    Beside giving opportunity to have another gas Argon bottle gives ability to shutdown the line quickly if the inflator get stuck for any reason. In cold water it is a high risk. And with single tank you cannot really close the main valve to let it warm up.

    Actually, recent studies sponsored by the Office of Naval Research show a quite substantial (up to 32%) increase in insulation value when using argon over air:

    Rubicon Research Repository: Item 123456789/7962

    In water <50F, I certainly notice a difference between the two gases (using argon does require a separate bottle to pre-purge the suit of air; though I've only ever done 2-3 purges, not the 6 used in the above study).

    My recreational dives tend to be longer than my T1 dives, so in cold water (e.g. back in MA or up in MoCal) I'd prefer taking argon over air/nitrox even with a single cylinder.

    Ranier -- Thanks for the reference. This is one of those cases where the feeling certainly is that Argon makes a difference and, quite frankly, even if it is just a placebo effect, it still is an effect!
