Offering a high frequency range of 150-250 kHz and a constant 25deg Beamwidth, these transducers are truly broadband at its 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 transducersA unique property of the new high frequency transducers is that the Beamwidth is a constant 25deg angle across the entire frequency band. Now, in addition to providing vast bottom coverage and precise fish detection in the upper water column that can sometimes go unseen with our narrow beam transducers, Airmar's new wide beam format also creates crisper and larger return images on the display.
