The Airmar B175H thru-hull transducer pairs 1 kW of CHIRP power with a low-profile bronze housing that protrudes less than 1/4 inch below the hull — no fairing block needed. A 12-degree internally tilted element self-compensates for hull deadrise, so installation is straightforward on fiberglass and wood hulls across a wide range of deadrise angles. The slim profile clears trailer rollers and bunks without issue, while 130–210 kHz CHIRP High operation delivers crisp target separation to 1,200 feet. An integrated temperature sensor and 8-pin connector round out the package.
