Garmin GT22HW-TM Transom Mount Transducer

The Garmin GT22HW-TM Transom Mount Transducer is the backbone of any modern fish-finding setup for serious anglers and boaters who demand reliable sonar data in freshwater and saltwater environments. After years on the water, you know that your electronics are only as good as the transducer sending information to your display—and this unit delivers the real-time bottom structure, thermocline, and fish-marking clarity that separates productive days from wasted fuel and hours. Built for anglers who fish everything from shallow creek channels to deep offshore structure, the GT22HW-TM mounts cleanly to your transom without requiring hull modifications, making it an ideal retrofit for existing boats or new builds.

This transom-mount design uses high-frequency sonar technology to generate crisp, detailed returns from the water column and bottom, allowing you to distinguish baitfish schools, thermoclines, and hard cover with confidence. The transducer housing is engineered to minimize turbulence and cavitation even at high speeds, ensuring stable readings whether you're trolling at 2 knots or running 40 mph to the next bite. Weighing just 1.72 lbs, the compact footprint reduces drag and simplifies installation on most transom configurations, while the sealed construction protects internal components from saltwater corrosion and temperature swings that plague cheaper alternatives.

Anglers running Garmin chartplotters and sonar systems benefit from seamless integration—no third-party converters or workarounds needed. Whether you're a bass tournament pro targeting submerged timber, a saltwater guide reading structure on shallow flats, or a recreational boater simply wanting to understand what's beneath your hull, the GT22HW-TM pairs with Garmin's full ecosystem of displays and networking features. Installation requires basic tools and a clean, stable mounting location on your transom; consult your Garmin display manual for specific frequency and cable compatibility to ensure optimal sonar performance.
