Nitrox: What’s the Difference?


We all know that diving is fun. Fun can sometimes also mean that time somehow moves faster than it should be. Having met an object at a certain depth and trying to take a photo of it can be time-consuming. That is why divers with more experience prefer to use NITROX when they dive. So what exactly is it? And is it really true that you can dive longer? So, Nitrox: What’s the Difference?

What is Nitrox?

Nitrox or Enriched Air Nitrox is a term used to indicate an air content higher in oxygen than usual. In the normal air we breathe and in a regular scuba tank is about 21% oxygen and 79% nitrogen. While the nitrox content of oxygen is higher than 21%. The most common ones being 32% and 36%. With a higher amount of oxygen and a lower amount of nitrogen. Naturally, it means a longer maximum bottom time while diving. But that is not all.


The most benefit you will get is a longer bottom time, because the less nitrogen in the air will increase the time when nitrogen decompression happens. Less nitrogen in nitrox also helps you shorten surface intervals, so more diving in a day. Lastly, it is believed that it can help you reduce fatigue, especially during multi-day dives.


Contrary to popular belief, nitrox cannot actually make you dive longer. Your air consumption rate and the amount of air in the tanks are still the same. So it depends on how you use your air. But remember, you will get longer bottom time.

Next is, can you dive deeper? Technically no, more oxygen in the air can cause oxygen toxicity. Oxygen toxicity can happen after oxygen is exposed to a certain amount of partial pressure of its surrounding. We consumed more oxygen, which means oxygen absorption happens faster and the deeper we go we can absorb it faster than regular air.


Using nitrox is another diving speciality course. Because it is another equipment you will use in your dive that needs more understanding. So are you interested? Take our speciality course here! Or feel free to contact info@balifundiving.com and contact us via WA.
