Look into the TDI pre requisites for their:
TDI CCR HELITROX DECOMPRESSION PROCEDURES
Who this course is for:
Course prerequisites:
- The certified TDI Air Diluent Diver (or equivalent) who is looking to extend their depth limitations, learn CCR decompression procedures, and reduce narcosis
- The open circuit TDI Advanced Nitrox and Decompression Procedures or Helitrox Diver looking to utilize CCR technology to extend their depth limits and bottom times
- Minimum age 18
- Proof of 50 logged dives
- Minimum certification level of TDI Advanced Nitrox Diver, Deco Procedures Diver or Helitrox diver or equivalent from agencies recognized by TDI
- If the rebreather is a TDI approved sidemount rebreather, the student must hold the TDI Sidemount Diver Certification or equivalent and provide proof of 10 logged sidemount dives
If you look in 'who this course is for' it clearly states that you have to be a "TDI Air Diluent Diver" to do this. Then you have to meet the course pre requisites.
I was hipoxyc trimix in OC and I was made first air diluent deco diver, I was allowed into helitrox/mix d gas only after 35 hours of air dil.
So TDI does not allow nn rebreather divers to start with helium. At least according to what I read here and what my TDI instructor told me ....
