Our Divemaster’s

Our Divemasters will give you a boat briefing and an overview for the day at the time the boat starts. They will give you a Dive briefing before each dive, and be in the front to lead the group while diving. Ask you frequently for Air consumption and knock against the Tank to get your attention. If there is any problem they will assist you, to secure your and others safety. If you and your buddy would like to explore the dive-site yourself the Divemasters will give you a briefing on the boat and check the predive safety procedure before your buddy team enter the water.
