This training course combines the Advanced Nitrox and Deco Procedures Diver training courses to maximum training depths of forty-five meters (45msw) or one hundred fifty feet (150fsw) using Oxygen Enriched Air for bottom mixes and 50%O2 mix for decompression gas. The “built-in” 10 – 12 hours of theory time provides the diver a better grasp of Decompression Illness and Oxygen Toxicity concepts and be able to confidently come up with dive plans that further reduce risks of DCI and O2 Toxicity. The in-water skills and exercises introduce the student diver to innovative techniques in survival, self-sufficiency, and proper decompression management.PART I: The Course starts with a 4 – 5 hours lecture on the following subject matters:
A Review on the History and Development of Nitrox
