Why Nitrox?

Nitrox is simply air in which the partial pressure of oxygen has been increased beyond the 21% normally found in air. Nitrox is created either through the addition of pure oxygen to the mixture, or the subtraction of nitrogen with a membrane system. On our vessels, we use the latter system.

Nitrox diving has many advantages: absorption of less nitrogen into the bloodstream and body tissues, reduced risk of decompression illness for equivalent profiles, and less post-dive fatigue (especially useful on liveaboards!). As with any diving activity, however, diving with nitrox demands careful attention and a special certification.

Enriched air certifications are an excellent chance to improve your skills and knowledge, and take only about 4 hours of your time, in between dives. No special equipment is required, since we only dive with nitrox mixtures containing less than 40% oxygen. Just ask a dive staff member, and he or she will be happy to help!

Diving with nitrox does require that an additional waiver be signed on board, and a log kept of verified gas mixture, maximum planned dive depth, etc. Click here to view the waiver; please note that it only needs to be presented on board, and that we do not need it in the booking office prior to your trip. We have copies on board for your convenience.

Nitrox is offered aboard all of our vessels.
