I know Paul - rEvo's Daddy has done at least 121m on one.
with an IP of 11 bar, and some restrictions, the rEvo supplies oxigen up to 105 meter easely
why 80m: better not to dive on the limit of a unit, so indeed some kind of liability
the scrubber is not the problem for a higher depth
I know some people dive the rEvo with an 0.0030 orifice, and an IP of 14.5 bar... so this keeps giving oxigen up to 135/140 m...
for testing, (AND ONLY FOR TESTING!!!) so we do not advise to do it, with the 32 beta units over 300 dives were done below 80m
you can do it different ways: eigther pumping up the IP a bit, even with a 0.0035 orifice, the flow will be a bit high during ascent, but once on bottom and during descend you need more oxigen, so that is not a problem
you can also pump up your PPO2 when arrived at 100m, (say to a max of 1.6) then do your dive to 120, say for 10 minutes, and come up to 100m where again you can pump up your PO2 to normal (1.3 or less)
during those 10 minutes, your PO2 will not fall dangerously,... and if it would be the case, you can always take some dil to increase your PPO2 again..
otherwise a separate small ox tank with a man add button, and a standard first stage on it: the cmf will not work anymore, but you can add manually..
see, if you know how to dive a mCCR, not such a big deal... BUT DON'T DO THIS YOURSELF, WE ONLY DID IT FOR TESTING !!!!!!
