This thru-hull transducer provides ultra-clear sonar pictures of objects, structure and fish that pass below your boat. This traditional sonar and CHIRP DownVü/SideVü transducer is optimized for depth performance and rough conditions.
The CHIRP DownVü/ SideVü elements have a power rating of 500 W per element (1,500 W total) and operating frequencies of 260/455 kHz. The traditional sonar has a power rating of 600 W and operating frequencies of 50/200 kHz. It includes a built-in fast-response temperature sensor. For hull deadrises less than 5 degrees.
GT41-TH includes a 12-pin transducer with stainless steel stem, fairing block, isolation plate and bushings, mounting hardware and installation instructions. Follow the instructions carefully to avoid damaging your boat.
