Advanced Dual-Band Chirp Transducer for Superior Marine Performance

The Airmar R509C-LHW is a powerful thru-hull transducer designed for both deep-water and shallow-water applications. Engineered with a high wide beam and a low-frequency band, this 3kW transducer delivers unparalleled resolution, extensive coverage, and superior fish-target separation. Whether you're fishing inshore or offshore, the R509C-LHW ensures optimal performance with its Chirp-ready technology, making it a top choice for professional and serious recreational anglers.

Exceptional Deep-Water and Shallow-Water Capabilities

The R509C-LHW is equipped with dual-band frequency operation, allowing it to excel in a wide range of marine environments. The low-frequency band (28-60 kHz) penetrates deep waters up to 3,048 meters (10,000 feet), while the high-frequency band (150-250 kHz) provides superior resolution and coverage in depths up to 152 meters (500 feet). Its consistently wide beamwidth of 25° at high frequency ensures enhanced detection of fish in the upper-water column, making it an excellent choice for various fishing applications.

Wide-Beam Coverage for Increased Detection

Unlike traditional narrow-beam transducers, the Airmar R509C-LHW utilizes a high wide-beam design that provides twice the coverage area. This ensures enhanced target separation and more detailed fish arches, even in the upper-water column. The combination of Chirp technology and broad frequency range enables clear and precise imaging for improved fish-finding efficiency.

Rugged Design for Long-Lasting Marine Use

Built with durable urethane housing and an epoxy/urethane acoustic window, the R509C-LHW is designed to withstand harsh marine conditions. Its robust construction ensures long-lasting performance, making it an excellent investment for serious anglers and marine professionals alike.
