ABSTRACT:
A backpack is disclosed for use with scuba gear wherein the backpack includes a rigid housing substantially enclosing an air tank, an interior chamber vented to the surrounding water and formed by the rigid housing for receiving an inflatable buoyancy compensator and a mounting for receiving and securing an adjustable amount of retrievable ballast. The rigid backpack provides a particularly streamlined configuration for the scuba gear, greater puncture resistance for the buoyancy compensator and greater variation in the amount of ballast carried by the diver. The backpack is preferably configured to better support the weight of the scuba gear upon the diver with a trim bladder separately inflatable by the diver and arranged between the backpack and the diver for allowing the diver to adjust for variations in slack, particularly at different diving depths. A power inflator device for the scuba gear preferably includes a single control device for sequentially and adjustably pressurizing a buoyancy compensator, a life vest and/or an inflatable device or transport raft attached to the air tank, a separate control device being provided for permitting the diver to pressurize the trim bladder independently of the buoyancy compensator. An emergency marking device also forms a portion of the scuba gear of the invention.
