The Oval control combines a microprocessor based trim tab control with an LED tab position indicator. This control incorporates automatic tab retraction and calibration whenever the control power is switched on or off. This unique design requires no feedback sensor for tab position. LED indicators automatically dim at night and brighten in sunlight. The Oval is completely sealed and waterproof. Its rubberized cover is UV protected and will not deteriorate in sunlight. The control switch is self-contained and does not require an additional control box. Lectrotab's Oval control can be used as a single station or can handle up to 6 stations in constant communication with each other.
