Echo Sounding
How it Works
◆Your eyes underwater
An “echo sounder” or “sonar” unit sends high-frequency sound waves down into the
water below a boat. These sounds hit the bottom of the lake or sea and bounce back.
The display unit measures the time delay as the signal goes out and returns. The
FishFinder uses this information to display a graphic image of the bottom conditions.
The system also uses this same principle to detect fish or other objects in the water,
and display their size and location. This display is like a “window” which allows you to
look into the underwater world.
◆About the transducer
The transducer transmits the sound waves down into the
water. It also receives the waves as they return. One
type of transducer can be mounted on the transom
of the boat, as shown here. Other types of
transducers can be installed through a hole in
the hull, or mounted inside the hull.
◆The Sidelooker
transducer
The optional Sidelooker is a
special type of transducer
which allows the Fish-
Finder to detect fish beside
the boat.The Sidelooker
produces two powerful hori-
zontal beams which ex-
tend to either side, just
below the surface of the
water.
The Sidelooker transducer uses a
special plastic material called “PVDF,”
which was developed by Raytheon
Naval Systems.This allows the Side-
looker to give you the clearest possible
picture of conditions underwater.

“Out of the box” operation
Becauseofanumber ofautomatic fea-
tures, the FishFinder 465 unit is ready to
operate“right out of the box.” This unit in-
cludesautomatic settings forthemost
important controls – range,sensitivity, and
zoom. Because these settings are
automatic,the FishFinder will provideuse-
ful displays right from the start. Once you
becomemore comfortablewiththe
operationof the unit, you can adjustthese
settings.
Excellent ability to find fish
To a sonar unit like the FishFinder, the
waterincludes a lot of background“noise.”
Thereare manyconditionswhich could
confuse a sonar unit – bubbles and wakes
inthe water, temperaturedifferencesbe-
tween water layers, and so on. It can be
difficult for a sonar unit to detect fish
againstthisbackgroundofnoise.
Because of its advanced circuitry, the 465
isespecially good at telling the difference.
Dual frequency operation
“Frequency”is a measure of how fast the
sound waves change or“vibrate.” The
FishFinder uses sound waves with two
different frequencies – 50 kHz and 200
kHz. The 50 kHz frequency scans a wide
area, and penetrates the water well. This
frequency is best for use in deep water.
The 200 kHz frequency scans a narrower
areabutproducesa moredetailed view.
This frequency is best for seeing fish near
the bottom, or fish which are close
together. The FishFinder can also use
both frequencies at the same time. This
providesgood depth penetrationandgood
detailin the display.

About the FishFinder 465
The FishFinder 465 is a system that uses sound waves (“sonar”) to
detect fish and show the bottom of a lake or sea. The system includes a
transducer and a display unit, connected by a cable. The transducer
sends high-frequency sound waves down into the water. These sounds
strike fish, the bottom, or other objects in the water, and return as
echoes. The FishFinder then interprets these echoes and presents a
display.
The FishFinder 465 can handle many different jobs:
• detect the presence of fish below the boat
• trigger an alarm when fish are found
• measure the depth of the water
• set alarms for minimum and maximum depth
• show the shape of the bottom
• determine whether the seabed is hard or soft
• measure the speed of the boat and the distance traveled
• show the water temperature
We are sure you will find the FishFinder 465 to be one of the most useful
devices on your boat.

Installation
2 – Installation
The installation process has four parts:
• Mounting the transducer
• Mounting the display unit
• Connecting the cables for the transducer and power supply
• Calibrating the display unit
About the Transducer
Several different kinds of transducers can be used with this unit. The
transom-mount type is used most often. Other types are shown in Fig. 2-
1.
Most transducer types can measure the water depth. Some of the
transducers also have two other sensors: a paddle wheel which detects
the speed of the boat, and a sensor for the water temperature. The
display unit uses the speed information to calculate the distance the boat
has traveled.
The transducer is very important to the operation of the FishFinder. It is
also important that you mount the transducer correctly. The transducer
will give the most reliable readings if it looks into water which is smooth
and undisturbed. If you place the transducer so bubbles or turbulence
flow across the face of the unit, the system may give inaccurate readings.
There are three important rules for placing any type of transducer:
• The transducer should be continuously covered by water when the
boat is moving. (If the transducer is mounted near the side of the
boat, it may be exposed when the boat is turning.)
• The transducer should be placed where turbulence or bubbles will
not pass directly over the face of the unit. Don’t place the transducer
behind any running strakes, intakes, or thru-hull fittings which create
turbulence.
• The transducer should be mounted where it will not be affected by
the wash from the propeller(s).

