Raymarine B765 Through Hull Transducer

Bronze, 300W (L) / 600W (H), for Axiom Pro series and CHIRP sonar modules

B765 Overview
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 W low-frequency ceramic and either a 600 W 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 beamwidth (15°-9°) 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 (34 MPH).
The B765 is fitted with an 11-pin CHIRP transducer connector that mates directly to Axiom Pro RVX, Axiom 2 Pro RVM,  RVX-1000, RVM-1600, CP470, CP570 and legacy CHIRP sonar modules.
