Enriched Air Nitrox is the most popular specialty available. It is usually marketed as having two main benefits. Firstly, it can be used to extend bottom times, particularly in the 20-35mtr range. It also has a legitimate reputation for increasing safety margins if used with air profiles.

Both of these benefits are true and because we are regularly using Nitrox for both bottom mixes, rebreathers and decompression diving we will teach you how to get the most benefit from using it.
