Introduction
Thank you for buying an Eagle sonar! Your unit is a high-quality sonar designed for both professional and novice fishermen. All Eagle sonars have an automatic mode that finds and displays the bottom, fish,
underwater structure and more – right out of the box. All you have to
do is press the on (PWR) key.
However, if you want to fine-tune your unit, press the MENU UP key.
The TriFinder 2 has several powerful features you can control by
scrolling through easy-to-use menus with the arrow and menu keys.
To get started with your Eagle sonar, first read the installation section.
It contains instructions for mounting the sonar unit, the transducer
and any optional accessories, such as a speed sensor.
Following recommended installation practices will pay off in optimum
performance of your Eagle sonar. Improper installation can cause
problems down the road, especially if the transducer is badly mounted.
After you've read the installation instructions, install the unit and accessories. Then, read the rest of the manual. The more you know about
your sonar, the better it will work for you.
Take advantage of the Simulator feature. It allows you to practice operating your sonar before you get it in the water. And when you finally
head for your favorite fishing hole, take this manual along for reference.

NOTICE!
The storage temperature for your unit is from -4 degrees to +167
degrees Fahrenheit (-20 degrees to +75 degrees Celsius). Extended
storage 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.
Transducer Installation
These instructions will help you install your BroadView transducer on
a transom or trolling motor. Please read all instructions before proceeding with any installation.
2
Your BroadView transducer comes packaged with a trolling motor mount
that uses a plastic bracket with an adjustable strap. It also comes with a
bracket for mounting it to the transom of your boat. These are both
"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
Recommended tools include: two adjustable wrenches, flat-head screwdriver. If you prefer the option of routing the cable through the transom, you will need a 1" drill bit. The following installation types also
call for these recommended tools and required supplies (supplies are
not included):
Transom installation
Tools include: drill, #29 (0.136") drill bit. Supplies: high quality, marine
grade above- or below-waterline caulking compound.
Trolling motor installation
Tools: none. Supplies: plastic cable ties.
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.
3
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.
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 BroadView 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.
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.
4
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
A shoot-thru-hull installation is not recommended for the BroadView
transducer.
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.
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.

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.
Route cable over bolt and through bracket. Side view shown at left and
seen from above at 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 caulking 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.

Align transducer centerline with hull bottom and attach to transom.
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 1".
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 TMB-S bracket to the transducer as shown in the following figure, using the hardware supplied with the transducer. (Note:
The internal tooth washer is supplied with the TMB-S.)

2. Slide the adjustable strap supplied with the TMB-S through the slot
in the transducer bracket and wrap it around the trolling motor. Position the transducer to aim straight down when the motor is in the
water. Tighten the strap securely.
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.
Speed/Temperature Sensors
The TriFinder 2 can accept an optional speed sensor for showing speed
and distance traveled. It can also accept an optional temperature sensor, or a combination speed/temp sensor.

Speed Sensor Installation
If you wish to purchase an optional sensor for your unit, refer to the
accessory ordering information inside the back cover of this manual.
The following instructions describe how to install the speed sensor.
Recommended tools for this job include: drill, 7/8" drill bit, 1/8" drill bit for
pilot holes, screwdriver. Required supplies for this job include: four #8
stainless steel wood screws (3/4" long), high quality, marine grade aboveor below-waterline caulking compound.
First find a location on the boat's transom where the water flow is smoothest. Don't mount the sensor behind strakes or ribs. These will disturb the
water flow to the speed sensor. Make sure the sensor will remain in the
water when the boat is on plane. Also make sure the location doesn't interfere with the boat's trailer. Typically, the sensor is mounted about one foot
to the side of the transom's centerline.
Once you've determined the proper location for the unit, place the sensor on the transom. The bottom of the bracket should be flush with the
hull's bottom. Using the sensor as a template, mark the hull for the
screws' pilot holes. Drill four 1/8" holes, one in each end of the slots.
Mount the sensor to the hull using #8 stainless steel wood screws (not
included). Use a high quality, marine grade above- or below-waterline
caulking compound to seal the screws. Make sure the sensor is flush
with the bottom of the hull and tighten the screws.
12
If the base of the transom has a radius, fill the gap between the transom and the sensor with the caulking compound. This will help ensure
a smooth water flow.

Route the sensor's cable through or over the transom to the sonar unit.
If you need to drill a hole in the transom to pass the connector through,
the required hole size is 7/8".
Caution:
If you drill a hole in the transom for the cable, make sure it is located above the waterline. After installation, be sure to seal the
hole with the same marine grade above- or below-waterline sealant used for the screws.
The sensor is now ready for use. Connect the sensor to the in-line connector on the power/sensor cable. If you have any questions concerning
the installation of the sensor, please contact your local boat dealer.
POWER CONNECTIONS
The unit works from a twelve-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.

