TDI Helitrox Diver
The TDI Helitrox Diver Course examines the theory, methods, and procedures for planning staged decompression dives utilizing helium in the breathing mixture to reduce the effects of inert gas narcosis.
The TDI Helitrox Diver Course trains divers how to plan and conduct staged decompression dives to a maximum depth of 45 metres/150 feet. The most common equipment requirements, gear set-up, and decompression techniques are also presented during this course. Students are permitted to utilize enriched air nitrox and helium mixes with no greater than 35% helium content, and up to 100% oxygen for decompression diving.
This program is designed as a stand-alone course, or it may be taught in conjunction with TDI Advanced Nitrox at the discretion of the instructor.
Who this course is for:
- The certified Advanced Diver or Intro to Tech Diver looking to expand their knowledge of decompression theory and diving techniques using helitrox
- The certified Advanced Diver or Intro to Tech Diver who is interested in extending their bottom time
- The certified Advanced Diver or Intro to Tech Diver who has interest in moving forward with technical diving education
- Minimum age 18
- Minimum certification of SDI Advanced Diver (with Deep specialty) or TDI Intro to Tech Diver, or equivalent
- Certified as TDI Advanced Nitrox Diver (unless being taught concurrently)
- Proof of 50 logged dives
