What tire pressure gauge do you use?
I understand the old slider type are a No No so I want to get a couple digital pressure gauges so I can compare for accuracy. Thanks.

I'm not really sure how a 'digital' gauge is any better than a slider. I mean, how do you know? What's the gold standard in gauges? Does a digital readout mean that the internal workings of the actual pressure sensing device are any better?
How do you know a "slider" is better or not?
Pretty much ALL gauges have some sort of error.
Mechanical gauges are not "linear" but if you look at the scale they "appear" to be since the hash marks are evenly spaced. That gauge might be dead on at half scale at say 50lbs but at 10 lbs or full scale could be off 20% or more..
Sliders, well I never had any luck with any $5 or $10 run of the mill cheap SQUARE PLASTIC types.. I could check the same tire 10 times in a row and get ZERO readings of the same pressure.. You have to spend quite a lot on a GOOD QUALITY BRASS slider in order to get consistent readings.. Then you have to be careful about getting dirt on the slider (get dirt in the slider and the accuracy goes out the window)..
I have two different brands digital gauges which I bought at Walmart, cost under $8 and you can take 10 readings in a row and get consistently the same readings within .5 lb.. They also seem to agree with my trucks TPMS so I am OK with the digitals..
