40%高氧空氣

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.
