The cheap digital ones seem to have the same accuracy as the digital ones costing £100 and that is achieved with one simple moving part.
Will the same accuracy be achieved with a cheap mechanical dial caliper with many more mechanical parts?
Yes, absolutely..
That's what I was thinking. I ended up buying a Vernier yesterday because it's simple (less to wear out), I know how to read it, & there's a Toolstation nearby.
I have a few of these.
They are light, accurate enough, not sharp, easy to put in a pocket when out shopping, don't require reading glasses, the battery lasts ok.
They do fall apart after a while, but at £6.00 I can live with that, like a cheap tape measure.
These don't need a battery
Yebbut, they need glasses.
My problem is a standrad verniers is too fine to read without my special modellers glasses. I sense an electronic one in my future...
But they do need a set of glasses...:-)
