Furuno B275LHW Bronze Thru-Hull CHIRP Transducer - Professional Wide-Beam Marine Sonar with Temperature Sensing
Revolutionary Wide-Beam CHIRP Technology for Superior Underwater Coverage
The Furuno B275LHW Bronze Thru-Hull CHIRP Transducer delivers exceptional underwater performance with over six times the coverage area compared to standard high-frequency CHIRP transducers. This professional-grade bronze transducer combines dual CHIRP frequency ranges (42-65 kHz low, 150-250 kHz high) with innovative wide-beam technology and integrated temperature sensing for comprehensive marine sonar applications.
Advanced Marine Sonar Technology
Wide-Beam CHIRP Excellence
The innovative "W" wide-beam design provides constant 25° beamwidth across the entire high-frequency range (150-250 kHz), delivering over six times the underwater coverage compared to traditional high-frequency transducers. This breakthrough technology ensures comprehensive bottom mapping and fish detection.
Dual-Frequency CHIRP Performance
Operates across two distinct CHIRP ranges: Low-frequency 42-65 kHz for deep water penetration and structure identification, and high-frequency 150-250 kHz for detailed fish detection and bottom definition. Both frequencies maintain optimal beam characteristics for superior sonar performance.
Professional Bronze Construction
Durable bronze housing provides superior corrosion resistance for saltwater applications while maintaining optimal acoustic properties. Engineered for permanent thru-hull installation on fiberglass and wooden hulls with included fairing block for hydrodynamic efficiency.
Integrated Temperature Monitoring
Built-in temperature sensor provides real-time water temperature data essential for fishing success and navigation safety. Temperature information integrates seamlessly with compatible Furuno fish finders and chartplotters.

Wide-Beam Technology Benefits
Superior Bottom Coverage
The revolutionary wide-beam design provides 2X the coverage area compared to standard CHIRP transducers, enabling comprehensive bottom mapping and structure identification. The constant 25° beamwidth maintains consistent performance across the entire high-frequency range.
Enhanced Fish Detection
Wide-beam coverage significantly improves fish detection capabilities by monitoring larger areas under the vessel simultaneously. This technology is particularly valuable for locating schools of fish and identifying individual targets with exceptional clarity.
Improved Navigation Safety
Extended bottom coverage provides better obstacle detection and depth awareness, enhancing navigation safety in shallow or unfamiliar waters. The dual-frequency capability offers both penetration and resolution for comprehensive underwater intelligence.
Professional Thru-Hull Installation
Pre-Installation Planning
Proper installation requires careful hull location selection away from interference sources such as engines, generators, and through-hull fittings. The transducer beam must remain unobstructed by keel or propeller shafts for optimal performance.
Bronze Transducer Advantages
Bronze construction provides excellent corrosion resistance in saltwater environments while maintaining superior acoustic properties. The material compatibility with fiberglass and wooden hulls ensures long-term reliability and performance.
