About the L750 Fishfinder

The L750 Fishfinder 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 L750 Fishfinder 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 L750 Fishfinder to be one of the most useful
devices on your boat.

System Components

The L750 Fishfinder consists of a compact display unit connected to a
transducer. The transducer is attached to the boat and extends into the
water.
