Just curious what everyone else uses. I have several gauges from a couple of stick gauges, to round analog gauges, to a 10 year old digital gauge that is one of the two primary gauges that I use. Both stick gauges seem to be the most inaccurate comparing to the others. The three round analog gauges are all within 1 to 2 lbs of each other. The digital is right there in the middle of the three, so the digital one and the middle analog gauge are the two that I use. The rest of them just sits in one of my tool box drawers in the garage. What do you use and find to be the most accurate?
