29 results about "Open water" patented technology

In underwater diving, open water is unrestricted water such as a sea, lake or flooded quarries. It is the opposite of confined water (diving) (usually a swimming pool) where diver training takes place. Open water also means the diver has direct vertical access to the surface of the water in contact with the Earth's atmosphere. Open water diving implies that if a problem arises, the diver can directly ascend vertically to the atmosphere to breathe air. Penetration diving—involving entering caves or wrecks, or diving under ice—is therefore not "open water diving". In some contexts the lack of a decompression obligation is considered a necessary condition for classification of a dive as an open water dive, but this does not affect the classification of the venue as open water.
