B275 Low-High Wide, 1kW, w/ FB, Navico BL Y-Cable, DT 1 kW Get more coverage under your boat with Airmar s unique wide-beam, low and high-frequency, Chirp-ready B275LHW. The high band operates across a frequency range of 150 to 250 kHz and has a fixed 25 degree beam for all frequencies which results in superior resolution. The constantly wide beam provides twice the coverage and clear fish arches on the display compared to most high-frequency, narrow-beam transducers. The high wide is the ideal choice for both inshore and pelagic fishing, where resolution and maximum coverage under the boat are essential down to 152 m (500 ft). The low-frequency band and 1 kW of power also support great deep-water performance. Get the best of both worlds with Airmar s Chirp-ready transducers with wide-beam coverage. The included High-performance Fairing improves broadband results at speeds over 30 knots (34 MPH).
