Stay A While

Enriched air, also known as nitrox or EANx, contains less nitrogen than regular air. Breathing less nitrogen means you can enjoy longer dives and shorter surface intervals. No wonder Enriched Air Diver is the most popular PADI specialty.

What You Learn

Learn why nitrox allows you to make longer dives and how to dive nitrox safely through online independent study. Meet with your PADI Instructor for hands-on practical exercises, then make two (optional) dives.

After finishing your academic study, you’ll learn how to analyze a tank, fill out an enriched air log, and set your dive computer for nitrox. There are two optional dives.
