Garmin Airmar B175M Navigator transducer

Step up to 1 kW without a fairing with this flush-mounted bronze housing that protrudes less than 1/4-inch outside the hull and can sit on the trailer rollers/bunks without damage.
The tilted element inside the transducer accommodates all hull deadrises and eliminates the need for a fairing block. And, low, medium and high frequency versions provide maximum flexibility for the choice of frequencies.
An excellent choice for fiberglass and wood hulls, this 8-pin transducer has a depth of 1,700 ft; an operating frequency of 85-135 kHz; a beamwidth of 11-16 degrees; and a 16 to 24 degree deadrise.
Transducer kit comes with installation instructions. Follow the instructions carefully to avoid damaging your boat.
