Favorite DIGITAL Tire Pressure Gauge?
My old one died. Had pressure checked in one tire shop then got suspicious when I felt every damned road gravel chip in steering wheel. Next tire shop claimed Cuarenta y ocho libras 48 lbs. Bled press...

Mechanical gauges require no battery but are dependent upon a spring maintaining the same stiffness and the friction of a barrel moving in a tube remaining the same for years.
A good quality digital gauge is solid state with pressure force on a piezoelectric crystal causing a voltage proportional to the pressure. It likely will maintain its accuracy for a long time and measure more precisely.
Cheap dollar store batteries die quickly. Good ones are expensive in stores. But you can buy good brand ones on eBay for a dollar.
I carry a mechanical and a digital.
