Regulator technical question

[1011ster]

Hello again
A bit of a geeky question but that's me!
Going through all kinds of research trying to find a regulator (finally ordered a 42 proton metal/proton metal octopus), came across some techical data at the Mares site, giving pressure and work values for each reg. Can someone (Zack, Phil, anyone, Bueller), take a little bit of time explaining these values? I.e. is the inhale pressure the pressure you must create for the second stage to allow air in, or the pressure that the reg sends to your mouth? And so on.
Again dorky question, but I gots to know!
Thanks.

I believe that this link will give you much of the information regarding breathing effort, and how to interpret a breathing simulator graph.

Thanks for your help Greg, that article explained a lot. So if I read this right, the 42 Metal proton is the easiest breather in the Mares series, with 0.67J/l. That's not bad and it makes me happier I got it!
Thanks again!

Yes, it does have an excellent ANSTI simulator score. A person can't really tell the difference in the WOB (work of breathing) on a regulator until the difference is between 0.4-0.5 j/l of energy.

Enjoy that new regulator, you bought an excellent one!
