RAID Nitrox Diver


Do you want to extend your in-water dive time?
Do you want to gain a better understanding of decompression and use a gas that will allow you to do that?

The answers to these two simple questions are the reason why nitrox is the most popular diver specialty in the industry. Nitrox has proved to be so popular within the diving community that many dive centers offer only nitrox as their breathing gas.

Nitrox use has many benefits for scuba divers. But most divers use nitrox because it helps better manage the risk of decompression sickness. In the Nitrox course, you will learn the pros and cons of using nitrox as a breathing gas for sport diving.

You will learn new skills and extend your diving knowledge, including information such as why nitrox is often a better choice than air. Most importantly, this course will teach you how to plan nitrox dives, what you have to do to stay safe when you use nitrox, and how to analyze and label dive cylinders so that there is never a mix-up.


During the Nitrox program, you will complete the online academics and learn the following:

- How to use Nitrox mixes from 22%-40% Oxygen
- How to plan dives to a planned maximum PO2 of 1.4 bar and a contingency PO2 of 1.6 bar.
- What the causes and effects of Oxygen toxicity are and how to avoid them.
- How to safely analyze the Oxygen content in a Nitrox mix and know the depths at which you can use it.
- How to label your Nitrox cylinder appropriately.
- How to fill in a Nitrox log.
- What the benefits of enriched Oxygen are for sport divers.
