I was never a big fan of digital tire pressure gauges until this one came out. The always seemed to be inaccurate and over priced for what we were doing.
But, this is what I use now every time I go to check tires.
Lonacre claims accuracy to .3 percent.
It features an automatic off, so when your in a rush and leave it on, it will shut off after a certain amount of time to save the battery.
It comes with an aluminum carrying case to protect it from getting damaged in the trailer.
It comes with an angled chuck for some of the more difficult valve stem configurations on steel wheel modifieds.
Digital pressure gauges have come along way from the crap they used to sell.
