Extend your no-decompression limits and enjoy underwater exploration for longer by breathing enriched gas mixtures of up to 40% oxygen.
Do you want to explore the underwater world longer, but your no-decompression limits won’t allow you? Or maybe you just want to stay safer and decrease the risk of decompression sickness by breathing less nitrogen?
Both reasons are good enough to obtain an EANx course and become an aware diver.
Throughout this course, you will learn how to plan and execute dives with different gas mixtures, up to 40% of oxygen.
One of the biggest benefits of breathing Nitrox is a reduced amount of nitrogen – the inert gas that is responsible for our No-Decompression-Limits and potential decompression sickness.
Becoming an Enriched Air Nitrox Diver is a matter of acquiring knowledge that usually takes about 3 hours. During the nitrox course, we will talk about what Nitrox is and all the advantages and limitations associated with breathing this gas.
You will better understand the partial pressures of gases, so you will be able to calculate the MOD (Maximum Operating Depth) to be sure you won’t go beyond safety limits.
You don’t need any special equipment to dive with nitrox, the only thing that changes is the contents of the back tank, which you will have to analyze.
You will understand how Nitrox impacts your diving system, and how to verify the tanks that contain different mixture of gas than air by cylinder markings.
Another important part would be understanding what rules and procedures should you follow for safe Nitrox cylinder dealing.
If you would like to practice diving with the stage tank (additional bottle clipped on a side of a diver’s harness) for accelerated decompression – ask for a training dive.
Diving with Nitrox does not require special underwater skills, however, you will have to learn how to use the analyzer to analyze Nitrox cylinder content.
We will teach you, how to properly use Nitrox-programmable dive computers and dive tables to safely plan your dives, as well as, managing exposure to oxygen and nitrogen.
Usually, the Nitrox course is land-based and does not include dives. This is a dry course, meaning there won’t be any diving during the training, and no additional skills are required—everything remains the same except for the gas mixture in the cylinder. However, if you’d like to enhance your experience, we offer two additional Nitrox boat dives for an extra 2,500 baht.
After completing this course you will become an Enriched Air Nitrox diver which allows you to dive with different gas mixtures of up to 40% oxygen.
Nitrox is a mixture of nitrogen and oxygen – just like air, but in different proportions.
When the air contains 21% oxygen and 79% inert gases (mainly nitrogen), nitrox is a mixture containing more oxygen and less nitrogen.
One of the most popular blends is EAN32, which means the mixture contains 32% oxygen and 68% nitrogen.
The reason why divers use nitrox is to reduce inert gases, such as nitrogen, so that they can extend their No-Decompression Limits, or simply reduce the risk of decompression sickness (DCS), which is caused by these gases.
It is worth taking an Enriched Air Nitrox course, especially if you want to reduce the risk of decompression sickness or extend your bottom time.
This course includes theoretical and practical classes that will increase your awareness of the gases we breathe, which is extremely important in your diving development.
The Enriched Air Nitrox specialization can be completed in 3-4 hours.
This course does not require any educational dives, as nothing changes except the gas mixture, which you will need to analyze as part of your training. However, we recommend that you take the opportunity to dive with an instructor to update some diving skills.
The Enriched Air Nitrox course costs THB 5.000 and includes theoretical and practical classes, as well as digital learning materials and a certificate.
We offer two training dives for students who want to improve their diving skills for an additional 2,500 baht. These dives can take place either in the pool or as two boat dives—it’s your choice!
The main reason divers use nitrox is safety. As we have already mentioned, nitrox is a mixture containing more oxygen than regular air – we use it to reduce the amount of nitrogen – the gas responsible for decompression sickness.
Absorbing less nitrogen reduces the risk of decompression sickness (DCS), while increased oxygen intake raises the risk of oxygen toxicity. That’s why it’s crucial to gain knowledge and skills through the Enriched Air Nitrox program to learn how to calculate your maximum operating depth and choose the best mixture for your dive ensuring safety at all times.
Decompression sickness is caused by an inert gas such as nitrogen.
By reducing the amount of nitrogen, we reduce the risk of DCS, although there is never a guarantee that decompression sickness will be prevented.
After completing this course, you will become an SSI Enriched Air Nitrox diver, which allows you to dive with gas mixtures with an oxygen content of up to 40%.
