The Garmin B175L is a flush-mount bronze thru-hull transducer built on the Airmar B175 platform, designed for fiberglass and wood hulls across a broad range of deadrise angles. Its 12° tilted internal element accommodates hull deadrises from 8° to 15° without a fairing block, and the housing extends less than 1/4" past the hull surface — keeping it safe on trailer rollers and bunks. With 1kW of output and a maximum depth rating of 3,000 feet, this 8-pin unit is available in low, medium, and high frequency versions to match a variety of sonar systems.
