The Garmin GT56UHD-TM is an all-in-one transom-mount transducer that combines Ultra HD ClearVü™ and Ultra HD SideVü™ scanning sonar with a traditional high/wide CHIRP sonar. The transducer is designed for anglers who want maximum detail, precise target separation, and high versatility, whether fishing in shallow or deep water.
With Ultra HD scanning sonar, you get extremely sharp images of structures and fish directly below and to the sides of the boat, while the traditional high/wide CHIRP sonar (150–240 kHz) delivers clear fish arches and stable depth readings down to 244 meters (800 ft) in freshwater.
The GT56UHD-TM supports 455 kHz, 800 kHz, and 1,000 kHz, so you can always choose the optimal frequency for your fishing spots. The transducer comes with transom and trolling motor mounting hardware, features a fast-responding temperature sensor, and is compatible with modern Garmin chartplotters with a 12-pin transducer input.
