CMAS* SCUBA Diver,or just CMAS*, is an entry level recreational SCUBA diving certificate issued by Confédération Mondiale des Activités Subaquatiques (CMAS).

The certificate allows diving down to 21 meters, but does not allow night diving or use of nitrox. Both require higher level certificates. CMAS* training is issued by both diving clubs and diving centers, and is awarded by the national diving associations. In the Nordic region, the certificate CMAS* Nordic SCUBA Diver is awarded, as the course is more extensive (at least six dives) and the course includes curriculum for cold water diving.

Freediving, the oldest extreme sport in history yet an emerging sport today. Like whales and dolphins, humans can take a breath and descend beneath the surface of the waves to experience the surreal silence and beauty of any aquatic environment. Unlike marine mammals however, freedivers have to train their bodies and minds to enable them to experience the underwater world in the way our mammalian physiology is designed to, in apnea. And a handful of freedivers choose to push human endeavor even further to defy science and redefine the limits of mankind by diving deeper than ever before.
