[PSUBS-MAILIST] first stage regulator

[Stephen Fordyce via Personal_Submersibles]

Hi Alan,
Make sure you check the cylinder connection on the first stage if you start
to go down the official "nitrox version" path.  Being in NZ you are almost
certainly going to want a standard "DIN" connection.  There are some
European standards and conventions which see a different connection (M26)
used for high-oxygen diving mixes, which the official Apeks nitrox versions
are likely to be.

Ie. you probably want an O2-clean standard version rather than the nitrox
version of the DS4.  Worth double checking the cylinder connection before
purchasing.

Cheers,
Steve
