If you want to shorten your surface intervals and extend your dive time, join the Enriched Air Nitrox Specialty program. As a Nitrox diver, you can increase your bottom times and safety margins, plus shorten your surface intervals - so you can spend more time exploring the dive sites you love and less time waiting to dive. It’s the perfect course to get the most out of your dive time, especially on multi-dive days, and helps minimize diver fatigue. In this program, you’ll learn new skills and increase you diving knowledge whilst learning how to safely plan and dive with enriched air mixtures of up to 40% oxygen. Upon completion, you’ll earn an SSI Enriched Air Nitrox 32% or 40% certification.
