Have you ever wondered about nitrox?
For those of you who are nitrox certified and dive regularly with this specially enriched air with the telltale green and yellow dive cylinders, you will know the secret. For those of you who don't, read on.
What is nitrox?
Nitrox refers to any gas mixture composed of nitrogen and oxygen. This includes atmospheric air, which is approximately 78% nitrogen, 21% oxygen, and 1% other gases.
By upping the oxygen in a scuba cylinder, the amount of nitrogen is reduced.

How do I get certified?
The nitrox course is a 'dry' course, which means that you don't have to do a dive to get your nitrox certification, unless you want to, of course.
The steps involved are:
- Review the medical questionnaire. (A 'YES' on the medical form will require clearance from a doctor.)
- Watch a nitrox DVD. (Can be done while you are on the island.)
- Read the nitrox manual and complete the knowledge reviews inside. (The manual will be yours to keep.)
- Finally, sit for a short exam to test your newfound knowledge.
- Analyze a tank with your instructor.
The cost of the course is $125.00 USD. This includes the manual, exam, certification card, instruction, as well as one tank to give it a try.
Nitrox is charged at $10.00 USD per tank on the boat and $12.00 USD per tank for shore dive rentals.
