PADI Enriched Air (Nitrox) Course

Boost Your Bottom Time – Extend Your Dive

Tired of having to end your dive early? Using enriched air nitrox is a safe, effective way to increase your nitrogen no-stop limit and extend your dive. 

Enriched air nitrox refers to an air mixture with a higher-than-standard concentration of oxygen. Consequently, the nitrogen concentration is reduced from its normal level. That leaves you with less residual nitrogen built up during your dive day, and significantly extended bottom times as a result. The PADI Enriched Air Nitrox Specialty Course, therefore, is an essential certification course for every serious diver. But that doesn’t mean it is very difficult! In fact, you can complete the PADI Enriched Air Nitrox Specialty in just one day, without the necessity to even go diving in order to earn the certification. During this course, you will learn how to analyze a tank’s air mixture to determine oxygen concentration. From there, you will be able to determine your adjusted no-stop limit and safe maximum depth. Lastly, you will learn how to avoid any risks associated with an increased oxygen content, such as oxygen toxicity. The Enriched Air Nitrox Certification is extremely practical, particularly during repetitive dive days. It will assure your increased safety, along with increased enjoyment at the same time.
