Transducers

The transducer acts as the eyes and ears of your new sonar. Proper transducer selection and installation are critical to the operation of your unit.

The transducer transmits sound waves toward the bottom in a cone shape. The larger the cone angle the larger the coverage area at a given depth. While it is good to see as large of an area as possible, it is best to select a transducer that suits the water that you are on.

A wide cone angle transducer works best in shallow water. The wide cone angle provides a large coverage area, but at a decreased bottom resolution. In deeper water this can result in a large dead zone where fish cannot be seen.

A narrow cone angle transducer is better suited to deep-water installa- tions. The narrow cone angle provides a smaller viewing area (compared to a wide cone angle transducer at the same depth) with improved bottom resolution and a smaller dead zone.

Included in the Optional Package is a 20° cone angle, temperature sens- ing, transom mount transducer. This transducer provides good all-around performance. A variety of optional transducers are available from your local dealer or GARMIN.
