Aerial Delivery – WISAD Water Initiated Sensing Aerial Disconnect

 

User maintained and refurbished, designed for use on boats and equipment being air dropped into water, the WISAD releases the cargo parachutes from the load on water entry, even in strong winds, thereby ensuring boats are not pulled over or equipment dragged by the inflated parachutes.
