Lowrance B285H-W High Wide Bronze Thru-Hull 9-Pin

The Lowrance B285H-W High Wide Bronze Thru-Hull 9-Pin transducer is the workhorse choice for serious anglers and boat owners who demand reliable, real-time sonar performance in saltwater and freshwater environments. This bronze thru-hull unit integrates seamlessly with Lowrance fishfinders and chartplotters, delivering the imaging clarity needed to locate structure, baitfish, and bottom composition at depth. Whether you're running offshore or working shallow flats, this transducer provides the foundation for confident navigation and productive fishing.

Built with marine-grade bronze construction, the B285H-W is engineered to withstand corrosive saltwater exposure while maintaining acoustic integrity over years of service. The high-wide beam pattern maximizes coverage area, reducing dead zones and improving target resolution across the water column. The 9-pin connector ensures compatibility with Lowrance legacy and modern systems, offering both traditional 50/200 kHz dual-frequency operation and advanced digital connectivity for systems that support it. Its thru-hull mounting design minimizes turbulence interference, delivering clean, artifact-free sonar returns even at cruising speeds.

This transducer suits anglers upgrading existing Lowrance systems or building new installations on center consoles, cabin cruisers, and larger recreational vessels. Professional guides and tournament anglers favor bronze thru-hulls for their durability and consistent performance in demanding conditions. Installation requires a thru-hull mounting hole and connection to a compatible Lowrance fishfinder unit via the 9-pin cable assembly. Proper installation depth and angle are critical—consult your vessel's hull design and Lowrance documentation to ensure optimal sonar performance and prevent water intrusion.
