Get Ultra High-Definition sonar with the Garmin GT56UHD-TM Transom Mount Transducer. This versatile, all-in-one unit blends ClearVü, SideVü, and traditional CHIRP to reveal color and sharp target separation for structures and fish around your boat, with mounting hardware suitable for both transoms and trolling motors.
-
Imaging modes: Combines traditional CHIRP with ClearVü and SideVü for comprehensive underwater views of structure and fish.
-
Multi-frequency support: Traditional High-wide CHIRP (150–240 kHz); ClearVü/SideVü at 455 kHz (425–485), 800 kHz (790–850), and 1000 kHz (940–1100).
-
Power output: Traditional 350 W; ClearVü/SideVü 500 W for crisp, high-contrast imagery.
-
Beamwidth and resolution: Traditional CHIRP beamwidth 24–16 degrees; ClearVü/SideVü provide frequency-dependent patterns and resolutions (0.52 x 52 at 1000 kHz, 0.64 x 35 at 800 kHz, 1.1 x 52 at 455 kHz; SideVü patterns mirror these values).
-
Depth performance: Traditional up to 800 ft freshwater; ClearVü up to 400 ft; SideVü up to 500 ft, with imagery/target definition to about 800 ft below the surface.
-
Depth and temperature data: Real-time depth and temperature readings to help you interpret conditions on the water.
-
Cable and connectors: 12-pin connector with 25 ft cable for flexible installation.
-
Mounting flexibility: Includes hardware for both transom and trolling motor mounting; supports deadrise/transom angles from 0° to 70° to fit a wide range of boats.
With the GT56UHD-TM, you gain clear visualization of structure, cover, and fish, plus real-time depth and temperature readings. The combination of Ultra High-Definition ClearVü and SideVü with powerful CHIRP imaging helps differentiate targets from clutter, plan your approach, and fish with confidence in a variety of water conditions. Its mounting versatility and robust connectivity simplify installation on both traditional transoms and trolling motors, making it a reliable choice for anglers seeking precise underwater insight.
