Take your scuba diving to the next level with the SSI Enriched Air Nitrox course—one of the most popular and practical specialty programs for certified divers. Whether you're looking to extend your bottom time, reduce your surface intervals, or simply enjoy more flexibility in your dive planning, this course opens the door to longer, safer dives.

In this course, you'll learn the theory behind using enriched air (commonly referred to as Nitrox), including how increased oxygen levels and reduced nitrogen exposure can enhance your safety and comfort underwater. Through a combination of self-paced online learning and hands-on practice, you’ll gain the skills needed to analyze oxygen content in your tank, manage oxygen exposure, and plan dives with Nitrox mixtures up to 40% oxygen.

This specialty is ideal for divers who want to make the most out of repetitive diving days—whether you're heading out on a tropical dive vacation, joining a liveaboard, or just spending more time exploring your local dive sites.

Upon successful completion of the course, you will earn the SSI Enriched Air Nitrox 32% or 40% certification, allowing you to dive with Nitrox anywhere in the world.