Power connections for TriFinder 2.
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.
CAUTION:
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 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, Bracket or Portable
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-4
mounting kit.
In-Dash Installation
The following figure shows dimensions for in-dash mounting. The FM-4
in-dash mounting kit includes a template for cutting the mounting hole

If you use the supplied gimbal bracket, you may be interested in the
optional GBSA-1 swivel bracket kit. This converts the unit's gimbal
bracket to a swivel mount which can be used on the dash or overhead
mounting positions. Installation instructions for the in-dash and swivel
mounting kits are supplied with the adapter kits.
Bracket Installation
Mount the unit in any convenient location, provided there is clearance
when it’s tilted for the best viewing angle. Holes in the bracket’s base
allow wood screw or through-bolt mounting. It may be necessary to
place a piece of plywood on the back side of thin panels to reinforce the
panel. Make certain there is enough room behind the unit to attach the
power and transducer cables.

Drill a 1-inch (25.4 mm) hole in the dash for the power and transducer
cables. The best location for this hole is immediately under the gimbal
bracket location. This way, the bracket can be installed so that it covers
the hole, holds the cables in position and results in a neat installation.
Some customers, 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 transducer connector up through the
hole from under the dash. Drop the power cable's bare-wire end down
though the hole from the top.
If you wish, you can fill in the hole around the cables with a good marine caulking 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 cables to allow tilting or swiveling
the unit. If you choose to fill in the hole, be sure to position the cables
against the rear edge of the hole as you apply the fill material.
Before positioning the bracket, be sure to hold the cables against the rear
edge of the hole. Then, slide the bracket over the hole and butt the rear
16
of the bracket base firmly against the cables, thus pinning them in place
against the side of the hole. Finally, fasten the bracket to the dash.
Attach the unit to the gimbal bracket using the supplied gimbal knobs
and washers. 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 Sonar Installation
Like many Eagle products, the TriFinder 2 sonar is capable of portable
operation by using the optional PPP-10 portable power pack. The power
pack and portable or floating transducers expand the uses for your sonar. You can use your TriFinder 2 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.
The PPP-10 package includes the power pack, battery adapter and a
portable transducer. Batteries are not included. The power pack has a
storage compartment for the portable transducer. The pack can be used
with eight "D" cell alkaline batteries or an optional sealed, rechargeable
battery. For set-up directions, refer to the pack's instruction sheet, part
988-1047-45.
"D" cell battery
Install batteries in power case battery adapter.
17
NOTE:
Though the PPP-10 will give you the liberty of a portable sonar
unit, the portable transducer that comes with it is not a BroadView transducer. While using the portable transducer you will
not get the extra sonar information necessary to use TargetTrack.

Depth scales on the right side of the screen makes it easy to determine
the depth of fish, structure, and other targets. The line at the top of the
screen represents the surface. The bottom depth (as determined by the
digital sonar) shows in the upper left corner. If an optional speed or
temperature sensor is connected, digital displays for speed and/or temperature will also be shown.

RANGE
When turned on for the first time, the unit automatically adjusts the
depth range according to water conditions. It always keeps the bottom
displayed in the lower portion of the screen. You can over-ride the
automatic range control and manually select a range.
To do this, press MENU until the RANGE menu appears. Use the arrow
keys to select the desired range. When you're finished, press PWR to
clear the menu from the display
Range Select menu.
This unit has the following ranges:
10, 15, 20, 30, 40, 60, 80, 100, 150, 200, 300, 500, 800 and 1,000 feet.
23
ZOOM
The zoom feature enlarges all echoes on the screen. The 2X zoom doubles
the size of the echoes on the display; the 4x zoom quadruples the echo size.
To zoom the display, first press the MENU key until the ZOOM menu appears. Use the arrow keys to select either 2X or 4X zoom, then press
PWR to clear the menu.
Zoom screen, showing Zoom menu and the 2X zoom
indicator at the top right of the screen.
When the display is in Zoom mode, the screen will show a zoom indicator box at the top right corner of the screen. This is a reminder that the
display is zoomed, and it tells what level of zoom is in effect.
To turn the zoom feature off, press the MENU key until the ZOOM menu appears. Use the arrow keys to select OFF, then press PWR to clear the menu.
NOTE:
Using the Zoom command while in auto Range mode will always
enlarge the echoes near the bottom, because auto Range always
keeps the bottom displayed in the lower portion of the screen.
When you Zoom in manual Range mode, echoes are enlarged near
the middle of the displayed range. For example, with a manual
depth Range of 100 feet, your screen shows the water column from
zero at the top of the screen to 50 feet in the middle to 100 feet at
the bottom of the screen. Select 2X Zoom and the screen will show
the water column from zero to 50 feet, with 25 feet shown in the
middle of the screen. Select 4X Zoom and the screen shows the wa24
ter column from 13 feet to about 39 feet, with 25 feet still in the
middle of the screen.
Important Tip:
Your unit has the handy 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 as it scrolls, 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
23) and turn on 2x or 4x Zoom. Then, simply press the UP ARROW
or DOWN ARROW to pan up and down the water column.

