Certain areas of the world provide spectacular dives at depths deeper than 40 meters (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 55 meters (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).
