The Airmar R409C-LWM is a thru-hull CHIRP transducer built for tournament anglers who need maximum water-column coverage. It operates across two CHIRP bands — a low-frequency 40–60 kHz sweep with a 40° constant beamwidth for broad, deep coverage, and a medium-frequency 80–130 kHz sweep for sharper target definition. The urethane housing and epoxy/urethane acoustic window are designed for fiberglass hulls, and integrated Xducer ID® technology ensures precise communication with compatible displays. A fast-response depth and water-temperature sensor rounds out the feature set.
