Actually Nitorx is quite a simple concept and is no longer being considered as a Technical Diving discipline, PADI even offer a course which you can start in conjunction with your Open Water Diver Course!!! Enriched Air Nitrox is just a blanket term we give to any mix of breathing gas which has more than the normal 21% Oxygen in it.
What does this extra Oxygen do for us?
Well, regular air (the same stuff you normally fill your SCUBA cylinders with) comprises of 21% and around 79% Nitrogen, so if you raise the amount of Oxygen in the mix you in turn lower the amount of Nitrogen in there as well. For example if you have 32% oxygen in the cylinder then there is only room for 68% Nitrogen or if you had 36% Oxygen the there is only room for 64% Nitrogen. Now with Less Nitrogen in the cylinders this mean as we dive our bodies will absorb Nitrogen more slowly which means we can stay down a little longer looking at all the amazing things the Celebes Sea has to offer us.
Unfortunately there is a small downside in that because of the extra Oxygen present you can't go quite as deep as you can with a normal air mix. This difference in maximum bottom depth varies depending on how much Oxygen you have in your mix but with proper training as offered in the PADI Enriched Air Diver Course you will learn many simple procedures to plan around this, in fact using a dive computer it only takes a few minutes more to plan your dive safely. As with any dive so long as you follow the rules you learn in the course and plan your dive properly the benefits far out ways the risks.
Well first step is to book onto an Enriched Air Nitrox course which we can help you to do at many of the resorts we work with. The course is typically 2 dives with a half day of theory, wich most places will fit in between your normal diving schedule so you don't have to miss even a minute of Bottom time stuck in the classroom. Once that is out of the way you can start to enjoy your added bottom time on all your dives.
