    You can make your own vacuum gauge with a loop of clear plastic tubing and a ruler.

    Substitute the label "Gas" for "Regulator Second Stage Mouthpiece" and make a T piece to fit to your regulator with an opening to put in your mouth.

    Agreed and you can still use a sextant for navigation. :)

    What is the difference in Magnahelic gauge ranges? Why would one select one over another? I see 0-3 and a 5-0-5’s for example on Scuba Tool’s site.

    With a common cracking effort of 1-1.5", a 0-2" or 0-3" magnehelic puts your desired reading midscale.
    Since some out-of-tune regs will crack at 3" or higher, I think a 0-3" is better, while a 0-2" might allow slightly more precise readings.
    A 0-5" will keep you from pinning the gauge with a stiff reg, but may be harder to read in the desired 1" range.

    A -3"-0"-3" or -5"-0"-5" mag will allow you to read exhalation effort as well as cracking effort on the same gauge, at the cost of difficulty seeing precise values in the 1" range.

    Short answer, get a 0-3" magnehelic.

    If you want to go all in, here's a list of tools that will allow you to spend up to $600 or more to service multiple brands of regs.
    Or pick and choose for just the brand you own.

    Did you pay THAT much? :D :D :D I think I got two for $25 dollars one day. One was given away and the other mounted onto that plate. Yeah, most people don't realize that measuring the depth in a pot of water will give you the exact same reading. You don't have to worry about the rate of inhalation affecting it at all. If you buy one, 3 inches is perfect and anything over 5 inches makes it hard to be precise. Oh yeah, there's usually an inlet for measuring vacuum and one for pressure. Choose wisely. :D

    Or you can buy an U-tube differential manometer on Amazon for 15 USD:
