Divemaster

A Divemaster (DM) is a diving qualification used throughout most of the world in recreational scuba diving for a diver who has overall responsibility for a group of divers. As well as being a generic term, Divemaster also refers to the lowest professional rating of many training agencies, such as PADI, SSI, SDI, NASE, except NAUI, which rates a NAUI Divemaster just under an Instructor but above an Assistant Instructor.
