The Airmar B175H thru-hull transducer delivers 1 kW of CHIRP power through a flush-mounted bronze housing that extends less than 1/4 inch below the hull — no fairing block required. The internally tilted element self-compensates for hull deadrise, making it compatible with a wide range of fiberglass and wood hulls. Its low-profile design sits safely on trailer rollers or bunks without risk of damage, and the 130–210 kHz high-frequency CHIRP operation provides sharp target separation down to 1,200 feet.
