The Garmin GT51M-THP is a pair of GT51M-TH transducers with an interconnect cable.

Each GT51M-TH is a thru-hull combined DownVü and SideVü CHIRP transducer with a 500W power rating. They operate in the 260 kHz and 455 kHz bands.

These models also act as a standard CHIRP transducer in the Medium band (80-160kHz).

A fairing is supplied and this can be cut to match the hull contours and deadrise to ensure the beam faces downwards. One unit is installed each side of the centerline.
