3kw Wide-Beam CHIRP

Get more coverage under your boat with Airmar’s unique wide-beam, high-frequency, Chirp-ready transducer. The high band operates across a frequency range of 150 to 250 kHz and has a fixed 25° beam for all frequencies. The high-frequency band results in superior resolution. The constantly wide beam provides twice the coverage and excellent fish arches on the display compared to most high-frequency, narrow-beam transducer options.

High-wide is the ideal choice for both inshore and pelagic fishing, where resolution and maximum coverage are essential down to 152 m (500').

The low-frequency band is rated to 3 kW and delivers amazing deep-water performance to 3,048 m (10,000'). Get the best of both worlds with Airmar’s dual-frequency, Chirp-ready transducer with wide-beam coverage.
