Dive Longer, Safer & Smarter

Expand your diving adventures with the SSI Recreational Nitrox Diver Course. Learn how to safely dive with enriched air nitrox and discover why it is one of the most popular scuba certifications in the world.

This course teaches you how to analyse your breathing gas, correctly label your cylinder, plan nitrox dives, understand oxygen exposure limits and confidently configure your dive computer for nitrox diving.

Taking only half a day to complete, we normally incorporate this specialty into a package with other courses, like the Open Water course or the Advanced Adventurer course.

Just like air, Nitrox is an air mixture of oxygen and nitrogen. However, in a nitrox gas mixture we will increase the oxygen percentage in a mixture to more than 21%, causing it to be “richer”.  

Diving with enriched air can increase your no-decompression limits, increase your safety and reduce the required length of your surface intervals when compared to air.

You will earn the Enriched Air Nitrox 40% certification after completing this program.
