The Airmar B175HW is a bronze thru-hull transducer engineered for serious depth performance without the bulk of a traditional fairing block. Its flush-mounted housing protrudes less than 1/4 inch below the hull, making it safe to rest on trailer rollers or bunks. The internally tilted element self-adjusts to virtually any hull deadrise, and the wide-beam frequency profile gives you sharp, reliable sonar returns at depth.
