The Garmin B75M is a broadband bronze thru-hull transducer built with a tilted internal element that self-adjusts to varying hull deadrises — no fairing block needed. It reads depth and water temperature simultaneously, and when paired with a compatible sonar module such as the GSD 26, it supports both Traditional and Spread Spectrum scanning modes. Data travels over the Garmin Marine Network through an 8-pin connector, making it a straightforward upgrade for boats with hulls in the 0–7° deadrise range.
