Smith" <afn20573@fr*.uf*.ed*> Reply-To: <Pine.3.05a.9506191158.A39169-c100000@bi*.bi*.ha*.or*> The Wakulla Project book had an example of differential He loss, if memory serves. It seems that someone had a slight manifold leak which allowed He but not the other gases to leak out. This produced a tri-mix which was lower in He and proportionally higher in O2 and N2. Very bad news when diving to 250+ ft for extended periods. Close call. Double check those mixes like the man says... Paul Paul, that used to happen to me too. By the time I got out to the wrecks, the helium would be all gone and only the air was left - it was a real bitch. - George Irvine -- Send mail for the `techdiver' mailing list to `techdiver@terra.net'.
