Dive leader is the title of an internationally recognised recreational diving certification. The training standard describes the minimum requirements for dive leader training and certification for recreational scuba divers in international standard ISO 24801-3[1] and the equivalent European Standard EN 14153-3.[2] Various organizations offer training that meets the requirements of the dive leader standard. Some agencies use the title "Dive Leader" for their equivalent certification, but several other titles are also used, "Divemaster" may be the most widespread, but "Dive Supervisor" is also used, and should not be confused with the very different status and responsibilities of a professional diving supervisor. CMAS affiliates certifications which meet the requirements of CMAS 3-star diver should meet the standard by default. The occupation of a dive leader is also known as "dive guide", and is a specialist application of a "tour guide".
Scuba dive leaders are considered competent to plan, organise and conduct dives and to lead other recreational divers on open water dives, and for specialised recreational scuba diving activities for which they have been trained. They are also considered competent to conduct emergency procedures associated with these activities and the relevant diving environment. They may require orientation for unfamiliar local environmental conditions. Additional specialised training and experience is required to lead divers on more demanding dives.[2]
The term is also used by BSAC for a specific certification.[3]
