The Garmin GT20-TM (part no. 010-01960-00) is a compact plastic transducer for Garmin fishfinders with a 4-pin transducer port and ClearVü support, such as the Striker 4cv and Striker 5cv. It combines dual-frequency traditional sonar with CHIRP ClearVü scanning sonar, so you see both fish arches and a near-photographic picture of the bottom and structure below your boat.
Traditional sonar runs at 77 and 200 kHz with 45° and 15° beams. The wide 77 kHz beam covers more water quickly, while the narrower 200 kHz beam gives better detail on fish and bottom. Maximum traditional depth is 1,900 ft (579 m).
ClearVü uses CHIRP across the 455 kHz and 800 kHz bands to deliver sharp images of what is directly beneath you – rocks, submerged timber, weeds and bottom contours are easy to recognise. ClearVü depth is up to 750 ft (229 m).
A fast-response water temperature sensor is integrated into the cable, displaying temperature on your fishfinder to help you locate productive water.
Hardware for both transom and trolling motor installation is included, and the transducer supports 0–70° deadrise angles. It comes with a 20 ft (6 m) cable and 4-pin connector. Follow the included instructions carefully when installing.
