Raymarine A80322 B275LH-W Wide Beam Bronze THRU-HULL

The Raymarine A80322 B275LH-W Wide Beam Bronze THRU-HULL transducer is purpose-built for anglers and boaters who demand accurate, reliable sonar performance in both freshwater and saltwater environments. This through-hull mounted unit delivers the real-time bottom structure, fish location, and water column data that separate consistent catches from frustrating blank days on the water. Whether you're targeting largemouth bass in shallow lakes, walleye in mid-depth reservoirs, or offshore species, this Raymarine transducer integrates seamlessly with compatible chartplotters and fishfinders to give you the tactical edge.

Built from marine-grade bronze construction, the B275LH-W features a wide-beam sonar pattern that excels at covering expansive areas and detecting targets across a broader swath of water column. The wide-beam design trades the narrow, hyper-focused cone of traditional narrow-beam units for superior coverage and target density at moderate depths—ideal for structure scanning and school location. The through-hull installation ensures optimal acoustic coupling to the water, eliminating the signal loss and dead zones common with transom or trolling motor mounts. At 24.3 pounds, this transducer carries substantial build quality and is engineered to withstand years of saltwater exposure and mechanical stress from boat movement and wake impact.

This transducer benefits anglers running Raymarine fish-finder and navigation systems, particularly those with larger center consoles, cabin cruisers, or serious fishing platforms where through-hull transducer mounting is feasible. Installation requires proper hull penetration and vacuum-sealed backing, so professional mounting is recommended to avoid water intrusion and maintain warranty coverage. Compatibility with Raymarine's A-series and compatible legacy systems ensures your sonar data feeds directly into your primary navigation display, unifying boat systems and maximizing fishing efficiency. The bronze housing resists corrosion in harsh marine environments, making this a long-term investment for serious anglers who fish year-round.
