Garmin GT56UHD-TM Transducer

Part Number: 010-13073-00

An all-in-one transducer offering ultimate versatility with Ultra High-Definition ClearVü and SideVü scanning sonars, high wide CHIRP traditional sonar, and multiple frequency options — all in a single transom-mount unit.

Sonar Technologies

• Ultra High-Definition ClearVü Scanning Sonar: Brilliant image clarity of structure and fish directly below your boat at greater depths than standard high-frequency scanning sonars. Downward-facing element puts more power on targets.
• Ultra High-Definition SideVü Scanning Sonar: Stunningly clear images of structure and fish off to the sides of your boat. 20% greater range at 1,000 kHz vs previous generation.
• High Wide CHIRP Traditional Sonar: Remarkably clear target separation and definition to depths of 244 m (800 ft) in freshwater.
• Multiple Scanning Frequencies: 455 kHz, 800 kHz, and 1,000 kHz — optimised for all depths and water conditions.
• Vivid Colour Palettes: High-contrast colour rendering makes it easier to distinguish targets and structure at a glance.
