  • Description


You’re on the boat looking forward to your days diving and notice some tank cylinders with bright yellow and green bands on them signifying they are filled with enriched air (nitrox). This has got you thinking what are the pros and cons of diving on enriched air, your not the only one as PADI’s enriched air speciality scuba diving course is the PADI’s popular speciality course.

The great thing about diving on enriched air is you can extend your time at depth and build anitorox, enriched air greater safety cushion into your dive plan. Normal air we breath comprises of 21 per cent oxygen and close to 79 per cent nitrogen and less nitrogen in a mix when scuba diving is always a good thing. Here’s an example if planning your dive with PADI’s RDP (recreational dive planner) you plan your dive to 18 meters on normal air the no-decompression limit NDL is 56 minutes with a 32 per cent nitrox your NDL is now 95 minutes even higher on a 36 mix. That means there’s a whole lot more diving time.

We at Lamai Scuba Diving will train you through PADI’s Enriched Air Diver course. We help you understand different gas mixtures, partial pressures and depth limitations. You will learn how to analyse your tanks and plan your dive accordingly to the mixture in your tank. The course is also possible to complete as a theory course without the dives but what’s the fun in just doing the theory so we recommend doing the dives so you can feel the benefits of Nitrox.


You’ll learn why diving with air that has higher oxygen and lowers nitrogen content gives you more bottom time, along with enriched air equipment considerations. During a practical session, and two optional  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.


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.
