Garmin GT20-TM Transom Mount 8 pin
Pickup available at Mercury Yacht Harbour
Usually ready in 2-4 days
Description
The Garmin GT20-TM is an 8-pin transom or trolling motor transducer that pairs traditional 77/200 kHz sonar with CHIRP ClearVu (DownVu) scanning to show clear fish arches alongside picture-like images of the structure passing beneath the boat. It is optimised for clearer detail in shallower water.
A built-in fast-response temperature sensor reads water temperature, and the 20 ft cable and 0 to 70 degree transom angle range make installation straightforward on most trailered and small craft. Mounting hardware and instructions are supplied.
The GT20-TM connects to compatible Garmin STRIKER, ECHOMAP CHIRP and GPSMAP combos; an adapter cable may be needed for 4-pin or 12-pin sounder ports.
