A backpack assembly for a self contained breathing apparatus comprises a plurality of components positioned in housings that define a body for the backpack assembly. The body is assembled to a back frame. A pivoting and swiveling hip plate is connected to the back frame in multiple distinct positions to provide a customizable and comfortable fit for the wearer.

The present invention relates to an all-purpose, pneumatic powered signaling device including a first component capable of transmitting signals above water and a second component capable of transmitting a signal beneath the water. The first component includes a pneumatic air horn and the second component a diaphragm and piston. A button actuator is selectively depressed to create a flow passageway from a source of compressed air to the first and second components. A selector switch is selectively adjustable to allow a stream of compressed air flowing through the passageway to enter either the first or the second component and transmit a signal above or below the water.

The present invention comprises an oil-filled depth gauge which is made far less sensitive to violent shock and the potential resulting inaccuracies to the maximum depth gauge indicator from such shock. More specifically, the present invention comprises an improved oil-filled scuba diving depth gauge in which the improvement provides a fluid dam member which may be affixed to or molded into the transparent enclosure covering the dial face to effectively block the flow of the oil in the region of the gauge occupied by the maximum depth indicator dial. The fluid dam reduces the likelihood that a sudden jar or other violent shock will induce a relative differential in the motion between the oil and the gauge body which might otherwise produce inaccuracies in the position of the maximum depth indicator dial.

Affixed to the back plate on opposite sides of a tank seat are brackets providing loops for detachable connection to hooks. An inelastic fabric web, such as of woven nylon, adjustably threads around a buckle bar on one hook, and returns along the inside of the web for firm attachment by hook and mesh fasteners such as 'VELCRO'. The other end of the web fixedly attaches to a metal loop that cooperates with a high leverage toggle mechanism. The toggle mechanism comprises but two parts, the first being a bar forming a hook detachably coupled to the corresponding back plate bracket, the second being a lever hinged to the bar and providing a recess to receive the loop for over center lock and release of the loop by toggle action.
