It’s a thru-hull, Chirp transducer perfectly suited for smaller fishing boats. The B765LH gives the performance of the larger transducers but in a compact package. A great combination of low and high-frequency bands provides a wide range of depth capability and fish finding. The low-frequency band, operating from 40 to 75 kHz, gives excellent depth penetration. Meanwhile the high-frequency range of 130 to 210 kHz excels in shallow water for bottom detail and target resolution.

The included High-performance Fairing improves broadband performance at speeds over 30 knots (34 MPH).

This transducer is available in two options: one with an OEM connector designed specifically for your fishfinder, and another as a Mix and Match™ Transducer version. The Mix and Match™ transducer has a 9-meter (29.5’) cable with a standard connector, plus a 1-meter (3’) adapter cable to connect it to your fishfinder.

Weight: 2.5 kg (5.5 lb)
Hull deadrise compatibility: Up to 24° with fairing

Recommended boat length: Up to 9 m (30') and above
