A buoyancy control jacket (1) for scuba diving that includes at least one air chamber (2) with a variable volume delimited by an outer wall (2a) and an inner wall (2b), an abdominal closing strap, and a removable association device between the inner wall (2b) and the abdominal strap, the removable association device including first and second connectors respectively attached to the inner wall (2b) and to the strap, a retainer that retains the second connector relative to the first connector along an axis that is substantially orthogonal to the strap, and a means of rotation about said axis of the second connector relative to the first connector.

Disclosed is a drysuit and/or semi-drysuit hydration assembly including an adapter configured to mate with an inflation valve assembly; a fluid reservoir adapted for positioning internally within a drysuit and/or semi-drysuit; a flexible hose fixedly attached to and passed through a wall of the adapter, the flexible hose having mouthpiece positioned on one end and an opposite end connected to an outlet of the fluid reservoir and being configured to pass fluid from the fluid reservoir to the mouthpiece. Further disclosed is a drysuit and/or semi-drysuit equipped with the hydration assembly.

A mountable Multiple Port Distribution Manifold consisting of a selector knob through which a gas of liquid media may internally flow, between a hollow port at one end and a side port of the rotatable Shaft within the Manifold. By rotating the Knob/Shaft, the side hole port of the Knob/Shaft assembly may selectively intersect with multiple ports within the Manifold. Said assembly also provides of an off position, where no Shaft/Manifold intersection allows port to port connection. The invention may be constructed of any suitable material, natural or synthetic, that is sufficiently strong to withstand the internal pressures of a gas or liquid media routed within without leakage.

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.

The device (50) includes at least one electronic circuit (52) and a battery (53) provided for powering the circuit, wherein the circuit and the battery are included in a block of hydrophobic material, for example a block of resin (51). The battery is, for example, an inductively charged battery and the device can include optical sockets (56a, 56b, 56c) for fiber-optic cables, so as to avoid all contact of metal parts with water. Such a device is especially suitable for a buoyancy compensator vest, for use as a stabilizer during immersion and as a closed-circuit rebreather.
