Minimum Experience for Rebreather Training

[BlueTrin]

IANTD do a MOD2+ down to 70m/230ft with min FO2 of 14%.

From what I've heard and experienced, MOD1 45m (helitrox) is considerably harder to do than MOD1 to 30m. It's unlikely that someone with minimum diving experience and no prior open circuit ANDP experience would be able to complete the MOD1 helitrox.

In any case you MUST practice doing the shallower levels to cement your new CCR skills in place before venturing deeper.

I think MOD1 helitrox has an additional day where you have to dive at 40m (aside form theory)

I am not aware of any other requirement.

In the U.K., it is hard to get because we don’t have an inland centre that can do 40m anymore and the weather being too unpredictable, I know only 1 instructor who would do U.K. Helitrox
