Gas blending for scuba diving (or gas mixing) is the filling of diving cylinders with non-air breathing gases such as nitrox, trimix and heliox. Use of these gases is generally intended to improve overall safety of the planned dive, by reducing the risk of decompression sickness and/or nitrogen narcosis, and may improve ease of breathing.
A lifting bag is an item of diving equipment consisting of a robust and air-tight bag with straps, which is used to lift heavy objects underwater by means of the bag's buoyancy. The heavy object can either be moved horizontally underwater by the diver or sent unaccompanied to the surface. [1] Lift bag appropriate capacity should match the task ...

Body-shaped training aids such as the modern "body opponent bag" are made primarily of synthetic materials, and punching bags are sometimes mounted on a weighted pedestal rather than hanging from ...
Lowering the oxygen content of a breathing gas mixture increases the maximum operating depth and duration of the dive before which oxygen toxicity becomes a limiting factor. Most trimix divers limit their working oxygen partial pressure [PO 2 ] to 1.4 bar and may reduce the P O 2 further to 1.3 bar or 1.2 bar depending on the depth, the ...
