The B765LM transducer is a bronze, thru-hull depth and temperature sensor compatible with Raymarine’s CP450C ClearPulse CHIRP sonar. It features a depth and fast-response water temperature sensor in a bronze housing with high-performance fairing.
The B765LM covers the low-frequency spectrum from 40 kHz to 75 kHz with a beam width of 32° to 21°. It also covers the medium-frequency spectrum from 80 kHz to 130 kHz with a beam width of 24° to 16°. The overall bandwidth of this transducer is 85 kHz, and covers the popular fishing frequencies of 50, 88 and 107 kHz plus everything else in the bandwidth. The B765LM is designed to provide all the advantages of the larger thru-hull transducers, in a compact size suitable for smaller boats.
Medium-frequency benefits include the ability to sound deeper than the high-frequency, along with better target resolution than low-frequency transducers offer.
The internal array consists of 2 broadband ceramic assemblies for great sensitivity and performance.
The B765LM is intended for boats 30-feet in length or longer, with fiberglass or wood hulls.
