A thru-hull CHIRP transducer perfectly suited for smaller fishing boats. The B765LH provides the performance of the larger transducers but in a compact package for smaller boats. A great combination of low and high frequency bands provides a wide range of depth capability and fish finding. The low frequency band provide excellent depth penetration while the high frequency excels at shallow water performance, bottom detail and target resolution. The included high performance fairing improves broadband performance at speeds over 30 knots (34 mph). The B765LH transmits across the following bandwidths – low frequency 40 to 75 kHz, high frequency 130 to 210 kHz.
