Automatic Leveling Control

The Automatic Leveling Control (ALC) automatically adjusts roll from side to side and pitch from bow to stern to maintain a level boat and more comfortable and enjoyable ride. The control may also be operated in manual mode. This control incorporates automatic tab retraction and calibration whenever the control power is switched off. This unique design requires no feedback sensor for tab position. LED indicators automatically dim at night and brighten in sunlight. The ALC is completely sealed and waterproof. Its rubberized cover is UV protected and will not deteriorate in sunlight.
