Airmar B765C Low High CHIRP With Garmin 12-Pin MMC

The Airmar B765C Low High CHIRP with Garmin 12-Pin MMC is a professional-grade dual-frequency transducer purpose-built for anglers and boaters who demand clarity in both shallow and deep water. This transducer combines low and high CHIRP frequencies into a single housing, eliminating the need for separate units while maintaining the precision that serious fishermen require. Whether you're working shallow flats or running deep offshore, this transducer delivers real-time bottom structure and fish detection on compatible Garmin chartplotters.

The B765C-LH-12G operates across two distinct frequency bands: the low CHIRP mode sweeps from 40 kHz to 75 kHz with a 32° to 21° beamwidth for deep-water penetration and wider coverage, while the high CHIRP mode ranges from 130 kHz to 210 kHz for superior target separation and fine detail in shallow zones. This dual-frequency architecture allows you to adapt your sonar presentation to water depth and conditions without switching equipment. The integrated fast-response water-temperature sensor provides real-time thermal data critical for locating thermoclines and seasonal fish movement patterns. The Garmin 12-pin Mix-N-Match cable ensures direct compatibility with standard Garmin marine electronics, simplifying installation on existing systems.

This transducer is ideal for dedicated anglers operating 20-foot to 60-foot vessels equipped with Garmin chartplotters, particularly those running freshwater lakes, coastal bays, and offshore environments where water-column scanning and bottom mapping are essential. The compact 5-pound design makes it suitable for transom or thru-hull mounting on center consoles, offshore rigs, and larger recreational boats. Installation requires a Garmin-compatible display with dual-frequency CHIRP support; verify your chartplotter's specifications before purchase to ensure seamless integration and full functionality of both frequency bands.
