About the FishFinder L470
The FishFinder L470 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 L470 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 L470 to be one of the most useful
devices on your boat.

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 style, used most often, and in-hull types are shown in Fig.2-1.
Besides measuring depth, the transducers have two other sensors: a
paddle wheel which detects the speed of the boat, and a sensor for the
water temperature. An optional transducer, the Sidelooker, detects
objects by looking out to the sides of the boat.
Since the transducer is very important to the operation of the FishFinder,
it is vital that the transducer be mounted 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 when mounting 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).
