Enriched Air (Nitrox) is air which has been ‘enriched’ with extra Oxygen. The principal benefit being that you won’t be exposed to as much Nitrogen whilst breathing this gas and will therefore enjoy the benefit of an extended no-decompression limit.
It is very common not to use the gas for this benefit, however. Many divers prefer to use Enriched air whilst diving to air limits in order to factor in an extra margin of conservatism to their regular dives. This is especially beneficial to those divers who are not as young and fit as they once were.
Enriched air is particularly good for those with a heavy diving schedule, as it helps to limit Nitrogen loading. It also benefits deep dives where the no-decompression limit could be so short as to end the dive too early.
This course covers both theoretical and operational considerations of using enriched air with 22% – 40% oxygen.
Following certification we will provide you with Nitrox for free throughout the remainder of your holiday (usual price €5/cylinder).
