Enriched Air (theory only)

Diving with Enriched Air NITROX

Note: This is only the theory course. No dives are performed.

The Enriched Air Diver course is a popular specialty scuba course. Why? Because scuba diving with enriched air nitrox gives you more no decompression time, especially on repetitive scuba dives. If staying down longer and getting back in the water sooner sounds appealing, then don’t hesitate to become an enriched air diver.

If you’re a Open Water Diver who is at least 12 years old, you can enroll in the Enriched Air Diver Specialty course. Note that in some regions the minimum age is older than 12.

What will you learn?

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.

What gear will you use?

Most modern scuba equipment and dive computers can be used with enriched air, but your 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 Dive Center staff will explain other equipment you may need to enjoy enriched air diving.
