I'm not talking you gotta re-build your dub regs, or add another first stage to your deco reg, or dive your wacky Dive Rite uniwing with both your dubs and your single.
I'm asking how many Tech divers (presume doubles... RB is OK, too) have sitting in their dive locker a dusty single wing, a set of cam bands, and a complete reg set for a single cylinder - so you could (gawd) dive a single cylinder?
Yes, your wacky vacation Aqualung Yoke first stage with your crunchy neglected and Mares Micra or Ruby second stages count...
But you gotta have all of it. Single wing, cam bands (or BC, of course) and a full single regulator set. Ready to rock.
Backpack hippies need not reply....
I'm just curious. More and more of my buddies are going to doubles rigs and it seems less and less of them have a single rig that's ready to roll without retooling and urban renewal.
