Abstract
A water safety and survival system that provides a multi-chambered personal flotation device and break away counterweight that provides a heads-up righting moment that reliably positions a scuba diver with his/her airway out of the water when at the surface, and provides for a comfortable heads down position during the dive. The scuba diver retains full control and responsibility for conversion of the equipment from face down flotation into face up flotation. The break away counterweight stows the ballast needed to heel the diver into a heads up position in an inactive state, close to the diver's longitudinal axis of rotation. Once released, the counterweight drops away from neutralized central attachment near the diver's axis of rotation out towards the counterweight's posterior attachment point. The counterweight then becomes capable of actively rolling the distressed diver's face out of the water into the heads up position. The counterweight is preferably utilized in conjunction with a buoyancy compensator that further provides for rotation of the diver into a heads up orientation, and that can provide buoyancy compensation for the counterweight.
