Overview
2 kW Airmar’s R111LH is an in-hull, 2 kW transducer which delivers excellent target detail, bottom discrimination, and bait and game-fish separation.
The R111LH is packed with a fifteen-element, low-frequency array that operates anywhere between 38 and 75 kHz, delivering great depth capability down to 1829 m (6000′).
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 (1500′). The transducer is installed in the included tank which is cut to the boat’s deadrise angle and affixed inside the hull.
When the transducer is placed inside the tank, it is properly oriented for optimal performance. The R111LH is a popular choice for customers not wanting to drill a hole in their hull and for trailered or multi-hull boats.
