<div>Alan, I see no reason why that would not work. Emile mentioned that the Mantis subs have a very clever water powered arm.</div><div>Hank</div><div><br></div>

Just wondering if people use / have an external valve to purge air / O2 from the <br clear="none">
system to enable the removal of the first stage yoke from the tank.<br clear="none">
With a dive set up you just press the second stage purge valve.<br clear="none">
