ABSTRACT:
An attitude adjusting apparatus for use by scuba divers automatically varies the position of ballast relative to the center of buoyancy as the attitude of their body underwater changes. An elongate hollow weight tube enclosed at one end has a removable closure at the opposite end and contains a quantity of small metal balls or shot. The weight tube is carried in close proximity to the torso of the diver in a position with its longitudinal axis generally parallel to the longitudinal axis of the torso of the diver. The free-moving balls or shot are movably disposed within the interior of the weight tube and are movably distributed at varying locations within the weight tube between a forward lowermost position as the diver assumes a descending head-down position and a rearward lowermost position as the diver assumes an ascending head-up position, and will be distributed along the length of the weight tube as the diver assumes a horizontal position. One or more weight tubes are releasably connected to a diver's air tank or back board by a quick release snap-fit coupling having a resilient jettisoning mechanism which allows the weight tubes to be quickly disconnected and forcefully propelled away from the diver in the event of an emergency. The weight tubes may also be releasably carried in pockets on a buoyancy compensator vest worn by the diver.
