Air is a combination of 79.1% nitrogen and 20.9% oxygen. Nitrox is a special blend of nitrogen and oxygen with increased oxygen levels. This course certifies you to use up to 40% oxygen. The benefits of nitrox are less nitrogen on-gassing and decreased surface intervals. Use of nitrox when making repetitive dives over multiple days adds a safety margin and can make you feel a little less tired at the end of each day.
We will teach you about the physics and physiology of diving Nitrox, Nitrox equipment, and planning Nitrox dives.
