Enriched Air Nitrox

This is the most popular PADI specialty course. Scuba diving with Enriched Air Nitrox gives you more no decompression time, especially on repetitive dives.

What is Nitrox?

Nitrox is actually any combination of Nitrogen and Oxygen. Regular breathing air is comprised of approximately 21% Oxygen and 79% Nitrogen. Nitrox mixtures with oxygen percentages greater than 21% are called Enriched Air Nitrox (EANx).


Why PADI Enriched Air Diver?

Enriched air, also known as nitrox or EANx, contains less nitrogen than regular air. Breathing less nitrogen means you can enjoy longer dives and shorter surface intervals. No wonder Enriched Air Diver is the most popular PADI specialty.

Scuba diving with Nitrox gives you more no-decompression dive time. This means more time beneath the surface, especially on repetitive scuba dives. While some people use Nitrox to also shorten their surface interval time, we believe you should still relax and enjoy some R&R for at least an hour between dives. 

There are many benefits to diving on Enriched Air Nitrox, but there are also restrictions. This course will teach you everything that’s needed to safely dive on Enriched Air Nitrox, analyze the oxygen content in a scuba tank, and adjust a dive computer to account for Enriched Air Nitrox.


• Extended bottom times
• Shorter surface intervals
• Shorter decompression stops
• Less post dive fatigue
• More dives per day possible
• Nitrogen loading declines as per mix
• Reduced chance of Decompression Sickness
• Reduction in Nitrogen Narcosis
• Safer dives!

Diving with Enriched Air, rather than standard air, extends your no decompression limits. This means more time underwater! For example, if you dive to 15 metres/50 feet on air, your no decompression limit is 80 minutes. But, diving on 36% Enriched Air gets you 220 minutes of no decompression time – an increase of 140 minutes.

What do I need to start?

PADI Open Water Diver certification or current enrollment in the Open Water Diver course.

Minimum Age: 15 Years

What will I do?

PADI Enriched Air Diver Specialty certification emphasizes the theoretical and operational considerations involved with enriched air diving.

How long will the course take?

One academic session prior to the dives.
2 open water training dives over one day.

What will I need?

The Nitrox manual and tanks are part of the course.

The PADI crew pack includes all materials needed — Enriched Air Diver manual, DVD and Computer Dive Simulator access. 

We are the only PADI Dive Center in Trinidad that teach the Enriched Air/Nitrox course.

Where can I go from here?
