The Garmin GT56UHD is a high-performance all‑in‑one transducer designed to turn your compatible Garmin chartplotter into a razor‑sharp fish‑finding system, with ultra‑clear detail below and to both sides of your boat. It is built for anglers who want serious imaging performance in shallow and deep water, without juggling multiple transducers.
Premium overview
Unlock Ultra High‑Definition ClearVü and SideVü scanning in one compact, powerful package with the Garmin GT56UHD. From pinpointing isolated structure to separating individual fish in a school, this transducer gives you the kind of detail that turns “maybe” spots into guaranteed waypoints. Mount it on the transom or trolling motor and instantly upgrade your sonar to a level normally reserved for top‑end tournament setups.
Key performance features
• All‑in‑one UHD scanning + CHIRP
Combines high‑wide CHIRP traditional sonar with Ultra High‑Definition ClearVü and SideVü in a single housing, reducing clutter on your transom and simplifying installation.
• Ultra High‑Definition clarity
Multiple UHD frequencies (455 kHz, 800 kHz and 1,000 kHz) deliver crisp images of structure, bottom composition and fish, with target separation sharp enough to distinguish individual fish and even size differences.
• Serious power and range
Up to 800 ft traditional CHIRP depth capability with powerful ClearVü coverage below the boat and SideVü ranges extended by roughly 20% compared to previous models, so you see more water in a single pass.
• High‑contrast vivid color palettes
Works with Garmin’s vivid scanning color palettes, making fish and structure pop off the screen so you can read your sonar at a glance, even in bright sun.
Compatibility and mounting
• Wide Garmin compatibility
Designed for use with selected ECHOMAP UHD / UHD2, ECHOMAP Ultra and GPSMAP xsv chartplotter series, giving them full UHD ClearVü and SideVü capability.
• Flexible mounting options included
Supplied as a transom‑mount unit with a 12‑pin plug, 25 ft cable, and hardware for both transom and trolling‑motor installations, plus built‑in depth and temperature sensors
