Having just bought a rebreather I am in the process of looking
to do a training course.
I am trimix qualified on OC and it would seem that both IANTD
and PSAI can offer me a course that will allow me to use helium
in the mix to a depth of 48m and 45m respectfully.
TDI on the other hand can't offer me a course that allows the
use of helium just air to 45m.
I reckon I would be narked on an air dill at 45m and would much prefer
to have some helium in the mix I can't remember when I last dived air
as it's always nitrox or trimix.
My first choice of instructor teaches TDI and I would like to do the course
with him. Would anyone think that TDI may have this option on the cards
but not yet teaching it, they must be missing out ?
