Lowrance B285M Medium CHIRP Bronze Thru-Hull 9-Pin

The Lowrance B285M Medium CHIRP Bronze Thru-Hull 9-Pin transducer is designed for serious anglers and boaters who require dependable sonar performance in both freshwater and saltwater environments. This bronze transducer mounts permanently through your boat's hull, providing consistent target identification and bottom mapping from the moment you leave the dock. Whether you're fishing in a lake or trolling coastal shallows, the B285M combines affordability with professional-grade sonar technology.

The B285M utilizes CHIRP (Compressed High-Intensity Radar Pulse) technology, which transmits a continuous sweep of frequencies to improve target separation and reduce noise interference in congested water columns. Its medium-frequency design offers a practical balance between depth penetration and high-resolution detail, making it effective in depths approaching 1,200 feet under optimal conditions. The bronze construction ensures durability and corrosion resistance in saltwater environments.

The Lowrance B285M is ideal for anglers looking to upgrade older systems or retrofit modest center consoles with advanced sonar capabilities. Its 9-pin connector integrates seamlessly with both Lowrance legacy systems and newer models, making it a versatile choice for various boating setups. With this transducer, you can spend less time troubleshooting and more time enjoying your fishing experience.
