Enriched Air Nitrox Course

The Enriched Air Nitrox course, or nitrox for short, will teach you how to safely plan and dive with oxygen content of up to 40%.

Diving on Koh Tao or anywhere the Nitrox Specialty Course can increase your no-decompression limits, and have shorter surface intervals between repetitive dives when compared to air and increase your safety. And hopefully, give you an overall better diving experience.

What Is The Course About?

The enriched air nitrox course is my second or third most suggested recreational diving course after your entry level open water course on Koh Tao. The other is the advanced course. By adding oxygen content and reducing the nitrogen in your tank you can gain longer diving times. And by increasing your oxygen exposure you are reducing the nitrogen load in your body.

If you are doing many dives over a short period such as a holiday or a liveaboard a lower nitrogen load is especially desirable. But there are limitations on depths of any deep dives.

Once you have paid the deposit you can get access to the digital materials and read all the theories and online exam in advance using the MySSI app on your way to Koh Tao. Once at Mojo Divers we will go through the theory with you again to make sure you understand everything.

After completing the online theory you become an Enriched Air Nitrox 32 diver, at this stage you are not responsible for analyzing the gas mixtures.

To become an Enriched Air Nitrox 40 Diver you will learn to use and analyze enriched air for oxygen percentages as a breathing gas. To plan your dive and dive your plan with nitrox mixtures of up to 40%, and understand how enriched air mixtures affect you beneath the surface.
