Get more coverage under your boat with Airmar’s unique wide beam, high frequency CHIRP-ready transducers. The high band operates across a frequency range of 150 to 250 kHz and has a fixed 25 deg beam for all frequencies. The high frequency band results in superior resolution. The constant wide beam width provides twice the coverage under the boat and excellent fish arches on the display compared to most high frequency narrow beam transducer options. 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 500 ft. The low frequency band and 2 kW of power also provides great deeper water performance. Get the best of both worlds with Airmar’s dual frequency CHIRP-ready transducers with wide beam coverage.
