Advanced Nitrox

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.

Advanced Nitrox is also a great course for those recreational divers wanting to extend their bottom times in shallower depths.

It is however, often taught in conjunction with the TDI Intro To Tech.  This can be considered the foundation of your technical diving career.

  • Equipment requirements
  • Dive planning
  • Oxygen tracking
  • Blending methods

  • Advanced Open Water Diver certification
