Garmin Airmar B175H

Bronze Tilted Thru-hull Transducer with Depth & Temperature (20 tilt) This tilted transducer protrudes less than a quarter of an inch outside the hull and can sit on trailer rollers/bunks without damage.

An excellent choice for fiberglass and wood hulls, this 1 kW bare wire, bronze transducer has a maximum depth of 3,000 ft; an operating frequency of 130 to 210 kHz; a beamwidth of 6 to 10 degrees; and mounts on a 16 to 24 degree deadrise angle. The tilted element inside the transducer accommodates all hull deadrises and eliminates the need for a fairing block.

Transducer kit comes with installation instructions. Follow the instructions carefully to avoid damaging your boat.
