INTRODUCTION
Thank you for purchasing an Eagle sonar. Your Magna or Magna III Plus
is a high quality sonar designed for both professional and novice fishermen. These units 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 Magna 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.

INSTALLATION - Bracket
You can install the Magna III 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 Magna III'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 Magna III 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 Magna IIII's power and
transducer cable connectors can pass through is 3/4". However, you can’t
pass a power or transducer connector and another cable through a 5/8"
hole. Therefore, after drilling the hole, pass the transducer connector up
through the hole from under the dash. Then drop the power cable down
from the front side of the dash. After installing the transducer, route its
cable to the unit by passing it through the hole from under the dash. Slide
the bracket over the hole, then route the transducer and power cables out
the slot in the back of the bracket. Finally, fasten the bracket to the dash.

POWER CONNECTIONS
The Magna III 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. If you do
extend the power cable, make certain to attach the in-line fuse holder
supplied with the Magna III to the battery or power source. This will protect
both the unit and the power cable in the event of a short. Use only a 3-amp
fuse.
You can also attach the power cable to an accessory or power buss,
however, you may have problems with electrical interference.
These units have 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.

SPEED/TEMPERATURE SENSOR INSTALLATION (Magna III Plus Only)
Mount the speed/temp sensor on the boat’s transom in a location where the
flow of water is the smoothest. There should be a minimum of turbulence
and air bubbles in the chosen location. The port (left) side of the transom
is preferred, however, the starboard (right) side can be used if necessary.
Do not mount the speed sensor behind strakes, ribs, or thru-hull fittings.
These will disturb the flow of water to the speed sensor. In a typical
installation, the speed sensor is mounted six to twelve inches from the
centerline of the hull. The sensor must always be in the water to function
properly. Make certain the chosen location is in the water even at high
speed or when the boat is on plane.
Once you determine the proper location, place the sensor on the transom.
Make certain the sensor’s bottom is flush with the bottom of the hull. Mark
the transom in four places, two in each slot. Drill a 5/32" mounting hole at
each location. Mount the sensor to the hull with four #10 stainless steel
screws. Use a good grade of caulking compound to seal the screws.
Adjust the sensor so it is flush with the bottom of the hull and tighten the
screws. If the base of the transom has a radius, fill the gap between the
transom and the sensor with caulking compound. This will help ensure a
smooth water flow.
Route the sensor cable to the in-line connector on the Magna Plus’ power
cable. The speed/temp sensor is now ready for use.

MAGNA III PORTABLE ASSEMBLY
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 Magna III Portable. Plug the adapter cable into
the back of the sonar unit. 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 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 temperature. We find it a good idea to have the Magna III Portable 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.
PORTABLE TRANSDUCER ASSEMBLY
Assemble the transducer and bracket as shown below. Attach the
transducer to the bracket with the supplied hardware. Make certain there
is one washer on each side of the transducer, inside the bracket. Slide the
other washer over the end of the bolt and thread the nut onto it. Screw the
suction cup onto the bracket using the supplied screw and flat washer. Tie
the nylon cord through the hole in the top of the bracket. When using this
transducer, tie the other end of the nylon cord to the boat. This will help
prevent the loss of the transducer if it comes off the boat.

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 "Y" power cable on
the Magna III. Your portable sonar is now ready for use.
HULL
PERMANENT MOUNT TRANSDUCER INSTALLATION
The HS-WSBK supplied with your Magna III is a transom mount transducer. It can be installed on any outboard or stern-drive
(inboard\outboard) powered boat. It can also be permanently installed
inside the boat to "shoot-through" the hull on some fiberglass boats.
The “kick-up” mounting bracket helps prevent damage if the transducer
strikes an object while the boat is moving. If the transducer does “kickup”, the bracket can easily be pushed back in place without tools.
Read the enclosed transducer installation 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. If it isn’t done properly, the sonar can’t
perform at it’s designed potential.

freezes and the word “STOP” appears at the top of the screen. To start the
chart, press the up arrow key again.
DISPLAY - General
The lights flash for about ten seconds when the Magna III is turned on.
Three menus appear, one after the other. The menus are the lights
(LAMP), feet-meter selection (FEET/METER), and contrast adjustment
(DARK/LIGHT). 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. To adjust the contrast,
wait for the DARK/LIGHT menu to appear.
Now press the up arrow key to darken the
screen, the down arrow to lighten it. The
menus disappear after a few seconds. If you
don’t want to wait, press the ON/CLEAR key
to clear the menus from the screen.
When the Magna III is first turned on, the
display appears similar to the one at right.
The unit is in the automatic mode and the Fish
10
ID feature is on. The depth range displays on the upper left side of the
screen. On the screen at the bottom of the previous page, the range is from
0 to 60 feet and the bottom depth is 37.3 feet.
OPERATION
MENUS
The Magna III and Magna III Plus use menus to guide you through the unit’s
functions and features. The menu key accesses these features, allowing
you to customize the unit to your particular needs and water conditions. All
you have to do to leave one menu and enter another is press the menu key
repeatedly. If you ever get lost in the menus, simply press the ON/CLEAR
key. This clears the menus from the screen.
Menus change depending on the mode the unit is in. For example, if the
automatic mode is turned off, the sensitivity menu changes from “AUTO
SENS” to “MAN SENS.” Other messages may appear in menu boxes or
new menus can appear, again depending on previous selections.
On the screen shown on the previous page, the lamp menu is showing.
AUTOMATIC
When the Magna III is first turned on, the
automatic feature is enabled. This feature
automatically adjusts the unit’s range and
sensitivity according to water conditions. It
always keeps the bottom depth displayed in
the lower portion of the screen.
To turn the automatic feature off, press the
menu key until the AUTO/MAN menu appears. Now press the down arrow key. This
highlights the letters “MAN.” The unit is now
in the manual mode. Wait a few seconds and
the menu will scroll off the screen’s left side.
Pressing the ON/CLEAR key also clears it. To turn the automatic feature
on again, repeat the above steps, except this time press the up arrow key.
RANGE
