Enriched Air (Nitrox) Diver

Sometimes when you’re diving you just want to stay a bit longer. It might be a wreck at 25m that you want to spend more time on, or a special reef that has manta rays at a 30m – if you still have air in your tank you don’t want to have to come up too soon!

Enriched air, commonly called Nitrox, is a blend of oxygen and nitrogen that has a higher percentage of oxygen than normal air. The extra oxygen means that you don’t absorb nitrogen as quickly at depth, meaning you can extend your no-decompression time.

Nitrox gases are used in many areas. Most liveaboard dive boats offer Nitrox facilities, meaning people doing multiple dives over multiple days are absorbing less nitrogen. It is also often used in pony bottles in Victoria when diving deep. In most places you go you are likely to find nitrox airfill facilities, and so this certification is useful all over the world.