Fig. 3
In 34 feet of water, with the Range set manually at 60 feet, the unit
shows the entire water column in Fig. 1. To get a closer look, turn
around and follow your wake to troll over the structure again. With
the unit in 4x zoom, press the down arrow key to look at the six fish
along the ledge, then press the up arrow to pan up the water column to
see four game fish threatening a school of forage fish.
SENSITIVITY
Sensitivity controls the unit's ability to pick up echoes. If you want to
see more detail, try increasing the sensitivity, a little at a time. There
are situations when too much clutter appears on the screen. Decreasing
the sensitivity can reduce the clutter and show the strongest fish echoes, if fish are present. As you change the sensitivity setting, you can
see the difference on the chart as it scrolls.

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 Sensitivity mode or Manual Sensitivity mode. The adjustment method works
the same in both modes, but it gives you slightly different results.
Adjusting sensitivity in Auto Sensitivity Mode is similar to manually adjusting a car's speed with the accelerator pedal while cruise control is on.
You can tell the car to run faster, but when you let off the gas the cruise
control automatically keeps you from running slower than the minimum
speed setting. In your unit, auto mode will let you increase sensitivity to
26
100 percent, but the unit will limit your minimum setting. This prevents
you from turning sensitivity down too low to allow automatic bottom
tracking. When you change the setting with auto turned on, the unit will
continue to track the bottom and make minor adjustments to the sensitivity level, with a bias toward the setting you selected.
Adjusting sensitivity in Manual Sensitivity Mode is similar to driving a
car without cruise control — you have complete manual control of the
car's speed. In your unit, manual mode allows you to set sensitivity at
100 percent (maximum) or zero percent (minimum.) Depending on water and bottom conditions, the bottom signal may completely disappear
from the screen when you reduce sensitivity to about 20 percent or less!
Try adjusting sensitivity in both auto and manual modes to see how
they work.
Sensitivity menu screens. Left, automatic or manual menu.

To adjust sensitivity:
Press MENU until the SENSITIVITY ADJUSTMENT menu appears. Press UP
ARROW to increase the sensitivity, DOWN ARROW to decrease it. When
it's set at the desired level, press PWR to clear the menu.
The sensitivity percentage in use shows in this menu. As you change
the setting, echoes scrolling onto the screen will show the effects of the
change. If you reach the maximum or minimum sensitivity level, a tone
sounds alerting you to the limits.
27
NOTE:
If you want to change the sensitivity in Manual Mode, first turn off
Auto Sensitivity: press MENU until the SENSITIVITY AUTOMATIC/MANUAL
menu appears. Press DOWN ARROW to select MANUAL, then press PWR to
clear the menu. To adjust the sensitivity, follow the same steps used for
adjusting sensitivity in auto mode above.
®
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 or no gray line. 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. The factory default for this unit is 69 percent.
Since Grayline shows the difference between strong and weak signals,
adjusting the sensitivity may also require a different Grayline level.
The level chosen by the sonar unit at power on is usually adequate for
most conditions. Experiment with your unit to find the Grayline setting
that's best for you.
To change Grayline level, press MENU until the GRAYLINE menu appears.

FISH I.D.
The Fish I.D. feature identifies targets that meet certain conditions
as fish. The microcomputer analyzes all echoes and eliminates surface
clutter, thermoclines and other signals that are undesirable. In most
instances, remaining targets are fish.
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.

