SCUBA diving equipment is composed of a heavy SCUBA pressure vessel, buoyancy compensation device and a heavy weight system. Together with a constricting exposure suit the current setup makes for a rather cumbersome system. Perfect buoyancy is a term used in SCUBA diving to describe the ability of the diver to maintain its vertical position in the water column. Doing so requires a thorough understanding of the governing physics principles as well as considerable practice time. Together, the cumbersome nature of standard SCUBA systems and the physical and mental requirements of operating said systems underwater are a commercial hurdle, preventing many individuals from entering the sport. The present invention provides systems that can significantly simplify both elements by allowing water to occupy some of the pressure vessel internal volume. Such a pressure vessel can be used as both the breathing gas source as well as a buoyancy control device, reducing or even eliminating the need for additional weights and a separate buoyancy compensation device. Embodiments of the present invention also comprise a control system and one or more sensors to provide an automatic buoyancy system.

Disclosed is a ballast for a underwater diving belt, the ballast including a metal core covered with a coating, and a unit for the assembly thereof to a belt strip. The coating is in the form of an add-on shell consisting of at least one shell part made of a plastic material and held around the metal core by a fastener.

A buoyancy control device having a back panel and including at least one flotation bladder, which at least one flotation bladder is configured with the device for controllable inflation and deflation, and connected thereto a harness arrangement for securing the device to a body of a user, the device having a cylinder-mounting mechanism arranged to enable front or side mounting of at least one breathable gas cylinder is useful for snorkeling and diving or repeated diving from snorkeling. A particularly preferred configuration provides a lightweight device of less than 5 kg and an apparatus of no more than 10 kg whereby carriage to and from snorkeling and/or diving location is simplified.

A back pack cinch for a strap securing a breathing tank, and an associated buoyancy compensation device worn by a driver are provided. The back pack cinch includes a cinch body. A cover is rotatably mounted to the cinch body. The cover has an open position and a closed position. The cover in the closed position is configured to tension a strap. A tab is rotatably mounted to the cinch body. The tab has an open position and a closed position. In the closed position, a portion of the strap is pressed against the serrated bearing surface by the tab to hold the portion of the strap in a fixed position.
