You got it in one try.  Chuck first told me about them.  They're compact
enough to fit in even my smaller dry boxes, rugged enough to put in my dive
bag, easy to use and, once you learn to control the gas flow, as accurate as
pretty much anything I've used.  Our trip to Coz started me thinking about
one and a trip to a trusted fill station where 2 out of 2 analyzers
available refused to give consistent readings completed the process.  I
rechecked my gas using the analyzer at the dock before my dive trip and when
it showed a number sugnificantly different from what I'd asked for, I bought
the O2 Stick on the spot.  I probably could have gotten a better price if
I'd tried, but the time was right.
