As a Nitrox diver you can increase 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 will learn new skills and increase your diving knowledge while learning how to safely plan and dive with enriched air mixtures containing up to 40% oxygen. Upon completion, you will earn the SSI Enriched Air Nitrox 32% or 40% certification.
