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 cover topics like

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