Garmin GT40-TM Transom Mount Transducer 12pin
Pickup available at Mercury Yacht Harbour
Usually ready in 2-4 days
Description
The Garmin GT40-TM is a 12-pin transom transducer that brings traditional sonar together with CHIRP ClearVu (DownVu) and CHIRP SideVu scanning in a single all-in-one housing. It is optimised for clearer images at shallower depths, showing fish, structure and the bottom directly beneath and to each side of the boat.
A built-in fast-response temperature sensor is included, and the 30 ft cable with a 0 to 70 degree transom angle range suits a wide range of installations. Mounting hardware and instructions are supplied.
The GT40-TM connects to compatible Garmin sonar combos and scanning sonar modules that accept a 12-pin all-in-one transducer, such as ECHOMAP CHIRP sv and GPSMAP xsv combos and the GCV 10 scanning sonar module.