Fish arches
At left, underwater scene in normal fish arch mode. Right, Fish I.D.
menu with the feature turned on.
Fish I.D. is an easier way for a sonar novice to recognize a fishy signal
return when he sees it. However, locating fish by symbol only has some
limitations.
Your sonar unit's microcomputer is sophisticated, but it can be fooled.
It can't distinguish between fish and other suspended objects such as
trotlines, turtles, submerged floats, air bubbles, etc. Individual tree
limbs extending outward from a group of limbs are the hardest objects
for the Fish I.D. feature to distinguish from fish.
To see what's under your boat in maximum detail, we recommend you
turn off Fish I.D. and begin learning to interpret fish arches.
29
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 simply interpreting sonar returns in a specific way to help take some of the work
out of reading the screen. Remember: Fish I.D. is one of the many tools
we provide so you can analyze your sonar returns for maximum fish
finding information. This and other features can help you successfully
"see" beneath the boat under varied water and fishing conditions. So,
practice with the unit in both the Fish I.D. mode and without to become
more familiar with the feature. The default for Fish I.D. is off.
Fish I.D. is most handy when you're in another part of the boat or performing some task that prevents you from watching the sonar screen.
Then, you can turn on Fish I.D. and the audible fish alarm. When that
lunker swims under your boat, you'll hear it!
Fish I.D. can also be useful when you want to screen out some of the sonar detail gathered by your unit. For example, it can help cut through
the clutter of suspended bubbles caused by wave action or boat wakes.
To turn Fish I.D. on, press MENU until the FISH ID menu appears. Press
UP ARROW to select ON, then press PWR. To turn it back off, repeat the
above steps, but press DOWN ARROW to select OFF.
FISHTRACK™
The FishTrack feature shows the depth of a fish symbol when it appears on the display. To turn it on, press MENU until the FISH ID menu
appears. Press UP ARROW to select TRACK ON, then press PWR. To turn it
off, repeat the above steps, but press DOWN ARROW to select OFF. (If you
want to turn off FishTrack depths but leave Fish I.D. on, press DOWN
ARROW to select ON, then press PWR.) Remember, Fish I.D. must be on
in order to use the FishTrack feature.

TARGETTRACK
The TriFinder 2 has the unique ability to "see" targets not only straight
down, but also to the right and left, thanks to the BroadView™ transducer. The TargetTrack feature shows you if the target is to the left,
right or straight down.
The BroadView transducer has three elements: left, right and down.
The TriFinder uses all three elements to display targets between the
surface and the bottom.
Targets are shown as Fish I.D. symbols. This feature also shows the depth
of the target directly above the fish symbol. In the following figure, there
are two symbols from the right element at 4 feet and 5 feet; one from the
left element at 35 feet, and one from the center element at 15 feet.
Target Track Screen.
The TargetTrack feature identifies fish symbols coming from the right
element with a "R" in front of the symbol's depth. An "L" identifies
symbols from the left element. No letter identifies fish symbols from the
center element. The bottom signal and the digital depth display are
read from the center element only.
To turn TargetTrack on, press MENU until the FISH ID menu appears.
Press UP ARROW to select TRACK L&R, then press PWR to clear the menu.
To turn TargetTrack off, press MENU until the FISH ID menu appears.

FISHREVEAL
When displaying actual sonar returns, the FishReveal feature helps
show fish targets hidden by surface clutter, thermoclines, weed beds
and other cover with 10 levels of gray tones.
Normal operation (with FishReveal turned off) shows the weakest echoes as black and the strongest in light gray. Since all weak echoes are
black, fish arches show boldly against the white background. The
drawback is that all weak echoes — such as thermoclines — are also
accentuated. This can make it hard to distinguish fish signals inside
thermoclines or other cover.
At left FishReveal menu screen. The feature is off and screen is in
normal mode. Right, Fish Reveal is on, in standard mode.
There are two FishReveal modes: standard and inverted. In standard
mode, the weakest echoes are white and the strongest echoes are black.
Echoes in between vary in gray in proportion to their signal strength.
32
In Inverted FishReveal mode, the weakest echoes are black and the
strongest echoes are white. Again, echoes in between vary in gray in
proportion to their signal strength. In all modes, the Grayline control
determines the range for black to white.
At left, standard FishReveal mode. Right, Inverted Fish Reveal mode.
To turn FishReveal on, press MENU DOWN until CHART SETUP appears,
then press UP ARROW. Press MENU DOWN until CHART MODE appears.
Press DOWN ARROW to select the desired FishReveal mode. Press PWR

