TDI Extended Range
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
This course is run over four days and consists of one day of theory and equipment workshop if required plus three full day’s boat diving with a total of six dives
To enroll in the TDI Extended Range you must
- Be a minimum age of eighteen (18)
- Minimum of 100 logged dives, of which 25 must be deeper than 100 fsw / 30 msw
- Certification as a TDI Advanced Nitrox and TDI Decompression Procedures Diver (or equivalent) are required.
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).
