Aah. Its a terminology thing. You mean air
to 170 with Nx deco. I've seen people swim
into walls on air at 170 ft. Trimix is useful at
that depth if you're doing anything more than
cruising and looking. Doesn't change the deco much
either. And it doesn't hammer your body.
For training have a look at ANDI. It doesn't have the
interminable levels (just one more course and you're
nearly there) like the other organisations. Just
Intro Nx, Technical Nx, Extended Range, and Trimix.
The standards and procedures are written locally to
comply with local conditions and OHS regulations. At
least they are in Aus. Maybe its the same in Canada.
I like ANDI for the refreshing lack of bullshit. I think
they must keep Satterfield confined to the US.

named after a Saint.
