The Airmar R111-LH is a hard-core in-hull CHIRP transducer built for serious anglers who demand precision at depth. Spanning two frequency bands in a single installation, it delivers up to 117 kHz of total bandwidth — resolving individual baitfish, game fish, and underwater structures down to 3,000 m (10,000 ft). Solid fiberglass hulls with a deadrise of 0° to 22° are the ideal match for this urethane-housed unit, and all mounting hardware ships included.
