Yup! If your reg tester is being used to test recharge and such, then get a good quality air gauge. The older style Ashcroft gauges that were used on Air America systems were pretty good without being expensive. As long as you use the same gauge for everything, you are fine if it isnt 100% lab grade accurate. Its repeatability that is more important in most cases.
