Meet the Garmin GT54UHD-TM Ultra HD Transom Mount Transducer — an all-in-one sonar powerhouse designed to deliver breathtaking underwater clarity. This transducer combines Ultra High-Definition scanning sonar with high-wide CHIRP traditional sonar, giving you unmatched detail of fish, structure, and terrain up to 200 feet below your boat with 800 kHz ClearVü and expansive SideVü views.

• Ultra High-Definition ClearVü imaging to 200' depth at 800 kHz for crystal-clear detail of fish, brush, trees, and rocks.
• Ultra High-Definition SideVü coverage up to 125' to each side (250' total) at depths up to 30', with a 1.2 MHz SideVü option for exceptionally crisp side-scans.
• Extended-range SideVü two-frequency settings (455/1200 kHz) provide options for extended range up to 500' per side, helping you see around cover and structure from farther away.
• Traditional CHIRP High Wide sonar (150-240 kHz) with CHIRP range 760-880 kHz delivers strong target separation and definition.
• Powerful, all-in-one design with included transom and trolling motor mounts for easy installation on most vessels.
• Compatibility designed to work with GPSMAP 8400xsv / 8600xsv chartplotter/sonar combos for seamless integration and display.
• Depth and temperature sensing provide additional data for accurate fishing conditions, with a 12-pin orange connector and a 20 ft cable for flexible mounting.
• Mounting versatility supports 0°–70° transom angles, ensuring optimal performance on a wide range of boats.
