never learned to use one, a couple of guys in high school did use them,
but I did all my maths in longhand and sine and cosine tables, the
electronic calculator only just started to appear, computers filled a
room and used punch cards.

the digital vernier is just so handy in the workshop I have three of
them, and dial vernier along with a slide scale vernier, couple of
micrometers and angle protractors all with slide scales, all have their
uses, but its the digital verniers that I use several times a day and
nearly every day.

This article casts some light:

Looks like many just turn the display off, which achieves little other
than to avoid the unknowing owner worrying about battery life.

I've had a 20 buck Aldi digital vernier for around 12 months and it's still
on it's original batteries. When they die, I'll happily shell out the 3
bucks for new ones.

It ain't a big deal.

I've got a Kinchrome digital vernier which is more than 5yrs old and its
still using the original battery so battery life isn't a big issue.
