Extended Range Diver
Certain areas of the world provide spectacular dives at depths deeper than 39 meters 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 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)
