Airmar B275C-LHW-12G Wide Beam Broadband CHIRP Low/High Frequency Thru-Hull Transducer Garmin 12-Pin

Our BEST just got BETTER!

Get more coverage under the boat with Airmar’s new wide beam CHIRP product line. Offering a high frequency range of 150-250kHz and a constant 25 degree beamwidth, these transducers are truly broadband at it’s best. In addition to improving the performance of CHIRP-ready echosounders, anglers using the new wide beam transducers will achieve twice the coverage under the boat compared to our current high frequency CHIRP transducers.

A unique property of the new high frequency transducers is that the beamwidth is a constant 25 degree angle across the entire frequency band. Traditionally, high frequency transducers have narrow beamwidths that change with frequency. Now, in addition to providing vast bottom coverage and precise fish detection in the upper water column that can sometimes go unseen with current narrow beam transducers, Airmar’s new wide beam format also creates crisper and larger return images on the display.

Improved Beamwidth

Current CHIRP transducers have a narrow beamwidth ranging from 10° to 4° on the high frequency band. The beamwidth of the new wide beam CHIRP transducers is a constant 25° across the entire frequency band—ultimately delivering more than 2x the coverage under the boat than other CHIRP models!
