Furuno B275LHW-12P Bronze Thru Hull with 12-Pin

The Furuno B275LHW-12P Bronze Thru-Hull CHIRP transducer is designed for larger fiberglass or wooden boats that demand accurate depth and temperature readings with expansive bottom coverage. It supports seamless 12‑pin Furuno integration for reliable performance in saltwater environments.

• 12-Pin Furuno connector: 12-Pin Furuno connector; includes fairing block and mounting hardware for straightforward installation.
• Through-hull bronze construction: Durable bronze housing designed for reliable, long-term saltwater performance.
• CHIRP bandwidth & frequencies: Low CHIRP from 42 kHz to 65 kHz; High CHIRP from 150 kHz to 250 kHz, delivering a total bandwidth of 123 kHz from a single transducer.
• Beamwidth & coverage: High-frequency beamwidth is a constant 25° across the band; low-frequency beamwidth ranges from 25° down to 16°—paired with a wide-beam design that provides substantially more coverage under the boat.
• Depth & temperature sensing: Depth measurement paired with a fast-response water-temperature sensor for real-time condition monitoring.
• Boat compatibility: Suitable for boats 8 m (25 feet) and above; works on fiberglass or wood hulls with a hull deadrise up to 20° using a fairing block for optimal performance.
• Acoustic window: Urethane acoustic window to protect the transducer while maximizing signal transmission.
• What’s in the box: B275CLHW-12P transducer plus fairing block and hardware.

With its wide-band CHIRP design and constant 25° beam across the high-frequency range, you’ll enjoy crisper, larger returns and more bottom detail on your display. The broader coverage reduces blind spots under the hull, enhancing fish-holding areas and structure detection, while the rugged bronze through-hull construction and included mounting hardware simplify installation and provide durable performance in saltwater environments. The combination of deep-water depth readings and real-time temperature sensing helps you make informed decisions on where to fish and how to navigate safely.
