    Hey everybody,
    Just wondering what IP most people have their Scubapro MK 25's set at.
    I read where Scubapro says 125 psi to 145 psi.
    Thanks so much.

    I shoot for 135-140. There is a chart in the little book that comes with a new reg, and SP recommends 133-142 psi

    Thanks so much. I've ordered the materials to make my own intermediate pressure gauge. Just wanting to check and see what my wife and mines MK 25's are set at.

    125 on mine, but it's to run with Poseidon second stages. Doesn't really matter what the IP is though so long as it is stable and your second stages are tuned to it

    This 125-145 is also the range for the Atomic regulators, which shouldn't come too much as a surprise. Why do these two manufacturers recommend this range? Does performance suffer at lower ranges? Does the regulator incur additional wear at higher pressure?

    I don't think I noticed any performance difference from the lower to higher end of the range spectrum. However, I do notice it when the second stages aren't properly adjusted.

    @Ouvea it's the range for most regulators. It's harder to get IP exact on piston regs in general vs. diaphragms *MK25 as an exception due to the screw*, so they need a decent range for where it is going to end up due to spring wear and what not. The second stages, especially the balanced ones are really forgiving to IP as long as they are tuned properly
