What is Open Water?

In underwater diving, open water is unrestricted water - a sea, lake or flooded quarries. It is the opposite of confined water (swimming pool) where divers are trained. Open water also means the diver has direct access to the surface of the water in contact with the Earth's atmosphere. Scuba open water implies that if a problem arises, the diver can directly ascend to the atmosphere to breathe air. 

Divers progress from learning diving skills in "confined water" to practicing skills in "open water",   with conditions typical of a natural body of water which might be used by divers.

Some diver certification agencies use a variation on this term in the title of their entry level certification. Open Water Diver certification implies that the diver is competent to dive in open water, with various constraints regarding the conditions.

What is Open Water Diver?

Open Water Diver is an entry-level diver certification for scuba diving. Different agencies use different names but similar entry-level courses are offered by all diving agencies and consist of a combination of knowledge development, practical training and open water dives suitable to allow the diver to dive on open circuit scuba, in open water to a limited depth.
