When I started scuba diving (in Britain) in the late 1960's, most regulators were twin-hose, and cylinders were slenderer, and most divers used twin sets, and what you call a `cheater bar' is what we called a manifold. All manifolds that I saw were like that. It was a hollow tube, with a regulator-type A-clamp on each end, and on its middle a connection like the top of a cylinder's pillar valve (but without on/off valve). If that is not called a manifold now, what is a manifold sensu strictu nowadays? Sorry to display my ignorance, but it is a long time since I last got near a twin set, in these days of big fat high-pressure single cylinders. Also in those days backpack shells were not used; the steel cylinders were strapped straight against the diver's back. How easy is it to get stab jackets that can fit twin cylinders?
