Hi,

I'm not really familiar with the ANDI system. But logically speaking, I think that all CCR divers should be able to purchase and use Helium with their certificates in order to minimize the narcosis effect. Unfortunately, with MOD 1 it can't be done so far, that's why changing the standards of the first course to include an introduction for Helium is important.

Best Regards. Wael

Hi Wael,

Just to clarify - it can be done with IANTD Mod 1 if you do Advanced Rec Trimix at the same time. I know it's an additional cert, but it does mean a Mod 1 diver can dive mix in accordance with their certification (Phil carefully sidesteps the use of the word 'legally'

) which is your objective.

Cheers,
