Nitrox Course Online

The Enriched Air Nitrox courses, or nitrox for short, will teach you how to safely plan and dive with enriched air mixtures of up to 40% oxygen. Diving on Koh Tao or anywhere with nitrox can increase your no-decompression limits, reduce the required length of your surface intervals when compared to air and increase your safety.  There are 2 nitrox courses 32% and 40%, both have different SSI certifications but you can take the Enriched Air Nitrox 32 completely online, including the exam.  If you dive with an SSI school you can get a free upgrade to Enriched Air Nitrox 40 once you are shown how to analyse the nitrox mix

What is the course about?

The nitrox course is my second or third suggested course after your open water course on Koh Tao.  The other is the advanced course.  By adding oxygen and reducing the nitrogen in your tank and there by default reduce the load in your body, you gain longer bottom times.  If you are doing many dives over a short period such as a holiday or a liveaboard /A lower nitrogen load is especially desirable if you do several dives within one day for example on a liveaboard.

Enriched Air Nitrox 32 is an academic course only, you will be able to use up to 32% nitrox but still plan your dive based on air, the dive shop will also be responsible for analysing the air.  If you are able to go diving with an SSI school you will get a free upgrade to Enriches Air Nitrox 40 when you can start diving again.  On this second course you will learn to use and analyse enriched air as a breathing gas, to plan your dive and dive your plan with nitrox, and understand how nitrox affects you beneath the surface.
