As a Nitrox diver, you can extend your bottom times or safety margins and, of course, shorten surface intervals—so you can spend more time exploring the dive sites you love most and less time waiting! In this program, you’ll learn new skills and expand your diving knowledge while learning how to safely plan and dive with enriched air mixtures containing up to 40% oxygen. Upon completion, you’ll earn the SSI Enriched Air Nitrox 32% or 40% certification.
