Looking for a thru-hull transducer that will provide both CHIRP/ClearVu and traditional sonar with temperature, to your compatible Garmin Fishfinder then the GT21-TH should be considered because it will provide 500 watts of power for CHIRP/ClearVu using frequencies 260/455 and 600 watts of conventional penetrating power through operating frequencies of 50/200 KHz. The GT21-TH can be used on boats with a deadrise up to 25 degrees, and comes complete with fairing block, isolation plate, bushings, and mounting hardware. If you have aluminum or other metal boat the GT21-TH is constructed of stainless steel so you do not have to worry about corrosion between the hull and the transducer.
