Spurred on by a recent boat trip where a geezer was wearing an unbelievably complex twinset rig with four first stages, a ponied 7 litre deco tin and a slob-knob, not to mention all the dangly gauges... What would a DIR-inspired twindies config look like? (Twindies = twin independent cylinders) Yes, I know there's no such thing, but just as an exercise in WTF. Kind of thinking the sort of thing you could take to some far-off place where there's no manifolded twinsets, but there is low-pressure gas and a lot of other novice divers around, so you take two tins, strap them together, then see what happens. The closest I can think of would be like a Sidemount config, where there's a bungeed single short hose, a long hose and two gauges. As they're singles, you'd end up with one 1st stage sticking "out" (the LHS) as the tin would be twisted around so you could manipulate the knob. There would be two SPGs with the RH one clipped to an "additional" RH waist D-ring. You'd use this in a similar way as per sidemount, breathing 60 bar(ish)/side. A donate is with the long hose, which would be clipped on the RH chest D-ring when not in use. Anyone tried a mongrel config like this? Any links to a suitable "Twin Tank Adapter" that would fit a backplate? What other alternatives would there be "when diving abroad". Sidemount's an option, but not really if they're the horrid fat tins.
