Longer Bottom Times. Shorter Surface Intervals. These are among the many benefits of diving Nitrox
— a mixture of nitrogen and oxygen in which the concentration of oxygen is greater than that found in air. You’ve
no doubt heard of Nitrox, probably know divers who use it. You also know that using Nitrox safely requires special training
Traditionally, becoming a Nitrox Diver required long hours in the classroom, learning how
to work obscure formulas and use complex dive tables. No more. Through SDI’s on-line training program, you can complete
most of the required academic study in the comfort and convenience of your home or office. And, as with all SDI programs,
you’ll learn to dive Nitrox the modern way, using Nitrox-programmable dive computers instead of arcane formulas and
When you are done with the self-study portion of the course, you will meet with your SDI instructor
to review your final exam (academic review) and to take part in a brief, practical application session. Here you will get
hands-on experience with oxygen analyzers and Nitrox computers. Your instructor may even provide you with the opportunity
to make one or more Nitrox dives.
When you have completed the academic review and practical application sessions, your SDI Dive Center
will order your permanent certification card. What could be easier? Nitrox opens a world of possibilities, leading to better,
more enjoyable diving. What are you waiting for?
