INSTALLATION PREPARATION
INSTALLATION OVERVIEW
The transducer converts electrical energy from the transmitter into mechanical pulses or sound waves. The transducer also receives the reflected sound waves and converts them back into electrical signals for display on the control head. It should be installed in contact with the surface of the water in an area that has smooth water flow - usually on the transom of the boat. There are several mounting options for the transducer. Review the
following section to determine the method that works for you and your boat.

Transducer

The transom installation, which is the most
widely used, places the transducer on the outside of the boat hull. This technique produces the least signal loss, and provides a way to adjust the
transducer after installation. The mounting
hardware included is designed to protect both the boat and the transducer should the boat strike debris in the water or when trailering.
