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.

Included in the Optional Package is a 200/50kHz frequency (10°/40° cone angle), depth and temperature sensing, transom mount transducer. This transducer provides good all-around performance. Other optional dual frequency transducers are available from your local dealer or GARMIN.

The transducer transmits sound waves toward the bottom in a cone shape. The wider 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 frequency setting that suits the water that you are on.

With a dual frequency transducer, you may select either a 200kHz frequency, a 50kHz frequency or both. The 50kHz frequency setting provides a wide cone angle. This wide cone angle produces a large coverage area, but less detailed bottom resolution. In areas where bottom contours change quickly, this can result in “dead zones” where fish cannot be seen.

In contrast, the 200kHz frequency setting provides a narrow cone angle. This narrow cone angle produces a smaller viewing area (compared to a wide cone angle at the same depth), but with improved bottom resolution and a smaller dead zone.

The Dual frequency setting will provide you the most accurate depth and fish returns by transmitting signals at both 200kHz and 50kHz.
