Advanced CHIRP Technology for Superior Marine Performance

The Airmar B765C Transducer is designed for serious anglers and marine enthusiasts who require precise depth readings and fast-response water temperature sensing. Equipped with Low and Medium CHIRP capabilities, this transducer offers unmatched clarity and target separation, making it ideal for locating baitfish, game fish, and underwater structures.

Whether you're a commercial fisherman, a charter captain, or an offshore angler, the B765C provides high-resolution imaging with 85 kHz of total bandwidth, covering popular fishing frequencies of 50, 88, and 107 kHz, plus everything in between. Its thru-hull installation ensures optimal performance while maintaining a sleek, hydrodynamic profile.

Precision Depth and Temperature Sensing

This transducer features a depth and fast-response water temperature sensor, allowing for real-time updates and improved situational awareness. Its advanced CHIRP technology enables bottom detection down to 3,000 meters (10,000 feet) with 5 to 10 times greater detail and resolution than traditional sonar.

Wide CHIRP Frequency Range for Enhanced Detection

  • Low CHIRP: Operates from 40 kHz to 75 kHz, providing a 32° to 21° beamwidth for excellent deep-water penetration.
  • Medium CHIRP: Operates from 80 kHz to 130 kHz, with a 24° to 16° beamwidth for enhanced mid-range target detection.
  • Total Bandwidth: Covers a full 85 kHz range, capturing a broad spectrum of sonar data in one installation.
