INTRODUCTION

Thank you for purchasing an Eagle sonar. Your sonar unit is a high quality

sonar designed for both professional and novice fishermen. All of our

sonars have an automatic feature that finds and displays the bottom, fish,

structure, and more! All you have to do is press the on key. However, if

you wish to fine tune the unit, all you have to do is press the menu key. The

Strata series has powerful features available through easy-to-use menus.

To get started with your Eagle unit, first read the installation section. This

is where it all begins. Improper installation can cause problems down the

road. After you’ve read the instructions, install the unit, then read the rest

of the manual. The more you know about your unit, the better it will perform

for you. Take this manual for reference when you head for the water.

NOTICE!

The storage temperature for your unit is from -4 degrees to +167 degrees

Fahrenheit (-20 degrees to +75 degrees Celcius). Extended storage in tempera-

tures 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 customer service department or your local service center.

Transducer Installation

The transducer included with your sonar is a transom mount transducer

The “kick-up” mounting bracket helps 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 in place without tools.

Read this manual carefully before attempting the installation. Determine

which of the mounting positions is right for your boat. Use extreme care

if mounting the transducer inside the hull, since once it is epoxied into

position, the transducer usually cannot be removed. Remember, the

transducer location is the most critical part of a sonar installation.

Location - General

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 will

show on the sonar’s display in the form of random lines or dots

whenever the boat is moving.

2. The transducer should be installed with it’s face pointing straight

down, if possible.

3. If the transducer is mounted on the transom, make certain 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 interference with the propeller. Typically, the

transducer should be mounted as deep in the water as possible. This

increases the chance that it will be in the water in high speed and

reduces the possiblity of air bubble interference.

4. If possible, route the transducer cable away from other wiring on the

boat. Electrical noise from engine wiring, bilge pumps, and areators

can be displayed on the sonar’s screen. Use caution when routing

the transducer cable around these wires.

5

Shoot-thru-hull v.s. Transom Mounting

(Strata 128 and Strata 128 Plus Only)

Typically, shoot-thru-hull installations give excellent high speed opera-

tion and good to excellent depth capability. There is no possibility of

damage from floating objects. It can't be knocked off when docking or

loading on the trailer.

However, the shoot-thru-hull installation does have its drawbacks. One,

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 layup and construction. Two, the angle

of the transducer cannot be adjusted for the best fish arches. This can

be a problem on some hulls that sit with the bow high when at rest or at

slow trolling speeds. Follow the procedure listed in the shoot-thru-hull

installation section in this manual to determine if you can satisfactorily

shoot through the hull.

DOT

Transducer Assembly and Mounting - All Units

The best way to install this 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. Press the two small plastic ratchets into the sides of the metal bracket

as shown below. 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 fourteen (14) degree transom. Most

outboard and stern-drive transoms have a fourteen degree angle.

6

2. Slide the transducer between the two ratchets. Temporally 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 ratch-

ets 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 letter until you can

place the transducer on the transom correctly.

3. Once you determine the correct position for the ratchets, assemble

the transducer as shown at left. Don't tighten the lock nut at this time.

4. Hold the transducer and bracket assembly against the transom. The

transducer should be roughly parallel to the ground. The bottom of the

transducer bracket should be in line with the bottom of the hull.

Don't

let the bracket extend below the hull!

Mark the center of the slots for

the mounting holes. Drill two 5/32" holes in the marked locations for

the #10 screws supplied with the transducer.

5. Remove the transducer from the bracket and re-assemble it with the

cable passing through the bracket over the bolt as shown above. At-

tach the transducer to the transom. Slide the transducer up or down

until it’s aligned properly on the transom as shown above. Tighten the

bracket’s mounting screws. Adjust the transducer so that it’s parallel to

the ground and tighten the lock nut until it touches the flat 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 to the sonar unit. Make certain to leave

some slack inthe cable at the transducer as shown above. If possible,

route the transducer cable away from other wiring on the boat. Electri-

cal 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.

IMPORTANT!

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.

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, hope-

fully below the turbulence causing the noise. Don't allow the trans-

ducer bracket to go below the bottom of the hull!

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. 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 certain 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.

1. Attach the TMB-S bracket to the transducer as shown below using the

hardware supplied with the transducer. (Note: The internal tooth washer

is supplied with the TMB-S.)

SHOOT-THRU-HULL

(Strata 128 and Strata 128 Plus Only)

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 success-

ful 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. For example, some

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 fiber-

glass. 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.

To choose the proper location for thru-hull mounting, anchor the boat in

60 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. Adjust the sensitivity and range controls until a

second bottom echo is seen on the display. (you will need to turn both

automatic and ASP off.) Don’t touch the controls once they’ve been set.

Next, take the transducer out of the water and place it in the water in the

sump of the boat. Observe the sonar signal to see if there is a notice-

able decrease in sensitivity. The second bottom signal may disappear

and the bottom signal may decrease in intensity. Move the transducer

around to find the best location. If the sensitivity control has to be

increased greatly to compensate, then the transducer should be

mounted on the outside of the hull. If not, then mark the location that

shot through the hull the best and follow the instructions on the next

pages for a shoot-thru-hull mounting.

2. Follow the instructions on the epoxy package and mix it thoroughly.

Do not mix it too fast, as it will cause bubbles to form in the epoxy.

(NOTE! Use only the epoxies specified on the inside front cover of this

manual! Failure to use one of these epoxies may result in poor sonar

performance!) Apply a small amount on the face of the transducer as

shown above, then spread a small amount onto the sanded area on the

1. Make certain 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 surface of the hull must be flat so the entire

transducer face is in contact with the hull prior to bonding.

hull. Place the transducer into the epoxy, twisting and turning it to force

any air bubbles out from under the transducer face. The face of the

transducer should be parallel with the hull, with a minimum amount of

epoxy between the hull and transducer. After the epoxy dries, route the

cable to the sonar unit.

