About This Adventure
Become a NAUI Enriched Air Nitrox diver and enhance your diving experience! This course teaches you to safely use Nitrox, extending your bottom time and optimizing each dive. Learn about gas mixing, oxygen physiology, and dive planning through engaging eLearning and virtual classes, preparing you for exciting underwater adventures.
Do you want to extend your bottom time, shorten your surface interval, and maximize every dive? Become a NAUI Enriched Air Nitrox diver!
During this course, you will learn how to choose the proper blend of Nitrox for your dive profile, determine maximum depth limits for your Nitrox mixture, analyze your breathing mixture, and plan and safely execute each dive. Your instructor will teach you about the physiology of oxygen and nitrogen; advantages, disadvantages, and risks of nitrox; oxygen toxicity; hazards and precautions of handling oxygen; the concept of Equivalent Air Depth; use of EANx with standard Air Dive Tables; common gas mixing procedures; and more.
Minimum age for participation is 10 years (Junior EANx certification) or 15 years (EANx certification). Upon successful completion of this course, graduates are considered competent to utilize EANx (up to EAN40) in open water diving activities without direct supervision.
Your course will begin with NAUI eLearning, including topic quiz's and a final exam. You are required to complete your eLearning prior to your scheduled class meeting (approx. 1-2 hours). During your class meeting we will review the following list of topics:
• History of nitrox as a breathing gas • Dalton’s law of partial pressures • Physiology of oxygen and nitrogen • EANx depth limits, • EANx advantages, • EANx disadvantages • EANx risks • Oxygen toxicity • Hazards and precautions of handling oxygen • Equivalent Air Depth • Use of EANx with standard air, EANx, or RGBM-based dive tables • Common gas mixing procedures • Gas analyzing procedures. • Dive Planning
The classroom portion of this course will be conducted virtually on the date & time of your booking.
Adventure Tips
Understand Your Limits
Nitrox extends no-decompression limits but does not eliminate the need for safe dive planning and adherence to depth and time limits.
Complete eLearning Before Virtual Classes
Finish the online modules first to maximize your understanding during interactive sessions.
Check Your Gear for Oxygen Compatibility
Ensure your regulator and dive equipment are rated for enriched air to avoid damage or safety issues.
Hydrate Well Before Diving
Increased oxygen levels can lead to dehydration; drink plenty of water before and after dives.
