid update of conditions directly under the
boat, making it useful for ice fishing or when fishing at anchor. When
the boat is not moving, fish signals are long, drawn out lines on a normal display. FasTrack converts the graph to a vertical bar graph that
makes a useful addition to fishing at a stationary location.
Depth Range
The unit automatically adjusts the depth range according to water conditions. When in auto range mode, it always keeps the bottom displayed in the lower portion of the screen. You can override automatic
depth range control and manually select a depth range.
To do this, repeatedly press MENU until the DEPTH RANGE menu appears.
Press ↓ to select MANUAL, then press MENU UP to display the RANGE menu.

Sensitivity
Sensitivity adjusts the way echoes are displayed on the screen. If you
want to see more detail, try increasing the sensitivity, a little at a time.
When there is too much clutter on the screen, decrease sensitivity to
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.
38
Sensitivity set to manual mode (left). Sensitivity scroll bar (right).
You can change the sensitivity level whether you are in Auto Sensitivity

Grayline®
Grayline lets you distinguish between strong and weak echoes. It 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 line or no gray line at all. A hard surface returns
a strong signal, which will be displayed as a wide gray line.
40
Grayline scroll bar.
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 and fish from structure.
Wider
Grayline
Thin or no Grayline
A small amount of Grayline indicates a soft bottom (left), probably
sand or mud. More Grayline indicates a harder, rocky bottom (right).
Grayline is adjustable. Since Grayline shows the difference between
strong and weak signals, adjusting the sensitivity may also require a
different Grayline level.
41
The default level of Grayline is usually adequate for most conditions.
Experiment with the unit to find the Grayline setting best for you.
To change the Grayline level, repeatedly press MENU until the GRAYLINE
scroll bar appears. Press ↑ to increase Grayline, ↓ to decrease it. The effects of the Grayline adjustment will be shown by echoes on the screen.
If you reach the maximum or minimum level, a tone will sound. Press
PWR to clear the menu.
Chart Speed
The speed at which echoes scroll across the screen is called the chart
speed. The default for this unit is "max" (100 percent). We recommend
you leave the scroll speed setting there for most fishing conditions.
Chart Speed scroll bar.
You, however, might consider experimenting with chart speed when
you are stationary or drifting very slowly. Sometimes, you may achieve
better images as you decrease the chart speed to match the speed of
your boat.
If you are at anchor, ice fishing or fishing from a dock, experiment with
a chart speed of 25 percent. If you are drifting slowly, try a chart speed
of 50 percent. When you are stationary and a fish swims through the
42
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.
To adjust Chart Speed, repeatedly press MENU until the CHART SPEED
scroll bar appears. Press ↑ to increase the speed of the chart. Press ↓ to
decrease it. Press PWR to clear the menu.
To return to the original setting, repeat the steps above, but use ↑ to
set the speed to 100% before clearing the menu.
Frequency
The FishEasy 250 DS has a Dual Search transducer that can transmit
signals at 83 kHz and 200 kHz. The SeaFinder 250 DF is packed with a
Dual Frequency transducer that transmits at 50 kHz and 200 kHz.
The 200 kHz signal is best used in shallow water (about 300 feet or
less). This frequency is the best choice for about 80 percent of the fresh
and salt water sport fishing applications. When you get into very deep
salt water, up to 1,000 feet, the 83 kHz or 50kHz frequencies will work
best.
The 200 kHz transducer offers better detail and definition, but less depth
penetration. With the 83 kHz or 50 kHz frequencies, you will not get as
much detail or definition, but will benefit from greater depth penetration.
The 83 kHz also has up to 120° of wide fish-finding coverage. Remember,
all sonar units typically read deeper in fresh water than in salt water.

Fish I.D.
The Fish I.D. feature displays — as fish — targets that meet certain
conditions. The microcomputer analyzes all echoes and eliminates surface clutter, thermoclines and other undesirable signals.
The Fish I.D. feature displays symbols on the screen in place of the actual fish echoes. There are three symbol sizes: small, medium and
large. These show the relative size between targets. In other words, it
displays a small fish symbol when it thinks a target is a small fish, a
medium fish symbol on a larger target and so forth.
Fish I.D., the default setting for your unit, is an easier way for a sonar
novice to recognize a fish signal return when he sees it. But, locating
fish by symbol only does have some limitations.
44
Your sonar unit's microcomputer is sophisticated, but it 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 outward from a group of limbs are the
hardest objects for the Fish I.D. feature to distinguish from fish.

To see what is under your boat in maximum detail, we recommend you
turn off Fish I.D. and begin learning to interpret fish arches.
You may see Fish I.D. symbols on the screen when actually, there are no fish.
The reverse is also true — Fish I.D. can actually miss fish that are present.
Does that mean Fish I.D. is broken? No — the feature is interpreting sonar returns in a specific way to help take some of the work out of reading
the screen. Remember: Fish I.D. is one of the many tools we provide so
you can analyze your sonar returns for maximum fish finding information. This and other features can help you "see" beneath the boat under
varied water and fishing conditions. Practice with the unit with the Fish
I.D. mode on and off to become more skilled at interpreting sonar returns.
Fish I.D. is most handy when you are in another part of the boat or performing some task that prevents you from watching the sonar screen.
45
Then, you can turn on Fish I.D. and the audible fish alarm. When that
lunker 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 gathered by your unit. For example, it can help cut through
the clutter of suspended bubbles caused by wave action or boat wakes.
To turn Fish I.D. on or off, repeatedly press MENU until the FISH ID
menu appears. Press ↓ to select ON or OFF, then press PWR to clear the
menu from the screen.

Noise Rejection and ASP
The ASP (Advanced Signal Processing) feature is a noise rejection
system built into the sonar unit. It constantly evaluates the effects of
boat speed, water conditions and electrical interference and automatically gives you the best display possible under most conditions.
ASP is an effective tool in combating noise. In sonar terms, noise is any
undesired signal. It is caused by electrical and mechanical sources such
as bilge pumps, engine ignition systems, wiring, air bubbles passing
50
over the face of the transducer and even vibration from the engine. In
all cases, noise can produce unwanted marks on the display.
Noise Rejection menu.
The ASP noise rejection feature is especially useful because, typically,
it lets you operate the boat at all speeds without adjusting the sensitivity or other controls.
The ASP feature has three settings — Off, Low and High. When first
turned on, noise rejection is set on low. 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 the high ASP
setting. There are times when you may want to turn off ASP. This allows you to view all incoming echoes before they are processed by the
ASP feature.
To change the ASP setting, repeatedly press MENU until the NOISE
REJECTION menu appears. Use ↑ ↓ to select the desired setting, then press
PWR to clear the menu.

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 turns on only in simulator mode:
There is a problem with the transducer or the transducer cable. Check
the cable for damage.
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
are securely plugged in to the unit.
59
Weak bottom echo, digital readings erratic, or no fish signals:
1. Make certain 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. Do NOT use RTV silicone
rubber adhesive or Marine-Tex 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 signals such as fish or even structure from the display.
60
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 certain 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 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)].
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.
61
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 certain 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 certain 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.
