Garmin GT51M-THP pair of 12-pin thru-hull transducers with CHIRP, ClearVü and SideVü. Availability and terms on request.

The Garmin GT51M-THP is a pair of 12-pin thru-hull transducers for mid-band CHIRP traditional sonar, ClearVü and SideVü. Paired installation requires hull geometry and location planning.

What should be assessed for thru-hull installation?

Hull material, geometry, internal space and position relative to the engines are part of the assessment. Share your vessel and sonar models to review components and mounting. Installation requires planning for the hull and verification of the assembly, without assuming universal vessel compatibility.
