Abstract: A diving harness containing the upper junction connected through the central rail and shoulder straps to the lower junction connected with the hip belt and the crotch strap tied with the buckle, characterized in that the upper junction is permanently connected to the central rail containing at least two layers of textile tapes that are in contact with each other, wherein the textile tape layers are sewn together at regular intervals with back tacks forming through openings between tape layers, wherein the lower junction is permanently connected to at least one mounting bracket, and, wherein the mounting bracket is detachable connected to the central rail via the through opening.

Abstract: A first-stage diving regulator including the profiled body, swivel turret and the cylinder connector, whereas the axis of rotation of the swivel turret is perpendicular to the body axis, thus enabling by preferable arrangement of low pressure LP ports and high pressure HP ports of the body, and preferable arrangement of low pressure LP ports in the swivel turret and proper hose configuration at any possible equipment configuration by using the same first-stage regulator.

Abstract: A second stage diving regulator with separated stages that allows changing a position of connection of a LP hose for low pressure supplied from a first stage of the regulator, characterized in that around connected bodies there is a rotating ring with a valve seat and a valve terminated with a thread to which a low pressure LP coming from the first stage of the machine is connected horizontally. The rotation of the rotary ring is ensured at least in the range of 180 degrees from the starting position, through all the intermediate angles downwards towards the cylinder, up to a horizontal position opposite to the starting position, the side of the body.

Abstract: A first-stage diving regulator comprising the profiled body, swivel turret and the cylinder connector, whereas the axis of rotation of the swivel turret is perpendicular to the body axis, thus enabling by preferable arrangement of medium pressure LP ports and high pressure HP ports of the body, and preferable arrangement of medium pressure LP ports in the swivel turret and proper hose configuration at any possible equipment configuration by using the same first-stage regulator.

Abstract: A second stage diving regulator with separated stages that allows changing a position of connection of a LP hose for low/medium pressure supplied from a first stage of the regulator, characterized in that around connected bodies there is a rotating ring with a valve seat and a valve terminated with a threat to which a low/medium pressure LP coming from the first stage of the machine is connected horizontally. The rotation of the rotary ring is ensured at least in the range of 180 degrees from the starting position, through all the intermediate angles downwards towards the cylinder, up to a horizontal position opposite to the starting position, the side of the body.
