The only 'solo skill' needed under such conditions is the ability to perform an unassisted ascent - because separation and failure to re-acquire your buddy would mean the dive was aborted.
DD ^ this is what I was getting at as far as breaking contact and 'de facto' self-reliant/solo. I suppose I can see how one can interpret my post as 'wing it and go solo when in no viz(extreme low viz)'. That certainly is not what I meant.
I understand what you meant... I just disagree in principle.
Bad viz...no viz... is no reason or excuse to abandon teamwork. Come on a wreck dive with me...and you'll see what I mean. If buddy contact is a priority...and effective procedures, planning and control are used... then there is simply no excuse. If I ever​ lose a buddy, I count it as a major failure for myself. No excuses...
Under hypothetical situations, an unassisted ascent, would be the only skill needed. However, a solo diver mentality accounts for hypothetical problems also... especially the likelihood of problems accumulating or occurring in series. Ascent alone in zero viz? Disorientation... issues with current... need to deploy a DSMB alone... etc etc etc
I see a lot more 'solo skills' applicable to any given scenario, that's all...
