The Enriched Air Diver course is the most 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 (Junior) 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.
