| Training standards - OC to CC Tmx
Here's a silly question. I'm sure that deep in the back of my mind the answer is hidden away, but I can't find it.
When an OC trimix diver crosses over to CC (as they all must - the pull of the silent side is strong) what level are they certified to? Back on air, or are they certified to use trimix as though they are OC?
And yes, I do understand the need to do lots of practice on a unit before you go deep, but do you really need another course? |
