quote from rupert from the twin sets thread:

is this true? i was under the impression that even if you breathe a tank down to nothing there's still actually 8-10 bar in there that you can't get at.

(now trying to remember those diagrams of first stages that i actually managed to get my head round once!)

You can only breathe it down until it matches ambient pressure! I do not advise you to practise unless at the surface.
