Recreational diving or sport diving is a type of diving that uses SCUBA equipment for the purpose of leisure and enjoyment. In some diving circles, the term "recreational diving" is used in contradistinction to "technical diving", a riskier and more demanding application of the sport which requires greater levels of training, experience and equipment.
Recreational scuba diving grew out of related activities such as Snorkeling and underwater hunting. For a long time, recreational underwater excursions were limited by the amount of breath that could be held. However, the invention of the aqualung in 1943 by Jacques-Yves Cousteau and the wetsuit in 1952 by University of California, Berkeley physicist, Hugh Bradner and its development over subsequent years led to a revolution in recreational diving. However, for much of the 1950s and early 1960s, recreational scuba diving was a sport limited to those who were able to afford or make their own kit, and prepared to undergo intensive training to use it.
Sport Diving is an underwater sport that uses recreational open circuit scuba diving equipment and consists of a set of individual and team events conducted in a swimming pool that test the competitors’ competency in recreational scuba diving technique. The sport was developed in Spain during the late 1990s and is currently played mainly in Europe. It is known as Plongée Sportive in French and as Buceo De Competición in Spanish.
The international rules of competition contain the following four objectives for Sport Diving - firstly, encourage the further development of recreational scuba diving equipment and technique; secondly, promote scuba diving activities in localities that are remote from suitable diving sites or where open water activity may be prohibited by seasonal or adverse weather conditions; thirdly, to provide an opportunity for recreational scuba divers to practice and improve technique; and fourthly, the promotion of scuba diving carried out in swimming pools as a spectator sport for underwater diving enthusiasts.
