I used an old tire pressure gauge. You know the ones you've been using for years. The old meter was good for quick readings, but now that I'm off-road I need something that's more accurate, easy to use and (more importantly) easy to see. The dual air chuck makes it convenient to read the pressure in my rear tires as the gauge stays on the detected pressure until you deflate it, making it handy when cruising on anything other than a nice flat road. It glows in the dark (I tested it) but I don't think I'll be playing around with my tires off-road and at night without an additional light source. I would definitely buy it again if something happened to it, which I don't think is too likely as it's solidly built.
