Ideal for coastal and offshore anglers, this thru-hull mounted transducer with a stainless steel stem delivers exceptional sonar clarity in all conditions. Designed for those who demand performance, it features CHIRP traditional sonar, CHIRP ClearVü, and CHIRP SideVü scanning sonar - providing crisp fish arches, superior target separation, and detailed images of fish, structures, and objects both below and to the sides of your boat. Optimized for rough sea conditions, the Garmin transducer ensures reliable performance when the water gets choppy.
The CHIRP ClearVü and SideVü elements each offer 500 W of power and operate at 260/455 kHz, while the traditional CHIRP sonar delivers 600 W of power across the mid-band 80–160 kHz range. A built-in fast-response temperature sensor provides accurate readings in real time. Suitable for hull deadrises under 5°.
The GT51M-TH package includes a 12-pin transducer with stainless steel stem, fairing block, isolation plate and bushings, plus mounting hardware and detailed installation instructions. Be sure to follow all steps carefully to ensure a safe and proper fit to your boat.
