Extended Range & Trimix Diver (Normoxic)

Extended Range & Trimix Diver (Normoxic) – Group of two or more $1100 each / Private $2200 (book and gear not included)

TDI Extended Range Diver
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

TDI Trimix Diver (Normoxic)
As your motivation to explore progresses you will find that you may want to go deeper to dive that wreck that is part of history or that cave system that you have read so much about. One of the major limiting factors of going deeper is narcosis; TDI's Trimix Diver course shows how to minimize the effects of narcosis by adding helium to offset the nitrogen in your breathing gas. While taking the Trimix Diver course your TDI Instructor will teach you how to plan and execute dives utilizing as little as 18 percent oxygen and diving to maximum depth of 60m/200 feet with a blend of helium appropriate for the planned depth. The course covers topics and skills like:

  • Dive team planning
  • Gas matching
  • Cylinder labeling
  • Surface marker deployment
  • Equipment configuration
  • Thermal protection options
