G'Day, Mate!  I'm always in awe of your posts - and anyway, isn't there
something about he who is without sin casting the first stone?  :-)

But you did raise an interesting point with regard to checking for CO.  It
used to be taught - and was common practice - to sniff the air after a fill,
(I know that CO is odourless, but if there were obvious traces of fumes or
oil vapours then the chances were that CO was also present), something that
rarely seems to be done now.  Apart from that, I've certainly never given
any thought to using a CO analyser - even if I could find a dive operator
who has one!  :-)
