TM-275LHW Transom Transducer


Get more coverage under your boat with Airmar’s unique wide-beam, low and high-frequency, Chirp-ready TM275LHW. The high band operates across a frequency range of 150 to 250 kHz and has a fixed 25° 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 are essential down to 152 m (500′). 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 transducer with wide-beam coverage.
