The Garmin GT56UHD-THP Transducer Thru-Hull Pair is a dual-transducer kit designed for serious anglers who demand ultra-sharp imaging and flexible installation options. It delivers comprehensive, color-rich sonar with Ultra High-Definition scanning alongside traditional CHIRP across multiple frequencies.
-
Imaging Suite: Ultra High-Definition scanning sonar with ClearVü and SideVü, plus traditional CHIRP, all in one package.
-
Frequencies & Image Detail: Multi-frequency support—Traditional CHIRP 150–240 kHz; ClearVü/SideVü at 455 kHz (425–485 kHz), 800 kHz (790–850 kHz), and 1000 kHz (940–1100 kHz)—for precise imaging in varying conditions.
-
Depth & Coverage: Traditional depth up to 800 ft in freshwater; ClearVü up to 400 ft; SideVü up to 500 ft.
-
Power Output: Traditional mode 350 W; ClearVü/SideVü 500 W to maintain target separation and detail.
-
Beamwidth: Traditional CHIRP beamwidth 24-16 degrees; ClearVü and SideVü beam patterns at each frequency (e.g., 0.52 x 52 @ 1000 kHz, 0.64 x 35 @ 800 kHz, 1.1 x 52 @ 455 kHz) for high-contrast imaging.
-
Connectivity & Length: 12-pin transducer connectors; 25 ft cable per transducer for flexible routing.
-
Mounting Versatility: Includes hardware for transom, trolling motor, and thru-hull installations; 0°–70° transom angle option when used with the GT56UHD-TM mount.
-
Physical Dimensions: Each transducer measures 218.5 mm × 51.8 mm × 27.7 mm (without mount).
-
What’s in the Box: GT56UHD-TH transducer x 2; stainless steel stems x 2; fairing blocks x 2; isolation plates and bushings x 2; Y-Cable; mounting hardware; documentation.
With the GT56UHD-THP, you gain deep, color-rich imaging that helps you spot fish, structure, and habitat at a glance. The dual-transducer design delivers comprehensive coverage from multiple angles, while flexible mounting options keep your boat setup clean and adaptable. Each transducer features a 25 ft cable to make routing through your vessel straightforward, so you can focus on the catch rather than the setup.
