I've had a supposedly pretty good Accu-Gauge dial type tire gauge for a couple years. I've noticed that it no longer resets all the way to zero and back-to-back readings differ by 2-3 psi. I read some good reviews of the Roadgear Hi-Tec Digital Tire Gauge. I ordered one last week and have tried it out on several different tires. The consistency of back-to back readings is perfect. It has a digital display and also 'talks' to tell you the reading. It reads in .5 psi increments. Back-to-back readings are identical and it takes about three readings for the tire pressure to drop .5 psi. You then get about three identical readings until it drops another .5 psi. The readings are consistently 2-5 psi lower than my Accu-Gauge. Their website claims plus or minus 1% accuracy but I can't understand that since it reads in .5 psi increments. That would mean it can only be within 1% if the pressure is 50 psi or higher. The consistency is so much better that I have more confidence in its accuracy. It has a replaceable battery and a five year warranty. It is also small enough that it can be easily carried in a tank bag or even underseat storage. So far I am very pleased with this gauge.
