    How common is it for people to use first and second stages from different manufacturers?

    fwiw, I actually from time to time did cursory internet searches to see if any accident has ever been traced to "mixed" reg setups. Never found one as of yet...

    How common is it for people to use first and second stages from different manufacturers?

    Gradient factors - deep stops thread in DIR forum

    Hi, I think this depends quite on the dive, no? Now, sitting in front of a computer and just having the numbers to go by, of course most of us will say "34 minutes, as the risk is lower when not pushing it!". But I also have to think this logic through. The risk will go to zero for a bottom...
