The SSI Enriched Air Nitrox program will teach you how to safely plan and dive with enriched air mixtures of up to 40% oxygen. 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.

If you’re an SSI (Junior) Open Water Diver who is at least 10 years old, you can enroll in the Enriched Air Diver Specialty course.

What will you learn?

If you're interested in longer bottom times and shorter surface intervals, then Enriched Air Nitrox 40 is for you!

Completing the entire program and earning your EAN40 certification provides you with even more knowledge and diving opportunities, and can act as your introduction to the Extended Range Diving program. The physical act of diving with Nitrox is no different from diving with an air-filled cylinder, but safe Nitrox dive planning requires additional education and skills.

This program teaches you the information you need to make educated decisions about diving with Nitrox, including calculating adjusted bottom times, maximum depths and correct surface intervals depending on the Nitrox mixture you use. This program also has a required practical application session, where you will learn the proper techniques and procedures to safely analyze the oxygen content of your Nitrox cylinders, and the precautions required for diving with enriched air.
