Folks,
Unfortunately, some of this commentary seems to be based upon partisan beliefs and not fact.
(1) The Europeans who use the "inverted cylinder set-up" (---Ed. note: In their view, we are the ones who use an inverted cylinder set-up.---) do NOT have any worse of a safety record than do our divers. The configuration, in an of itself, is no more or less dangerous than our own.
(2) If one thinks about it for a moment, if the diver posesses enough arm flexibility and joint articulation to reach an isolator valve behind the head, he can also reach one in his lower back reagion.
(3) A lot of the "valve down rigs" are not fitted with an isolator valve, for various reasons. In this case a "Slob Winder" is not required. (Ed. note: It is interesting to observe that the writer employing this phrase has purposefully chosen to use a phrase freighted with negative connotations.)
In any case, this discussion seems to have slipped into something similar to the Englishman and the American talking about language.
Cheers, lads!
