Garmin GT23M-TM Transom Mount Transducer 8 pin
Pickup available at Mercury Yacht Harbour
Usually ready in 2-4 days
Description
The Garmin GT23M-TM is an 8-pin transom transducer combining Mid Band CHIRP traditional sonar (80-160 kHz) with CHIRP ClearVu (DownVu) scanning. It is tuned for depth performance and rough conditions, giving coastal and offshore anglers crisp fish arches with strong target separation and clear structure detail below 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 supports a wide range of installations. Mounting hardware and instructions are supplied.
The GT23M-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.
