SSI allows OWD divers to dive to a maximum depth of 18 meters ...
PADI allows SD divers to dive to a depth of 12 meters, accompanied by a PADI Divemaster or Instructor. The PADI Scuba Diver course includes the first three lessons of the five-part Open Water Diver course (OWD).

[3] The then President of the University of California, Robert Gordon Sproul, restricted diving to those who had been trained through the program at SIO and thus "certification" was born.
In underwater diving, open water is unrestricted water such as a sea, lake, river, or flooded quarry.It is a contradistinction to an overhead environment, where there is a physical barrier to direct vertical ascent to the surface, and to a flooded confined space where there may not be enough room to maneuver freely.
