mastercraft digital caliper?

I have a $10 set I got from princess auto. a machist will tell you that owning cheap digital calipers is like having a fat ugly girlfriend : they are both lots of fun and willing to please - until your friends catch you with one. They are pleny accurate enough for reloading.
 
The cheap one i have are hard on batteries, my Mitutoyo will go several years on a battery. Your best bet is to learn how to read a vernier scale first.
 
I like my Mitutoyo dial caliper, as its fast to read and reliable. The motorcraft digitals are fast and easy to read, but I would not trust them for all purposes. None are meant for measurements closer than a couple of thou. I use the digital cautiously, wiping the face of the jaws, closing them, zeroing, then taking my measuement. I have an uneasy feeling about trusting them for anything too critical. The closing presure affects the measurements on mine. But opening them to the desired case length and locking the jaws should produce a good enough result for something like looking for long brass.
 
have one, got fed up with it always needing batteries. Eventually Ditched it and bought a Hornady DIAL caliper and couldnt be happier, never looked back...
 
I've got one for work where it needs to be accurate to .1 mm (.004"). It repeats time and time again to within .1mm which is good enough for my use (measuring brake parts for safety inspections). Being used for 1 minute at a time, I'd say 10 times per week, it'll go about 6 months to a battery.

Great Idea. The last batteries I bought for mine were expensive.

Also make sure to shut them off, after use. I don't think they do automatically if you leave them. Come up on sale once in a while, which is why I got mine. :) CT also puts their micrometers on sale periodically. Probably some snobs out there, but definitely a cut Princess Auto.
