Enriched Air Diver (Nitrox)
The most popular PADI specialty course. Scuba diving with enriched air nitrox gives you more no decompression time, especially on repetitive scuba dives.
You’ll learn why diving with air that has higher oxygen and lower nitrogen content gives you more bottom time, along with enriched air equipment considerations. During a practical session, and two optional (or required) scuba dives, you’ll:
- Discuss managing oxygen exposure.
- Practice analyzing oxygen content in your scuba tank.
- Set your dive computer for diving with enriched air nitrox.
You may be able to get college credit for the PADI Enriched Air Diver course – ask your instructor to learn more.
Prerequisites & Requirements
12 years or older
PADI Open Water Diver (or qualifying certification)
Approximately 18 hours
Most modern scuba equipment and dive computers can be used with enriched air, but your PADI Instructor will let you know if your gear meets manufacturer recommendations and local requirements. However, scuba tanks must meet oxygen service standards and be dedicated for use with enriched air. You’ll practice using oxygen analyzers and special cylinder decals. Your PADI Dive Center or Resort staff will explain other equipment you may need to enjoy enriched air diving.
