Optional Transducers

The transducer acts as the eyes and ears of your new sonar. 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.

Proper transducer selection and installation are critical to the operation of your unit. Since mounting locations vary, see your local dealer or contact Garmin Product Support for further information. A full list of transducers can be found at www.garmin.com.
