To provide the diver with a good understanding of the techniques involved in the use of Nitrox mixtures for bottom and/or decompression use, including the use of pure oxygen for decompression purposes.
To make the diver aware of the additional physiological problems encountered when using Nitrox mixtures and pure oxygen.
appropriate to diving with Nitrox mixtures and pure oxygen.
To provide the diver with the opportunity to gain further experience using Nitrox .
Minimum duration of course is 2 days, with the number of class room sessions being 5. The minimum classroom duration is 6 hours.
The minimum number of 2 dives are required with one dive to include the use of oxygen during decompression.
This course will be a regional course run by qualified Advanced Nitrox [ AdvEAN ] instructors. This course must be lead by an Approved Advanced Nitrox Instructor [ approved by the National Nitrox Coordinator ] , assisted either by other Approved AdvEAN Instructors or instructors gaining their qualification.
The number of ‘Assistant Instructors’ must not exceed the number of Approved AdvEAN Instructors. A register of Approved AdvEAN Instructors is maintained by the National Nitrox Coordinator at Head Office.
Suitable classroom with teaching aids for formal presentations.
