Garmin B75H Bronze 20° Thru-Hull Transducer - 600W, 8-Pin

The Garmin B75H Bronze 20° Thru-Hull Transducer is the professional-grade sonar solution serious anglers and boaters rely on to read structure, locate fish, and navigate confidently in any condition. Built as a thru-hull installation, this 600-watt transducer delivers high-resolution imaging through the hull without sacrificing boat aesthetics or compromising performance.

Whether you're working deep offshore channels, shallow coastal flats, or freshwater lakes, the B75H's bronze construction and proven Garmin engineering provide years of dependable bottom mapping and fish-finding capability. The 20-degree cone angle strikes the ideal balance between wide coverage and tight target definition—wide enough to sweep a meaningful search corridor, narrow enough to pinpoint structure with precision on your chartplotter.

At 600 watts of output power, this transducer cuts through thermoclines, weed, and suspended silt that defeat weaker units, delivering clean returns even in challenging water clarity. The bronze metallic housing resists corrosion in salt and brackish environments while the 8-pin connector integrates seamlessly with Garmin's full ecosystem of marine electronics, ensuring compatibility with legacy and modern systems alike.
