The Garmin B175L Bronze Thru-Hull Transducer is built on the proven Airmar B175L platform and designed for clean, flush installation through fiberglass or wood hulls. Its low-profile housing protrudes less than 1/4" beyond the hull surface, so it rides safely on trailer rollers and bunks without risk of contact damage. An internally tilted element handles a broad range of hull deadrises without a fairing block, keeping the installation straightforward and the hull bottom smooth.
