Enriched Air (Nitrox) Certification
Extend your bottom time and shorten surface intervals with Enriched Air Nitrox! Since nitrox contains a lower percentage of nitrogen than regular air, your body absorbs it at a slower rate—allowing for longer dives and less time spent waiting between them.
During your Nitrox Certification Course, you'll learn how to safely plan and execute nitrox dives, including essential safety protocols. One of the most crucial skills you’ll master is analyzing your nitrox mix before any dive to ensure you’re using the correct oxygen blend.
Many resorts and dive operators offer "Free Nitrox" as a perk, meaning there’s no extra charge for using nitrox. However, you must present a valid nitrox certification to take advantage of this benefit.
This course is a must-have specialty for divers of all levels.
