Extend your bottom time on the deeper Andaman reefs and wrecks around Krabi with the PADI Enriched Air (Nitrox) specialty, taught from the Ao Nang dive base. You learn to analyse, plan and dive with enriched-air mixes so you can stay down longer on busy sites like the Phi Phi reefs and shorten surface intervals between dives. You finish certified to dive enriched air up to 40 percent oxygen.
The PADI Enriched Air (Nitrox) specialty can be completed without open-water dives in some formats. It certifies you to use mixes up to 40 percent oxygen and counts toward the PADI Master Scuba Diver rating.
Enriched air is most useful on Krabi's deeper reefs and wrecks reached by speedboat from Ao Nang, such as the Phi Phi sites, where longer bottom times help you get the most out of the warm, clear November-to-April conditions.
