By diving with enriched air rather than standard air you can extend your no decompression limits. This means more time underwater. For example, if you dive to 15 metres/50 feet on air, your no decompression limit is 80 minutes. But, diving on EANx36 gets you 220 minutes of no decompression time – an increase of 140 minutes.
