Garmin GT 56UHD-TM

Garmin GT 56UHD-TM is an all-in-one transducer that offers ultimate versatility, featuring Ultra High-Definition ClearVü and SideVü scanning sonars, high wide CHIRP traditional sonar and more, so you can spend more time catching fish.

Ultra High-Definition Clearvü Scanning Sonar
Get brilliant image clarity of structure and fish below your boat at greater depths than other high-frequency scanning sonars. It puts more power on targets via a downward-facing element.

Ultra High-Definition Sidevü Scanning Sonar
See everything the first time with stunningly clear images of structure and fish off to the sides of your boat. SideVü sonar now has 20% greater range at 1,000 kHz, so you can see even farther than before.

High Wide Chirp Traditional Sonar
Experience remarkably clear target separation and definition up to 800’ below your boat.

Multiple Scanning Sonar Frequencies
Use the perfect frequency for the waters you’re fishing. This transducer delivers 455 kHz, 800 kHz and 1,000 kHz for top performances at all depths.

Vivid Color Palettes
High-contrast vivid scanning sonar color palettes make it easier than ever to distinguish targets and structure.

Mounting Options 
Everyone’s setup is different. That’s why we’ve included transom and trolling motor mounting hardware.
