The Airmar B765C-LM is a bronze thru-hull CHIRP transducer built for serious anglers who demand high-resolution bottom and fish imaging. Covering both a low band (40–75 kHz) and a medium band (80–130 kHz), it delivers 85 kHz of total bandwidth from a single installation — capable of bottom detection to 3,000 m (10,000 ft) with up to 10× greater detail than traditional transducers. Sized for vessels up to 9 m (30 ft) and above, it installs in fiberglass or wood hulls with a high-performance fairing included. A Mix & Match cable is required and sold separately; this transducer is not compatible with Simrad or Lowrance systems.
