Garmin B619 20° Tilt Bronze Thru-Hull Transducer - 8-Pin

The Garmin B619 20° Tilt Bronze Thru-Hull Transducer with 8-pin connector is purpose-built for serious anglers and cruising boaters who demand reliable sonar performance in freshwater and saltwater applications. This transducer sits at the heart of your fish-finding system, converting your sonar unit into actionable intelligence about structure, bottom composition, and fish location.

Whether you're targeting largemouth bass in shallow reservoirs or pursuing offshore species, a quality thru-hull installation ensures consistent signal transmission that portable or transom-mounted alternatives simply cannot match. The 20° tilt angle is engineered to optimize sonar cone coverage while minimizing dead zones directly beneath the hull—critical when navigating variable bottom terrain or working tight structure. Bronze construction resists corrosion from saltwater exposure and UV degradation, ensuring years of service without performance drift.

The 8-pin connector design provides secure integration with compatible Garmin chartplotters and sonar units, establishing a permanent, noise-free electrical connection that eliminates the intermittent signal loss common to surface-mount systems. Thru-hull installation requires careful mounting below the waterline, but the resulting acoustic clarity and structural stability reward the effort with superior bottom tracking and fish arch definition. This transducer suits boats with fiberglass hulls where permanent installation is feasible.
