The PADI Nirox course is PADI’s most popular specialty scuba diving course, and it’s easy to see why. Scuba diving with enriched air nitrox gives you more no decompression dive time. This means more time underwater, especially on repetitive scuba dives.

During this course you will learn the difference between Air content and Nitrox content. You will learn how to analyze tanks with Oxygen mixes up to 40% and how to set your dive computer.

There are many benefits using Nitrox. It extends bottom time but in shallower depths. The more O2 % in the mix the shallower the dive due to concerns with Oxygen Toxicity. With Air you can go to 30 meters and stay here for 20 minutes, with 32% it is 30 minutes and with 36% you will not be able to go to 30 meters but to a maximum depth of 28 meters but stay there  around 40 minutes.
