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.
FishFinder 465
Features and functions
Fish symbols and alarms
Theunit provides fast,positiveidentifica-
tion of fish in the water. It even indicates
the size of a fish using eight different fish
symbols. The 465 includes alarms for
shallow warning,deepwarningand fish
warning.
Clear LCD display
TheFishFinder displayproducescontinu-
ouspictures of bottom conditions and fish
in the water. The display unit may be
turnedor tiltedto the bestviewingangle.
TheFishFinder unitcan beeasily
removed from the boat for storage in a
safe place.
Totally waterproof
TheFishFinder 465meets U.S.Coast

it can stand up to the hard service
requiredon small boats. Therugged
constructionandsophisticated sealing
methods used in this unit will ensure
many years of reliable service.
