Description
R509C-LM CHIRP 3KW Transducer
Unlock the true potential of your fish-finder with the superior quality and performance of an AIRMAR Chirp-ready transducer.
Features:
- Depth & fast-response water-temperature sensor
- Epoxy transducer housing with high-performance fairing
- For use on hulls up to 25° deadrise
- 82 kHz of total bandwidth from one transducer
Benefits of Thru-Hull Transducers with High-Performance Fairing:
- The best performance on vessels 25 feet and up because the transducer face is in “clean” water below the boundary layer (bubbles running down the hull)
- The fairing compensates for hull deadrise and reduces turbulence over the transducer face, which allows tracking at speeds over 30 knots (35 MPH)
- When mounted in clean water (forward of propellers and running gear), thru-hulls produce the most effective signal return since nothing on the vessel interferes with the transducer’s active surface
