Bennett all-in-one AutoTrim Pro 12/24V trim control system composed of LED indicator control panel, control unit with auto tab retractor (ATR) and connection cables. It can be installed on both hydraulic and electric Bolt systems. The control unit detects signals in real time and sends the command to the flaps, correcting the trim in relation to the choice set, the speed, or the sea conditions. The ATR automatically retracts the flaps when the ignition key is removed. Actuator hinge sensors have to be purchased separately for hydraulic systems, they are not required for electrical systems.
