I just had a chance to try out your Jayco 0-100psi ElitePro tire gauge (recently back from a trip) and it was amazing. I immediately liked the look, weight and feel of a purely mechanical (no batteries required!) gauge. Used it on two cars with totally satisfactory results. Usually I had to play around with my digital pressure gauge to get a good seal on the tire stem (and still get some air pressure down), inflate the tire, take a reading, deflate, take another reading, and repeat if necessary. With your Jayco, you need to take measurements, inflate the tire, deflate to the desired pressure, and the job is done. Accuracy seems on par with my digital pressure gauge, but I don't have a pressure standard to measure it. In order of preferred features, I would rank them as follows: (1) exhaust/return valve, (2) the ability of the chuck to press lightly against the shank (important!), (3) the ability to pivot around the Nodes improve positioning and (4) the large 2-inch dial. The rubberized sensor protection was also a nice touch. I would buy this device again.
