CMAS two-star scuba diver (also known as CMAS P2 diver[citation needed], CMAS** diver, or just CMAS**) is a diving certification for recreational scuba diving issued by the Confédération Mondiale des Activités Subaquatiques (CMAS).
It indicates that the diver has been assessed as competent to plan and undertake dives to a maximum depth of 30 metres, or with some additional experience, 40 meters, accompanied by another diver with a recognised equivalent or higher certification, with no requirement for a dive leader.[1]
