Tire Gauge digital vs Mechanical

I wouldn't want to have to upkeep batteries. Mechanical for me. Consistency is key, not a half a psi.
Digital. However: I'm sure there are poor quality in both types.
I've had good luck with this one.

Here's what I use:
You can find it here or elsewhere on the net: Intercomp Tire Gauge
This gauge automatically compensates for ambient temperature and barometric pressure and is accurate to +0.1% of applied pressure. That means for a typical tire inflated to 35.00psi, the gauge reading would be accurate to within +0.04psi. The gauge reads in 0.01psi (hundredths) increments.
Not all digital gauges are as accurate as this one. Digital gauges are not necessarily any more accurate than analog gauges. Just because a digital display may be easier to read and may give the appearance of being more accurate, that is not necessarily the case.
Just a quick note on accuracy versus precision:
Accuracy means the gauge indicates a pressure that is an accurate representation of the true pressure in the tire.
Precision means the gauge indicates the same reading, when measured repeatedly, for the pressure in the tire.
A gauge can be very precise, that is it will read the same time after time when measuring a constant pressure, but not be accurate - i.e. the indicated pressure will not be an accurate pressure, but it will be repeatable.
When evaluating the purchase of a gauge, you need to decide if precision is enough for you, or if you need an accurate gauge.
If you are shooting to maintain the exact pressure recommended by the tire/vehicle manufacturer, then you need a gauge that provides good accuracy.
If you set your own tire pressures based on the "chalk test," visual observation of wear patterns, seat of the pants, or some other method, then a gauge with decent precision would suit you just fine.
Precision can generally be had for less money than accuracy - the choice is yours.

I have both Sears Digital and Mechanical gauges, they match one another within 1/2 to 1 PSI. I also have a Digital gauge(my BIL gave it to me) for about 10-12 years, the original battery is still working. All 3 gauges are matching within 1 PSI.
I got both free from Sears with free trial membership in Shop Your Way Reward, once a month they gave $5 to $10 credit to spend. Otherwise, either one was less than $6-7 on sale.

I prefer a mechanical gauge. I have the Intercomp 2.5 inch glow in the dark 0-60psi gauge.
I use a digital gauge. No real reason why, its just what I bought to replace an old mechanical gauge. I do prefer the digital gauge though, as stated before, the important thing is checking you tire pressure to begin with.

This is a great gauge although I went for the 4" for easier readability. Accurate to half a pound with a very convenient bleeder valve for dialing in just the right amount of pressure. Look no further.
