Autosupermart brings you the ultimate tire pressure gauge with high quality contruction and easy quick operation. This gauge holds nicely in your hands with a ribbed exterior and it reads from 0 to 60 psi in highly accurate increments of 0.01 decimal places. The large blue backlight display also shows a graph behind the digital readout. The quick release end means you don't have to press down hard and fumble to unscrew a typical hose end while air comes out. A flexible rubber hose makes it easy to get into small tight spaces. This unit comes with a storage pouch as well. It is powered by 3 - LR44 1.5V Lithium Batteries that are replaceable. We have tested them all, and this one is the best for your money, sure to last a lifetime.
