NITROX
NITROX TRAINING
Want to stay a little LONGER, go a little DEEPER or explore FURTHER? Experience new adventures beyond the limits? Enter the world of decompression and train in decompression diving with super-oxygenated mixture for greater safety.

SSI REGISTER
BLUE SEA DIVERS SEYCHELLES DIVING SCHOOL IS THE ONLY CENTRE IN SEYCHELLES TO OFFER NITROX TRAINING.
The air we breathe and which is contained in “normal” compressed air cylinders contains 79% nitrogen and 21% oxygen (intentionally ignoring the share of rare gases and rounding the figures).
Nitrox (or enriched air, or EANx …) is enriched with oxygen. This means that the oxygen level is higher than 21%. As a general rule, bottles filled with Nitrox contain between 32% and 36% or even 40% oxygen. The nitrogen level is therefore only 68%, 64 or 60% at most.

We therefore increase the percentage of oxygen in order to reduce the percentage of nitrogen, the main cause of desaturation accidents.
Dives with accessible rigor, proven safety with a mixture of 21 to 40%.
THE ADVANTAGES OF NITROX ARE MULTIPLE:
Less nitrogen than air diving
More efficient landings
Less risk of desaturation accident
Less fatigue
An increased safety curve
To enjoy diving trips and diving cruises in complete safety.
HOW TO DIVE WITH NITROX?
You just need to pass the SSI Enriched AIR Air Enrichi specialty, accessible:
For Open Water Divers (or equivalent certification).
For students taking their Open Water Diver, it is possible to take the Enriched Air specialty at the same time.
For persons aged 15 and over.
You will learn, among other things, the specificities of enriched air diving with Nitrox, considerations regarding depth, but also equipment.
In particular, you will learn how to analyze your air, that is, how to know the oxygen level in your tank for your upcoming dive. This is the exact level that you will enter into your dive computer. We insist on the fact that the analysis of the air in your tank must be done systematically before each of your dives and by yourself, not by someone else. Safety must always be a priority.

IS SPECIFIC EQUIPMENT REQUIRED FOR DIVING WITH NITROX?
You will dive with tanks clearly marked as containing Nitrox.
So, are you motivated to get started? And for divers already certified Nitrox, what are your impressions of diving with normal air?
Nitrox training includes:
– Gas analysis before diving
– A dive with a 40% superoxygenated mixture
– Digital theoretical course via a dedicated application
– Digital certification
