A physical fitness system incorporating aspects of scuba diving and hyperbaric pressure therapy is described. An enclosure, such as a cage or elevator, is selectively placed in a body of water, such as an ocean, lake, river, or pool, wherein one or more individuals can remain or exercise (e.g., scuba dive) there, for a sufficient period of time and for a sufficient number of times in order to realize a health benefit, such as reduced weight, reduced blood pressure, increased metabolic rate, increased energy levels, and / or the like. Additionally, hyperbaric pressure therapy can also be employed in conjunction with the use of the enclosure. For example, the enclosure, such as a swimming pool, can be situated in a selectively sealable structure. The structure is first sealed and then the pressure inside the structure is raised to a sufficient level to produce a hyperbaric pressure state therein. The individuals in the water-filled enclosure would then remain or exercise there for a sufficient period of time and for a sufficient number of times to realize a health benefit. An oxygen-rich air environment can also be provided in the sealed structure, as well.

A device is provided for releasing a spear shaft of a spear gun for scuba diving or the like. The shaft has a latch element formed on a first lever pivotally connected at its front end to a screw attached to and integrally with a frame of the gun, the lever being maintained elastically in a resting position. The gun has a trigger with an abutment portion forced elastically against the front end of the first lever extending forward of a convex upper surface. The convex upper surface intersects a concave surface at an edge that traces a first circular trajectory when the trigger is rotated. A second lever is rotatably connected to the frame, the front end of the second lever being movable along a second circular trajectory intersecting the first circular trajectory. An arm of the second lever extends so as to intersect the trajectory of the spear shaft when it is loaded in the gun, such that the shaft abuts the latch element first, thereby moving the first lever away from its resting position, until it engages a shaped cavity of the shaft, and subsequently abuts the arm of the second lever. This causes the second lever to turn until it abuts the first lever in line with the latch element, simultaneously raising its front end up to and against the convex surface of the trigger. The front end of the first lever is slidingly connected to a screw, such that the first lever may be variably displaced, thereby adjusting the force applied by the second lever to the trigger.

A device used in beach-entry scuba dives that both assists the diver to transport scuba tanks and other diving gear to and across the shoreline, and then accompanies the diver and gear underwater. The device holds at least one scuba tank and associated gear such as a buoyancy compensator (BCD), and has a pair of wheels whose rolling position enables the loaded device to be easily transported over natural terrains. Upon reaching or while in the water the wheels may be shifted from the “rolling position” into a streamlined, free-swim position. The means attaching the scuba gear and the scuba tank are easily operated to let the user now don both scuba tank and gear and start their dive, taking the device along for the return cross-shore trip.
