They are all far more accurate than the manual type. I keep one in both cars with an electric compressor at all times because I am a bit anal about my tyre pressures.
In that case I must be totally anal
In the drivers door stowage compartment I've one of those digital tyre gauges that you can not only check your tyre pressures with. But you can also smash your windscreen or side windows with it. And last but not least you can also cut yourself free from your seat belt with it. I also carry a two piston manual tyre pressure pump.
A case of overkill I can hear some people musing.....but let me tell you, over a period of less than two years there were three accidents on a stretch of road less than two miles from where I live. In two of those accidents they were single car accidents [ no other cars involved] In both these cases the cars left the road and landed in the adjacent canal. Resulting in both occupants of one car [ landed on its roof in the canal ] being unable to get out of the car, and subsequently drowning. In the other accident, one occupant managed to escape, one was recovered dead from the vehicle, and one was rescued from the car but died later from his injuries.
Oh and I've have one of those, plug into the cig lighter compressors die on me, hence back to relying on a manual one stowed away in the boot.................along with a fire extinguisher, two high visability jackets, a battery / alternator tester [bought at Aldi]. And a handy little tool kit in a zip up canvas type carry case bought for little money from either Netto or Aldi, resplendent with hammer, socket set, pliers, wire cutters, Stanley type knife, screw drivers, tape measure ...............in fact I used the same tool kit to put up a couple of candelabra type light fittings for the wife's aunt a couple of weeks back..........saved me a 34 mile round trip home to get my proper tool kit.
When you get to my age, most of you young bucks will have learnt the "real life lesson" that it takes less effort to be prepared for the unexpected , than the effort needed to be put in due to not being prepared for the unexpected.
