What is the primary benefit of using Enriched Air Nitrox (EANx) for recreational diving?

The primary benefit of using Enriched Air Nitrox (EANx) for recreational diving is that it allows divers to increase their bottom time due to reduced nitrogen absorption. Nitrox mixtures typically have a higher oxygen content and a lower percentage of nitrogen compared to regular air. This reduction in nitrogen decreases the amount of nitrogen that the body absorbs during the dive, which, in turn, leads to a lower risk of nitrogen narcosis and decompression sickness. Consequently, divers can enjoy longer dives at shallower depths without the same level of nitrogen loading associated with air, maximizing their underwater experience.

This aspect is crucial for divers who wish to extend their time exploring underwater environments before reaching their no-decompression limits. The use of EANx is particularly beneficial for repetitive dives or when diving in locations where longer dive times enhance the overall experience, such as visiting extensive coral reefs or historical wrecks.
