I guess it's universal we all have a routine know matter where we're from and we all ask, don't touch my gear
No it is not universal.
Less than a dozen members have expressed the "don't touch my gear" mantra and "I have a kitting up routine" in this thread; the obvious majority have remained silent.
I can reach my valve. I wear the same typical recreational rig for solo as for buddy dives. If there is a routine, it is the one taught in the pool sessions of OW training; put BC on tank, attach reg set to tank and BC, check air, don wet suit, anti fog mask, put on weight belt.
Is it really such a big deal if someone touches your gear, or even your valve? If a shut valve could kill you, should you be even buddy diving, much less solo diving?
