TDI Extended Range Diver Course


Certain areas of the world provide spectacular dives at depths deeper than 39m/130 feet but you will not have access (or very limited access) to helium. The TDI Extended Range course teaches you the proper techniques for utilizing compressed air as a breathing gas and with a maximum depth of 55m/180 feet you won’t have to miss those dives.

The Extended Range course will cover topics and skills such as

  • Equipment requirements and configuration
  • Decompression options
  • Use of surface marker buoys
  • Buddy rescue
  • Narcosis checks and management
  • Materials for this course include the TDI Extended Range Diving Manual and the US Navy or Buhlmann Air Decompression Tables (made of vinyl for easy in-water use and storage)
