NE Strokes like redundant air supply......tell >me what happens with out of air situation with an octopus???? twice as much >out of air??? BDI, you will note, never says DIR - he used the phrase "hogarthian inspired" which seems accurate. Still, one has to question whether a rig like this is a logical stepping stone to DIR, or blantant strokery. It has been said here many times, that DIR is a system, and that change one element and it may not any longer be DIR. Redundancy - clean, uncomplicated redundancy that doesn't increase task loading - is the at the core of the system, and the isolator manifold and long hose the key to that. This "hogarthian inspired" setup has neither long hose nor redundant air. Dive it without the wings, and there's no redundant buoyancy either. Nothing necessarily wrong with this - most rec diving is done without either - but giving as it does, an illusion of DIR without the substance, it could be argued that rigs like this, on OW divers, may be trivializing and diluting the DIR message. Jacket BC's are not inherently evil - as Jim recently pointed out, they are often preferable with a single tank. With an alu single, they are also much more likely to float a diver face up on the surface, a serious consideration, especially with OW's. -- Send mail for the `techdiver' mailing list to `techdiver@aquanaut.com'.
