2 kW
The R109LH is an externally mounted, 2 kW transducer which delivers excellent target resolution, bottom discrimination, and bait and game-fish separation. The R109LH is packed with a fifteen-element, low-frequency array that operates at anywhere between 38 and 75 kHz, delivering great depth capability down to 1,829 m (6,000').
The single, high-frequency ceramic operates at any frequency between 130 and 210 kHz and has a narrow (8° to 4°) beam that provide tremendous bottom detail and fish-target discrimination at depths to 457 m (1,500').
