An interactive dive apparatus for use by a scuba diver to determine a maximum dive duration, including an input interface for inputting dive specific parameters including a J-factor for adjusting a no-stop time calculation to compensate for various environmental and physiological parameters, a clock for determining an elapsed dive time, and a depth sensor for detecting a present depth and a maximum depth. The depth sensor tracks diver dwell time in each of plural predetermined depth ranges, and a CPU determines a no-stop time in accordance with the user inputted dive specific parameters and the detected dwell time. The interactive dive apparatus further includes a display screen for displaying at least the no-stop time, elapsed dive time duration and the current depth.

A torso-conforming diver's weight pouch for use by a diver in a buoyancy compensator vest containing at least one recess. At least one weight for neutralizing the diver's buoyancy is contained within a pocket on the pouch. Attached to the pouch is a curvature retaining device which defines and retains a curved configuration of the pouch. The diver can manipulate the curvature retaining device to determine the pouch's configuration. Such configuration can be changed to conform to the diver's hips. Therefore, when the pouch is installed into a buoyancy jacket, the pouch provides more comfort to the diver.

A diver's buoyancy compensator employs a constant volume chamber which is controllably pressurized with air from the diver's SCUBA tank, and water is admitted to or emitted from the tank by one or the other of two manually operated valves.

A capillary depth gauge employs a transparent cover member having an annular magnifying lens portion overlying the capillary passageway to facilitate reading of the gauge.

A filter formed of minute fibers of borosilicate glass is mounted to the inlet-outlet valve of a rechargeable pressure vessel to remove entrained particles from fluid entering and exiting the vessel.
