Computer Nitrox Specialty
No dives are required for this course
Nitrox diving opens up a new world of increased bottom time and safety if used to build conservatism into your dive plans. Nitrox is any mixture of nitrogen and oxygen including air but Nitrox usually means increased oxygen percentages in your diving gas. More correctly referred to as Enriched Air Nitrox (EAN), this increased oxygen reduces your nitrogen uptake under pressure and therefore extends the no-decompression limits (NDL) for a specific dive plan/depth.
Often EAN is thought to be a deep diving gas but this is incorrect in fact, at partial pressures above 1.4 oxygen can become toxic and cause seizures which is very serious under water. Detailed training is required in the correct use of EAN.

Certified divers looking to advance their knowledge and skill set
