The TDI Advanced Nitrox Course qualifies divers to use Enriched Air Nitrox from EAN 21 through EAN 100 to a depth of 40 metres 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 diving career. Advanced Nitrox is also a great course for those wanting to extend their bottom times in shallower depths such as scientific diver, and a must for SCR or CCR divers.

The course covers topics like:

  • Equipment requirements
  • Dive planning
  • Oxygen 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.
