AIRMAR® 509LHW is a top-tier thru-hull transducer developed for demanding anglers and professional users who want maximum depth, precision, and signal strength. With 2–3 kW power, CHIRP Low (28–60 kHz) for deep water and CHIRP High Wide (150–250 kHz) for detailed fish detection at shallower depths, you get a combination of a narrow, deep-searching low-frequency beam and a wide high-frequency beam, which provides fantastic resolution of fish and structure closer to the surface.
The transducer delivers top-level performance with the ability to detect targets down to approx. 6,000 ft / 1,800 meters, making it ideal for offshore fishing, deep-sea fishing, and boats with advanced sonar systems. It measures both depth and temperature, has a robust plastic thru-hull construction, and fits hulls with 0–25° deadrise.
In short – this transducer is for those who want maximum performance, reliability, and the best image quality under all conditions.
