Nitrox Diver

Nitrox Diver



The Nitrox Diver course enables divers to breathe compressed air with a higher than normal % of oxygen. It will provide the scuba diver with the knowledge and skill to dive with nitrox mixtures from 22 to 40 percent oxygen.

Diving with Nitrox can increase your no-decompression limits, reduce fatigue, reduce the effects of nitrogen narcosis, and reduce your chances of decompression sickness if followed properly. Nitrox diving is gaining popularity at resorts, live aboard boat operators and local dive shops. Diving with Nitrox gives you the extra-added safety cushion if followed properly.

Must be a certified Open Water Diver or enrolled in the Open Water Diver course in order to enroll in the Nitrox course. So you can complete the Nitrox course prior to heading out for your open water dives!
