I would like to personally thank Phi Lee for being so smart as to catch
the "subtle" difference between 2 half turns and 1 full turn.  I realize
that
I as a mere mortal can not turn a valve behind my head a complete revolution
without dislocating my wrist.  Apparently he can.  Thank you for posting
yet another useful message in the never ending "concentrate on the
minutia instead of the content post" mentality.

Also, not related to Phi's post,  It seems to me that the how one would want
a manifold isolator positioned for mixing gas is COMPLETELY separate from
the
discussion of how you would want to position it for diving.  If you are not
intelligent to be able to position an isolator for mixing gas, you probably
shouldn't
be mixing in the first place!

Adrian,

Do you think it would work with 1 full turn, or must it be *exactly* 2 half
turns ?

    Well, i've been diving with the ISO two half turns , since having a twin
set!, and proberley 3/4 OF Europe dive's The BullShit Paranoia Way, I'm
Sorry that i've No Idea about Diving OH DEMI GOD OF THE UNDERWATER WORLD

      And what bullshit paranoia do you attribute the "two half turns "  to?
This is the kind of mindless crap that gets people killed. I will say right
here and now that you can come up with no reason to do something that stupid
that makes any sense what so ever. Give it a try.

        I have the ISO two half turn's on, and I think the key is to , Know
your kit inside out, I've sat in the dark , in full kit for over 30 hours
,every new bit of kit , i go through the same process, and Do know my
current config  Insideout , the wife finds this highly amusing if/when she
walks in . same goe's for inwater training dives .

          Just a quickie. I'm just about to buy my first twinset with a
manifold. I've dived twins before, independents because of fiscal reasons
(I'm a poor student!) What I need to know is this. Some of the people I have
talked to who dive manis only open their iso knob about 1/2 a turn, whilst
others open it all the way. Thinking about it I can see advantages and
disadvantages to both:

          All the way
          Adv:         No risk of turning wrong way

          Disadv:     May get stuck if turned on all way
                          Have to turn it 3 turns (or whatever)

          Part way
          Adv:        V fast way of isolating

          Disadv:    Can turn it the wrong way
                         Not having it open all the way may limit
equalisation across the manifold.

          Now any or all of this may be unmitigated rubbish, but it's just
what I was thinking about last night.

          Any comments/suggestions as to how best to do it?

          As this is my first post, go easy on me - I'm still learning!

          Many thanks,

          Chris
