Airmar B275LHW Wide-Beam, Chirp-Ready Through-Hull Transducer

Maximize the coverage of the ­waters beneath your fishing boat.

Product Information

What anglers want to see beneath their boats is simple: fish and more fish. The Airmar B275LHW wide-beam, chirp-ready through-hull transducer will help make it happen with a fixed 25-degree beam for all frequencies, providing superior resolution to 500 feet in the high-frequency range of 150 to 250 kHz. The low-frequency band pings through the depths at 42 to 65 kHz at 1 kW of power, boosting depth range clear down to 3,000 feet. In either case, your bottom coverage is doubled over what’s provided by traditional narrow-band non-chirp transducers.



  • Depth and fast-response water-temperature sensor
  • 1 kW for great deep-water performance from the low frequency
  • Low frequency: 42 to 65 kHz
  • High frequency: 150 to 250 kHz
  • 123 kHz of total bandwidth from one transducer
  • Covers popular fishing frequencies of 50 and 200 kHz plus everything else in the bandwidth
  • High frequency delivers superior shallow-water performance, bottom detail, and fish-target separation
  • High wide beamwidth yields more coverage for detecting fish in the upper-water column
  • Bronze housing with high-performance fairing for optimal performance at higher speeds
  • Also available as transom (TM275LHW) and pocket/keel (PM275LHW) mounts
  • Exclusive Xducer ID® technology
