Even if the diver with the spg were to have prior notice of failure of a gas supply he would still only have the same options as the nospg diver if gear configoration were the same, ie same gas supply options ie. he either has no breathable gas for deco or he has (it may be a backup of the gas that failed or it may be some other substitute, or it may be nothing but H2O). If the decrease was relatively sudden eg. reg failure, then both divers would only have relatively little and the same warning if any at all. Either way both divers are now faced with a lack of supply and face the same problems. So why, if everything is relatively the same, introduce by way of an spg an extra chance for failure? eg. o ring, hose failure on this addition. Surely it's not just to have that extra piece of teckie equipment that everyone else has down at the shop/boat. Am I right George? and where's my free tape? Scott
