The other day I had a Digital Caliper  read half of what the measurement was . So in my quest for knowledge ,I came  across this .

Character is doing the right thing when nobody is looking .   There are too many people who think that the only thing that!s right is to get by,and the only thing that's wrong is to get caught .

i have a pair similar to these, it gave me a couple of weird readings (said a 3/8"bolt was 1 1/2") changed the battery, it's matched my mechanical dial calipers again. maybe i should spring for a better pair?

I have this caliper for 9 - 10 years . Never gave me a false reading ,until last week .   I used a neodymium magnet to pull some bearings out of their housing .       Yes the magnet stuck to the caliper at one point .       From my search a magnet can fool with the micro computer in the caliper as well as a weak battery .
  As far as cheap versus expensive , the consensus is all have accuracy +, - 1 thousands   you pay for the fit and finish  .

I had a HF pair I gave my son-in-law,he reloads ammo.Then after I began servicing my reels & replacing bearings I saw the need to measure the unknown. I got a nicer $20 pair from Amazon,not necessarily more accurate but not as much plastic.
