Expert Overview

The Airmar B275C-LHW CHIRP Thru-Hull transducer is designed for marine vessels 8 meters (25 feet) and above, particularly those with fiberglass or wood hulls and a deadrise of up to 20 degrees when using a fairing block. This unit provides depth and water-temperature sensing, utilizing wide beam CHIRP technology for enhanced sonar coverage. It operates across two frequency ranges: a low frequency CHIRP from 42 kHz to 65 kHz with a 25� to 16� beamwidth, and a high frequency CHIRP from 150 kHz to 250 kHz with a constant 25� beamwidth. The B275C-LHW-11R is optimized for 50 kHz and 200 kHz frequencies, offering a 123 kHz bandwidth for versatile performance. This transducer aims to provide consistent bottom coverage and fish detection in varying water depths, delivering clearer sonar returns for marine navigation and fishing applications.

Technical Specifications

  • Wide beam CHIRP technology for superior coverage
  • Constant beamwidth across frequency ranges
