MORE BOTTOM TIME. LESS NITROGEN.
Enriched Air Nitrox (EAN) replaces a portion of the nitrogen in your breathing gas with oxygen — reducing nitrogen absorption and extending your no-decompression limits at any given depth. The result: longer dives, shorter surface intervals, and reduced post-dive fatigue.
This is the most popular SSI specialty certification worldwide, and for good reason. It is a straightforward course that immediately improves every dive you do from the moment you complete it.
EXTENDED NO-DECO LIMITS
Dive longer at your target depth within recreational limits. Nitrox 32% extends your NDL at 18m from 56 to 95 minutes.
SHORTER SURFACE INTERVALS
Lower nitrogen loading means you can return to the water sooner — ideal for multi-dive days in Cancún and Cozumel.
REDUCED POST-DIVE FATIGUE
Less nitrogen absorbed means less off-gassing fatigue. You feel better at the end of dive days — and the next morning.
