Become an SSI Nitrox diver

As a Nitrox diver, you can increase your bottom times and safety margins, plus shorten your surface intervals – so you can spend more time diving and less time waiting! In this program, you will learn new skills and increase your diving knowledge whilst learning how to safely plan and dive with enriched air mixtures of up to 40% oxygen.

Upon completion, you will earn an SSI Enriched Air Nitrox 32% or 40% certification.

Sign up for Enriched Air Diver Online . The web-based system covers all the enriched air diver course content and allows you to study at your own pace through an easy-to-use, interactive program. 

Most modern scuba equipment and dive computers can be used with enriched air, but your Instructor will let you know if your gear meets manufacturer recommendations and local requirements. However, scuba tanks must meet oxygen service standards and be dedicated for use with enriched air. You’ll practice using oxygen analyzers and special cylinder decals. Your  Dive Center or Resort staff will explain other equipment you may need to enjoy enriched air diving.
