The Airmar PM111LH installs flush within a custom pocket in your hull or keel, making it a go-to choice for boat builders and retrofit applications where a suitable pocket already exists. It delivers dual-channel Low-High CHIRP sonar at 2kW alongside a fast-response water-temperature sensor, covering everything from shallow bottom structure to deep offshore targets — all without requiring a high-performance fairing block. Compatible with fiberglass and metal hulls of stepped, planing, or displacement designs, and works with any deadrise angle or propulsion type.
