Slime 5012 My PSI Digital Gauge is handy and accurate to within 1.0 PSI. It includes a flashlight tip that allows you to quickly find the valve no matter the lighting, an easy-to-read digital display, and a reset button to help take multiple tire measurements quickly. Unlike other gauges, this gauge has a "My PSI" feature, allowing you to set your own PSI. It clips to the visor, so you always know where it is, and comes with a 2 year warranty.
