Airmar R109LHW Chirp Thru-Hull Transducer - No Connector - R109C-LHW

R109LHW Low High Wide Chirp Thru-Hull Transducer with Fairing Block - No Connector

Get more coverage under the boat with Airmar’s unique wide-beam, low- and high-frequency, Chirp-ready R109LHW. 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 essentially down to 152 m (500'). The low-frequency band and 2 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.


  • Depth and fast-response water-temperature sensing
  • 2 kW of power for excellent deep-water performance from the low-frequency
