What is the typical EANx mix used by recreational divers?

The typical EANx mixes used by recreational divers are commonly EANx 32 and EANx 36. These mixes provide a good balance between increased oxygen content and safe nitrogen levels, minimizing the risks of nitrogen narcosis and decompression sickness.

EANx 32, with 32% oxygen and 68% nitrogen, offers longer bottom times compared to air, allowing divers to explore depths of about 30 meters (100 feet) while still maintaining a reasonable safety margin. EANx 36, containing 36% oxygen and 64% nitrogen, is used for slightly shallower dives and provides even more reduced nitrogen exposure, further extending bottom time while decreasing nitrogen loading.

These mixes allow divers to maximize their dive experience safety, making them popular choices in recreational diving. Other options, such as EANx 28 or EANx 40, could be suitable for specific dive profiles or circumstances but are less commonly utilized as standard recreational dives.
