Entry-level autonomous diver certification for recreational scuba diving
Open Water Diver (OWD) is an entry-level autonomous diver certification for recreational scuba diving. Although different agencies use different names, similar entry-level courses are offered by all recreational diving agencies and consist of a combination of knowledge development (theory), confined water dives (practical training) and open water dives (experience) suitable to allow the diver to dive on open circuit scuba, in open water to a limited depth and in conditions similar to those in which the diver has been trained or later gained appropriate experience, to an acceptable level of safety.
