Garmin GT22HW-TM Plastic, TM or Trolling Motor Transducer, High Wide CHIRP/CHIRP DownVü - 455/800kHz, 500W, 8-Pin

Experience precise, dual-mode sonar from Garmin with the GT22HW-TM transducer—a compact, high-performance solution for freshwater anglers mounting to a trolling motor or transom. It delivers both CHIRP traditional sonar and CHIRP DownVü scanning sonar for unmatched target clarity and structure detail beneath your boat.

Engineered for reliability, the GT22HW-TM features an 8-pin design and dual power ratings: CHIRP traditional sonar operates in the 150–240 kHz range with up to 250 W, while CHIRP DownVü uses 455/800 kHz with up to 500 W. This combination translates to crisp fish arches, excellent target separation, and clear definition of underwater structure even in tough conditions.

Its compact size makes it ideal for mounting on a trolling motor, yet its robust construction and included installation guidance help you set up quickly and safely on your boat’s transom or trolling motor.
