This  Course qualifies divers to use enriched air nitrox from EAN 21 through EAN 100 to a depth of 40 metres/130 feet during dives that do not require staged decompression. Often taught in conjunction with the TDI Decompression Procedures course, this can be considered the foundation of your technical scuba diving skill-set. Advanced Nitrox Scuba Diver is also a great course for those wanting to extend your bottom times in shallower depths such as scientific diver, and a must for those interested in becoming SCR or CCR divers. The course cover topics like...

Equipment requirements
Dive planning
Oxygen toxicity tracking
Blending methods

You will use the TDI Advanced Nitrox Diving manual for your course, which explains in an easy to understand practical manner the complex information that Advanced Nitrox divers need to know. 
Prerequisites:  18 years old, TDI Nitrox Diver or Equivalent, 25 logged dives.

Open Water Dives:
Four dives are required with a minimum accumulated bottom time of 100 min.
If Advanced Nitrox is taught in conjunction with Decompression Procedures only a total of six dives are required with a maximum depth of 45  meters / 150 feet.
Only 2 dives from Advanced Wreck course may be credited.
Material:
Technical Divers International Advanced Nitrox Student Manual.
Required Diver Performance and Requirements
Maximum training depths shall not exceed 130 fsw. The following open water skills must be completed by the student during all open water dives:
