Advanced-nitroxThe advanced nitrox course takes you beyond the foundations of intro to tech or sidemount, and technical diving procedures to prepare you for decompression diving. It introduces the use of enriched air nitrox (EANx) mixtures from 40% to 99%, and pure oxygen (100% O2), for optimal mixtures to depths not exceeding 40m/130ft.

The course trains you in the benefits, hazards a
nd proper procedures for utilising air, EANx 22%-99%, and oxygen for dives not requiring staged decompression. It builds on concepts and practices introduced in the Basic Nitrox course, as well as detailed coverage of Central Nervous System (CNS) and whole of body oxygen toxicity tracking, common mixing methods, computing best mixes for planned depths, benefits and limitations of hyperoxic gase mixtures, dive planning procedures, calculating gas requirements, and additional equipment considerations. At the completion of the course, successful candidates will be certified to use nitrox mixes from 22% - 99%, and pure oxgyen (100% O2) as a breathing gas.
