-
Mounting options: Flexible mounting with hardware for transom, trolling motor, and thru-hull installations; supports 0°–70° transom angles
-
Transducer specifications: 12-pin transducer with 25 ft cable; depth and temperature sensing built in
-
What’s in the box: GT56UHD-TH transducer, stainless steel stem, fairing block, isolation plate and bushings, extension cable, mounting hardware, and documentation
With this transducer, you gain a comprehensive view of what lies beneath and to the sides of your boat. The downward-facing element focuses energy for crisper returns at depth, while the combination of CHIRP and high-resolution imaging helps you identify fish, structure, and bottom detail with confidence. The flexible mounting options simplify installation on a wide range of boats, letting you tailor your sonar setup to your fishing style and navigation needs.
