In my team, mostly rEvo divers, we have determined that removing the O2 reg cap and plug the orifice will be the approach we take for dives we plan to do over the next 12 months in the 120-150m range diving the unit in ECCR mode, seems the simplest approach to us.
Are you going to do that immediately and dive them that way for all your dives between now and the end of your 12 month planned period?
