Divemaster Course



The Divemaster Course is the first professional-level certification. During the course, you will learn how to work with divers, lead certified divers, and act as a dive guide showing divers underwater dive sites and the marine life that inhabits those dives sites. You will increase your knowledge about physics and physiology, as well as increase your proficiency with your scuba and snorkelling skills. You will get to learn how to guide dives, assists on courses and charters. Once completed, you will be ready to enrol on the instructor courses. 

All Divemaster students dive free on our local charters throughout their course period to help them increase their hours and skill levels.
