I just heard on the UTD podcast (episode #29 around 57:20) that they advocate filling on right post and analyzing on left post. In my GUE fundies we filled and analyzed on the right post, and I believe that’s also in the GUE SOP.
The argument for analyzing on the left was catching filling mistakes (closed isolator etc.), but the way I see it, if the isolator is closed by mistake when filling, who cares what’s in the left tank, you’re going to be breathing off the right post! In any case you’re aborting the dive, or sharing gas while aborting if you open it under water. And of course you should check that the isolator is open both when analyzing and during the flow check before you start the dive.
So in case I somehow miss the closed isolator twice and start the dive, I would rather know what I’m breathing off the right post than having analyzed the left…
Am I missing anything here? Any UTD divers want to chime in and explain this to me?
