A seller feedback score of only two,that may be a thing....

It's been suggested on a couple of other forums I'm on, technical ones, that there's a lot of fake Mitotuyo out there, and very convincing fakes at that.

Whether it's true or makes a difference I don't know.

I was suspicious that I thought they were fake - the paperwork behind is in Chinese.
On the prior ones, and some of the others, it is in Japanese ...

DIGITAL!!!!!!!!
FFS.
Do you need that level of accuracy or can't use proper ones?
Got a set of old school mituyo 'borrowed' from a now defunct engineering firm. Anything I do is only 2dp max so no need for owt fancy.
Found they go out of spec quickly when dropped off the machine beds several times!

Question still stands, do you need that level of accuracy?

The question may be better as "do you need that level of precision?', I wouldn't expect digital ones to be any more accurate.

Ooh, I love a precision / accuracy debate!

accuracy as describing a combination of both types of observational error above (random and systematic), so high accuracy requires both high precision and high trueness.

When I served my time in the 70s we used all non digital measuring gear. As a result I'm at home using the old stuff,but I can see how a different generation will find it easier and quicker reading a screen,rather than using the older method.

Tech moves on and if the operator can work to the level of tolerance required,it doesn't really matter how he/she gets there.

There are good bargains to be had buying old Moore & Wright stuff,so that's a plus.

Have a look at Cromwell tools, they have some cheaper options which are very good. Personally out of all of my calipers, the dial indicator is my fave, but they do have a pair of Moore and Wright digitals for around £30.
