Have you ever wondered about those tanks with a yellow-green label on the back of divers, but never had a chance to chat with them about the difference between air and enriched air?
The benefits of diving with Nitrox and how to get your license? It is much easier than you think!

SO WHAT’S NITROX?

The air that we breathe on the surface and the air from a scuba tank have the same mixture of gases, 21 percent oxygen and 79 percent nitrogen, minus some traces of other gases. In other words, Nitrox 21. If the nitrogen-oxygen gas mixture has a higher oxygen concentration than those 21 percent, it’s referred to as enriched air (EAN). The most common mixture is Nitrox 32, which contains 32 percent oxygen and 68 percent nitrogen.

Tanks that are filled with enriched air are generally clearly marked with a band and/or a sticker indicating the percentage of mixing.
