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

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).

Course Pre-requisites:

• Be a minimum age of eighteen (18).
• Be certified as a TDI Advanced Nitrox Diver and TDI Decompression Procedures Diver (or equivalents) is required.
• Have a minimum of one hundred (100) logged dives, of which twenty (25) must be deeper than thirty (30) msw / one hundred (100) fsw.
