Enriched Air (Nitrox) Course🫧
Enriched Air Diver
Every diver should consider taking the PADI Enriched Air Diver course because it is one of the most practical specialties you can add to your diving.
By learning to dive with nitrox, you can extend your no-decompression limits, enjoy longer potential bottom times, and shorten surface intervals. That means more flexibility, more dive opportunities, and a more efficient overall dive day.
This course also teaches essential safety skills like using an oxygen analyzer and setting your dive computer correctly for enriched air, so you know exactly how to use nitrox confidently and responsibly.
Nitrox is one of those specialties that gives you a real-world benefit on trip after trip. Once you have it, you will use it all the time.
Why This Course Matters
The Enriched Air Diver course improves both safety and enjoyment underwater.
By reducing the amount of nitrogen you take in compared to standard air, nitrox can help extend your no-decompression limits and reduce your surface interval time in many diving scenarios.
That makes it especially valuable for dive trips, repetitive dives, and any situation where you want to make the most of your time in the water.
What You’ll Learn
- How enriched air nitrox works and why divers use it
- How to analyze the oxygen content in your cylinder
- How to set your dive computer correctly for nitrox
- How nitrox affects no-decompression limits and dive planning
- How to use enriched air safely and effectively
- Why this specialty is one of the most practical certifications to have
Why Take Enriched Air?
Because it gives you benefits you will actually use.
This is not just another card in your wallet. Nitrox is one of the most useful specialties in diving because it can increase flexibility in your dive planning, improve repetitive dive profiles, and help you get more out of dive travel.
It is one of the easiest “yes” specialties for divers who want something practical and immediately valuable.
What Changes After the Course
You start planning dives differently.
You begin looking at profiles, surface intervals, and repetitive dives with a much better understanding of how to maximize your opportunities while still diving conservatively and safely.
It is a specialty that pays off again and again, especially on trips where every extra bit of dive time matters.

✅ Dive with nitrox
The PADI Enriched Air Diver course teaches you how to dive with nitrox, which is a type of breathing gas that contains a higher percentage of oxygen than regular air. You'll learn how to analyze nitrox cylinders, plan dives to maximize your bottom time, and use dive tables or computers to avoid oxygen toxicity. The course also covers the benefits of using nitrox, such as extended no-decompression limits, and the specific procedures for safely handling and using enriched air.

✅ Set your dive computer
In the PADI Enriched Air Diver course, you'll learn how to set up your dive computer to work with nitrox. This involves inputting the correct oxygen percentage for the mix you're using, which allows the computer to calculate accurate no-decompression limits and optimize your dive plan. You'll also be trained to adjust the computer’s settings for various nitrox mixes and understand how to interpret the data it provides to ensure safe diving practices.

✅ Use an oxygen air analyzer
The PADI Enriched Air Diver course teaches you how to use an oxygen analyzer to measure the oxygen content in your nitrox cylinders. You'll learn how to properly calibrate and operate the analyzer, ensuring accurate readings of the oxygen percentage. The course also covers how to interpret the results to confirm that your dive mix matches your planned parameters, which is crucial for safe and effective diving with enriched air.
