  • Airmar TM185C-HW High Frequency Wide Beam CHIRP Transom Mount 14-Pin Transducer f/Humminbird [TM185C-HW-14HB]

    TM185C-HW High Frequency Wide Beam CHIRP Transom Mount 14-Pin Transducer for Humminbird

    Get more coverage under the boat with Airmar's wide beam Chirp. Offering a high frequency range of 150-250 kHz and a constant 25° Beamwidth, this transducer is truly broadband at its best. In addition to improving the performance of Chirp-ready echosounders, anglers using this wide beam transducer will achieve twice the coverage under the boat compared to our current high frequency Chirp transducers.

    A unique property of the high frequency transducers is that the Beamwidth is a constant 25° 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 wide beam format also creates crisper and larger return images on the display.
