Garmin B619 12° Bronze Thru Hull Transducer - 8-Pin

The Garmin B619 12° Bronze Thru Hull Transducer with 8-pin connector is a proven fishfinder transducer built around a tilted ceramic element designed to minimize hull drag while delivering reliable sonar performance. The bronze housing requires no fairing and sits nearly flush against the hull—just 5mm of material extends outside—making it ideal for vessels where hydrodynamic efficiency matters. This transducer has been the standard in low-profile installations for years, delivering consistent depth readings down to 206 meters (700 feet) in freshwater and coastal applications.

The B619's 12° beam angle and tilted ceramic element provide built-in deadrise compensation, eliminating the need for external angle adjustments on most hull designs. Large, sensitive ceramic elements generate sufficient acoustic power to cut through thermoclines and suspended sediment, critical for finding structure and baitfish at depth. The 8-pin connector ensures compatibility with most legacy Garmin fishfinder units and older marine electronics systems. At 3.4 lbs, the transducer weighs little enough to avoid stressing through-hull fittings on smaller vessels while delivering the acoustic sensitivity expected from a professional-grade sonar component.

This transducer suits both weekend anglers upgrading existing fishfinder systems and serious offshore operators maintaining equipment on boats already running Garmin legacy electronics. The vertical beam pattern works well for traditional bottom-scanning in open water, while the flush-mount design keeps drag minimal on fishing boats where fuel efficiency and cruising speed matter. Saltwater anglers benefit from bronze construction, which resists corrosion better than aluminum in harsh marine environments. Freshwater bass fishermen and walleye anglers running older Garmin systems will find the B619 a reliable upgrade that preserves compatibility with their existing units.