Fish Arches

If you do not get good fish arches on your display, it could be 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 the the arch is printed, then the nose of the

transducer is angled too far down and needs to be raised.

POWER CONNECTIONS - Permanent mount units only

This unit works from a 12 volt DC system only. For the best results, run the

power cable directly to the boat’s battery. Keep the power cable away from

other boat wiring, especially the engine’s wires. This will give the best

isolation from electrical noise. If the supplied cable is not long enough to

reach the battery, splice #18 gauge insulated wire to it. You can attach the

power cable to an accessory or power buss, however, you may have

problems with electrical interference. Make certain to attach the in-line fuse

holder to the positive lead as close to the battery or terminal strip as

possible. This will protect both the unit and the power cable in the event of

a short. Use a 3-amp fuse.

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 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.

Bracket Installation - Permanent mount units only

You can install the sonar unit on the top of a dash or from an overhead with

the supplied bracket. It can also be installed in the dash with an optional

IDA-3 mounting kit. If you use the supplied 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.

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 hole in the dash for the power and transducer cables. The best

location for this hole is immediately under the gimbal bracket. This way, the

bracket covers the hole. The smallest hole the power and transducer cable

connectors can pass through is 5/8". After drilling the hole, pass the power/

transducer connector up through the hole from under the dash. Slide the

bracket over the hole, then route the cables out the slot in the back of the

bracket. Finally, fasten the bracket to the dash.

Attach the unit to the gimbal bracket using the supplied gimbal knobs and

washers as shown above.

INSTALLING THE BATTERIES

Release the latch on the front of the battery case. Open the compartment

and install four "D" cell batteries into the adapter. For the longest life, we

recommend you use alkaline batteries. This battery case will also hold one

rechargable battery instead of the "D" cells. See the enclosed coupon for

more information on the rechargable battery.

"D" CELL BATTERY

After installing the batteries, close the case and plug the power cable on

the battery case into the Strata 128 Portable. Turn the sonar unit on. If it

doesn't work, make certain the battery terminals are making good contact

against the battery contacts. Also check the wiring connections on the D-

cell battery adapter. The red wire on the power cable should be attached

to the red wire on the D-cell battery adapter and the power cable's black

wire should be connected to the black wire on the D-cell battery adapter.

If it still doesn't work, check the battery voltage. Most of the complaints we

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

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.

receive about portable units result from stale batteries. Make certain the

ones you buy are fresh. Always remove batteries from the battery

compartment before storing the unit as dead batteries can leak and

corrode the contacts.

In cold weather the efficiency of dry cell batteries drops with the tempera-

ture. We find it a good idea to have the sonar unit good and warm along with

the batteries before we leave home. 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.

Don't ever heat the batteries over an open flame or direct hot air onto them.

A fire or explosion could result.

Clean the chosen area of the hull before attaching the suction cup. Locate

the transducer on the hull as shown below. Don't allow the bracket to go

below the hull, as water pressure against it can cause the suction cup to

come off at speed. 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. Plug the transducer connector into the unit and your

portable sonar is now ready for use.

HULL

SPEED/TEMPERATURE SENSORS

The Strata Plus and StrataView can use up to three temperature sensors

which can monitor surface water, live well, air, and virtually any other

temperature. You do need to be careful when purchasing the temperature

sensors, however. Each temperature sensor has its own "address". The

sensors are labeled "Water", "T-2" (or Temp-2), and "T-3" (or Temp-3). If

you want two (or more) temperature readings, you'll need to use the proper

sensors. For example, you can't use two T-3 sensors. The sensors that will

fit these units are:

TS-1BK One sensor for "Water" temperature display.

TS-2BK One sensor for "T-2" temperature display.

TS-3BK One sensor for "T-3" temperature display.

TS-12BK Two sensors for "Water" and "T-2" temperature displays.

ST-TBK One speed sensor and one temperature sensor for

"Speed" and "Water" displays. (comes with Strata Plus)

You can combine these sensors in many combinations. See the list on the

following page for temperature and speed sensor combinations.

MENU FWD / MENU REV

These sonar units have many features that are accessed with the menu

keys. The MENU FWD key moves forward through the menus, the MENU

REV key moves backward. To see the first menu, simply press either

MENU key. To see the other menus, press a MENU key repeatedly.

UP and DOWN ARROWS

Use these keys to adjust virtually every feature and function on the unit.

NOTE: The up arrow key also stops the chart when no menus are

displayed. In other words, anytime you wish to stop the chart, first make

certain no menu is on the screen. Now press the up arrow key. The chart

freezes and the word “STOP” appears at the top of the screen. To start the

chart, press the up arrow key again or the PWR/CLEAR key.

DISPLAY - General

The lights flash for about ten seconds when the unit is turned on. Two

menus appear, one after the other. The menus are the lights (BACK

LIGHT) and a feet-meter selection (FEET/METER). To turn the lights on,

press the up arrow key. To switch from feet to meters, press the down

arrow key when the proper menu appears. The menus disappear after a

few seconds. If you don’t want to wait, press the

PWR key to clear the menus from the screen.

When the sonar unit is first turned on, the display

appears similar to the one at right. The unit is in

the automatic mode and the Fish ID feature is

on. The depth range shows on the left side of the

screen. On the screen at right, the range is from

0 to 60 feet and the bottom depth is 48.6 feet.
