Upgrade your smaller fishing boat's sonar capabilities with the Raymarine B765LH Bronze Thru-Hull Transducer, a compact powerhouse designed specifically for anglers who demand professional-grade performance without the bulk. This CHIRP-ready sensor pairs seamlessly with Raymarine's CP450C sonar module, delivering crystal-clear images of fish, structure, and bottom contours even at high speeds. Whether you're chasing trophy bass in shallow waters or probing deep offshore reefs, its dual-frequency design ensures you never miss a target.
The B765LH stands out by packing the punch of larger transducers into a hull-friendly size, ideal for boats around 30 feet or more with fiberglass or wood hulls. Its bronze construction withstands harsh marine environments, while the included high-performance fairing lets you maintain broadband sonar clarity at speeds exceeding 30 knots. Anglers love how the low-frequency channel punches through to depths up to 1200 feet for spotting schools in the abyss, and the high-frequency option sharpens focus on individual fish with pinpoint separation.
Engineered for reliability, the B765LH features two high-sensitivity ceramic elements: a 300-watt low-frequency array (40-75 kHz) with a wide 21-23 degree beam for maximum coverage and deep penetration, and a 600-watt high-frequency array (130-210 kHz) narrowing to 9-15 degrees for surgical precision. With a 33-foot cable and support for deadrise angles up to 24 degrees, installation is straightforward for most hull designs. Expect maximum depths of 1200 feet on low and 700 feet on high, making it a go-to for both inland lakes and coastal runs.

To get the most from your B765LH, position it forward of the prop and keel for clean water flow. The fairing block is key—adjust it to match your hull's deadrise for optimal beam projection. Pair it with Raymarine multifunction displays running Lighthouse software for customizable CHIRP sweeps that adapt to your fishing style. Users report fewer false readings around wrecks and better bait ball definition, turning casual outings into limit-filling trips. Its robust build also means less downtime, backed by solid manufacturer support.
B765LH and B765LM are thru-hull, CHIRP-ready transducers that are perfectly suited for smaller fishing boats. Both models deliver the performance of the larger transducers but in a compact package for smaller boats. The B765LH and B765LM each feature a great combination of a 300 Watt low-frequency ceramic and either a 600 Watt high-frequency or medium-frequency band ceramic for a wide range of depth capability and fish finding. The low-frequency band provides excellent depth penetration. The high-frequency band features a narrow beam width (15 Degree to 9 Degree) for excellent target separation. The medium-frequency is perfect for more coverage under the boat and delivering excellent bottom detail. The included high-performance fairing improves broadband performance at speeds over 30 knots.