Types
Selecting the Correct Type of Transducer
Before you begin the installation, double-check to be sure you have the
correct type of transducer. Each kind of transducer is designed for a
particular type of use. In this manual we will include detailed mounting
instructions for the transom-mount transducer. We will also include some
general information on the other types. For detailed information on these
other transducers, see the instructions which are packaged with the unit.
Use a transom-mount transducer if –
your boat has an outboard or inboard-outboard engine(s) only.This type
of transducer must be mounted ahead of or beside the propeller(s). Don’t
use this type of transducer on a boat with a straight-shaft inboard engine.
Use a thru-hull transducer if –
your boat has a straight-shaft inboard engine. This type of transducer is
installed in a hole drilled through the hull.
Use an in-hull transducer if –
you have a high-speed boat or if, for some reason, you cannot use a
transom-mount or thru-hull transducer.The hull may be no more than 1"
thick.

Bracket
Use a trolling motor transducer if –
you want to attach the transducer to a trolling motor.
Use a Sidelooker transducer if –
you need a way of searching for fish on either side of the boat. This type
of transducer is attached to the bracket of the transom-mount transducer.
Assembling the Transducer Bracket
Fit together the two parts of the transducer bracket as shown in Fig. 2-2.
When the installation is complete, the parts snap together as shown.
Positioning the Transom-Mount Transducer
Begin by finding the best location for the mounting bracket. Here are the
rules:
• If your boat has one propeller (outboard or inboard-outboard), mount
the transducer about 18” (455 mm) to the side of the centerline of
the boat. See Fig. 2-3. Choose the side that is on the downstroke of
the propeller. (This is usually the starboard side of the boat.) This
will reduce any interference caused by air bubbles.
• If your boat has twin propellers (outboard or inboard-outboard),
place the transducer near the centerline of the boat.
• If the propeller can be turned to steer the boat, allow at least 2" (50
mm) beyond the swing radius of the propeller.This will prevent the

propeller from damaging the transducer when it is turned.
• Do not mount the transducer behind any hull fittings, intakes, or
other parts which extend from the hull.These may cause turbulence
or air bubbles.
• The bracket has a quick-release mechanism. This prevents damage
by allowing the transducer to flip up if it hits any debris or the bottom.
See Fig. 2-4. Allow enough clearance above the transducer so that it
can swing upward completely.This is about 10" (254 mm) measured
from the bottom of the transom.

Installation
• If the boat will be carried on a trailer, be sure the transducer will not
hit any rollers, bunks or fittings on the trailer.
Mounting the Transom-Mount Transducer
1. On a boat with a fiberglass hull, the leading edge of the transducer
should extend 1/8" (3.2 mm) to 1/4" (6 mm) below the bottom edge
of the hull. See Fig. 2-5. On an aluminum hull, the transducer should
extend a bit more – 1/4" (6 mm) to 3/8" (9 mm). If the boat will be
operated at high speeds, the transducer may be mounted closer to
the centerline of the hull.
2. The lower surface of the transducer should tilt down toward the rear
at a slight angle (2° to 5°). The mounting bracket includes a wedge.
Depending on the angle of the transom on your boat, you may need
this wedge to get the correct angle for the bottom of the transducer.
3. Looking at the rear of the boat, be sure the bracket is vertical
(perpendicular to the water line).
4. Hold the bracket (and the wedge, if used) against the transom and
trace the positions of the screw slots.
5. Remove the bracket. See Fig. 2-6.The screws in the outer slots
should be placed about 1/4" (6 mm) up from the bottom of each slot.
The screw in the center slot should be placed 1/4” (6 mm) down from
the top. (This will allow you to adjust the bracket up or down a bit.)
Drill pilot holes 3/4" (19.1 mm) deep. Use a 9/64" (3.6 mm) drill bit.
To prevent drilling too deeply, wrap masking tape around the drill bit
about 7/8" (22 mm) from the tip. Drill in only as far as the tape
marker.
If you are attaching the bracket to a fiberglass hull, you can minimize
any surface cracking of the gel coat. Before drilling each pilot hole,
drill a shallow hole (chamfer) at each location about 1/16" (1.5 mm)
deep. Use a 1/4" (6 mm) drill bit.
6. Attach the bracket to the hull using the panhead screws with flat
washers. Before you tighten the screws, apply a good-quality marine
sealant to the pilot holes.This will protect the hull from water
penetration.
Do not tighten the screws completely yet.
7. Move the bracket up or down so that the leading edge of the
transducer has the clearance shown in Fig. 2-5.
8. Once the bracket is in the correct position, you can tighten the screws.
