Nick, my mechanical colleagues at college despaired of teaching me how to read the vernier on a simple micrometer, so I regard the digital readout as the greatest boon.


I don't find verniers on micrometers or dials too bad, but a straight one one on a caliper or rule is tricky. But they're similar to log tables: I know(knew is probably more accurate) how to use them, but there are now better methods.

I buy stuff from Lydl too, not just Ebay  :y
but as with many things ,most is made in china / Taiwan etc ,imported,marked up .
plus ebay China stuff takes ages to get delivered ,though it is getting quicker recently.

I use the caliper to measure odd size pipe,bolts etc and the digital readout is great
 .(like ronnyd i struggle to see tiny scales )
I have recently invested in a couple of pairs of +3 reading glasses ,not to read with,just as hands free magnifying glasses to see fine detail,part numbers etc
again , another pound shop purchase  ;D

Strangely, this one purports to have been made in Der Faterland. :y

I have several measuring things that use those batteries, and the pound shop ones don't last very long. The off button on the caliper only switches the display off, the measuring part is still working so it's still using power.

AvE did a comparison of the quiescent current draw of set of Mitutoyo calipers vs. the Chinese specials - IIRC there is an order of magnitude of difference .. which is probably why the batteries are always dead in my off-brand long-scale verynearlies while they last forever in my branded short-scale verynearlies..

No, no, no. Egay is for the terminally lazy or terminally stupid.

I think the last update to the ultra crap Edge has buggered the spell checker, so renames to last word used.  PoS.