steps, but select NORMAL before clearing the menu.
CHART SCROLL SPEED and HYPERSCROLL
The rate that echoes scroll across the screen is called the chart scroll
speed. The default for this unit is 60 percent; we recommend that you
leave the scroll speed set there for virtually all fishing conditions.
However, you might consider experimenting with chart speed when you
are stationary or drifting very slowly. You may sometimes achieve better images as you slow down the chart speed to match how fast you are
moving across the bottom.
Switching to a scroll speed faster than 60 percent can be helpful when
running at high speed. Any setting greater than 60 switches the unit to
HyperScroll. This feature scrolls the echoes at an extremely high rate
of speed, giving you the maximum screen update.
If you are at anchor, ice fishing or fishing from a dock, experiment with
a chart speed of 20 percent. If you are drifting slowly, try a chart speed
of 40 percent. When you are stationary and a fish swims through the
33
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.
At right, Scroll Speed menu at default 60 percent setting. At left, Scroll
Speed menu, with unit set to HyperScroll mode.
If you are running fast, try a HyperScroll setting of 80 to 100 percent.
When using HyperScroll, you may also need to manually decrease the
sensitivity for best performance. Depending on water conditions, HyperScroll may cause a second bottom echo and large amounts of clutter
to appear 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.
Adjust scroll speed by pressing MENU until SCROLL SPEED appears. Press
UP ARROW to increase it and press DOWN ARROW to decrease it. Press
PWR to clear the menu.
To return to the original setting, repeat the above steps, but use the
arrow keys to set the speed at 60 percent before clearing the menu.
NOISE REJECT and ASP (Advanced Signal Processing)
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 and wiring, air bubbles passing
34
over the face of the transducer, even vibration from the engine. In all
cases, noise can produce unwanted marks on the display.
The ASP noise rejection feature is especially useful because it typically
lets you operate the boat at all speeds without adjusting the sensitivity
or other controls.
Noise Reject menu.
The ASP feature has four settings — Off, Low, Medium and High.
When first turned on, noise rejection is set on low. If you have high
noise levels, try using the medium or high ASP setting. However, if you
are having trouble with noise, we suggest that you take steps to find
the interference source and fix it, rather than continually using the
unit with the high ASP setting.
There are times when you may want to turn ASP off. This allows you to
view all incoming echoes before they are processed by the ASP feature.
To change the ASP setting, press MENU DOWN until NOISE REJECT appears. Use the up and down arrow keys to select the desired setting,
then press PWR to clear the menu.
ALARMS
The sonar unit has two different types of alarms, fish and depth.
Fish Alarm
The Fish Alarm sounds a tone when a fish symbol appears on the
screen. The default setting is on, but the Fish I.D. feature must be
turned on for fish alarms to work.

Depth Alarms
The depth alarms are triggered only by the bottom signal. No other
echoes will activate these alarms. The depth alarms consist of a shallow
and a deep alarm. The shallow alarm sounds an alarm tone when the
bottom goes shallower than the alarm's setting. The deep alarm sounds
a tone when the bottom goes deeper than its setting. Both alarms adjust the same way, although through different menus.

NOTE:
If you turn on your unit before attaching a transducer, it may enter a
demo mode. The words "demo mode" flash on the bottom of the
screen and a sonar chart plays much like the Simulator feature. 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.
CHART SETUP
The Chart Setup menu lets you further customize the display. The size
of the digital numbers for the depth, temperature, speed and distance
log can be customized from this menu. The depth scales shown on the
right side of the screen can be modified, and the Fish Reveal modes can

menu keys to cycle through the chart setup menus.
Chart Setup menu.
LIMIT SEARCH
The Limit Search command helps you maintain maximum chart detail
when you are moving fast in deep water (about 200 feet.) When turned
on, Limit Search prevents the digital sonar from over-riding the sonar
chart's depth range setting.
Limit Search does this by preventing the digital sonar from slowing
down the ping speed as it automatically searches for and tracks the bottom. The default setting is off, and this should fit most freshwater
fishing situations.
High boat speed and slow ping speed (caused by the deeper bottom) can
reduce the screen refresh rate. This in turn can reduce the amount of
43
detail seen on the sonar chart. Try this command only if you are in deep
water, traveling at high speed, and notice a reduction in detail on the
sonar chart. When Limit Search is turned on, the digital sonar will
limit its search for the bottom to the depth range you have set for the
sonar chart.
NOTE:
Turning Limit Search on can cause the digital sonar to lose the bottom in some situations. The digital depth will flash if that occurs.
The sonar chart must be in manual depth range mode to use the Limit
Search command. To switch from auto depth range to manual, press
MENU until the RANGE menu appears. Use the arrow keys to select the
desired range. When you're finished, press PWR to clear the menu from
the display.

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:
1. The transducer has not yet been connected or has been disconnected.
To leave demo mode, make sure the transducer 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
are securely plugged in to the unit.
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
46
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. 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. 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.
