KoopNautic FAL 125 Fin Stabilizer Control Unit, P/N 601.00.04 is an OEM electronic control component for a KoopNautic hydraulic fin-stabilization system. It receives vessel-motion and system feedback signals, calculates the required fin correction, and commands the hydraulic control valves so the port and starboard fins counteract vessel roll while underway.

We recently acquired a large inventory of items, these items are used, and may have minor cosmetic blemishes from previous storage (See Photos).
