This transom-mounted echo sounder gives you highly accurate sonar images of objects, structures and fish under the boat. Combining a traditional sonar with the CHIRP DownVü element, this echo sounder is optimised for performance in deep water and harsh conditions.
The CHIRP DownVü element has a rated power of 500 W and operating frequencies of 260/455 kHz. The conventional probe has a rated power of 600 W and an operating frequency of 50/200 kHz. It also includes a high-speed temperature probe.
GT21-TM includes an 8-pin echo probe, mounting hardware and installation instructions. Follow the instructions carefully to avoid damage to your boat.
