The Garmin GT41-THP is a pair of GT41-TH transducers with an interconnect cable.
Each GT41-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 conventional 600W non-CHIRP transducer at 50 kHz and 200 kHz.
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.
