The Divemaster course is the first professional level dive training course. It is a turning point in a diver's education, as it shifts the focus during diving from oneself to those around. The course is rewarding, but very demanding. It involves among other things a theoretical module, the completion of several watermanship skills, a complete dive skills circuit, as well as underwater guiding and assisting on a number of diving courses. Those who have completed the course become qualified to work as professional dive guides and can assist instructors that conduct diving courses.
