Well, one reason is that the digital ones require batteries that they
use up even when turned off. Indeed, it appears the cheap Chinese ones
may do this in less than a year. So if one wants something that's
moderately accurate, for occasional use, the digital ones are not
necessarily the best option.

But I didn't actually set out to buy this. It was a cheap, and I thought
I'd have a use for it some time.

only if you need a small G-clamp (assuming it does have a slide lock)

You probably don't use your slide rule any more then ...

I have three of the cheaper verniers, plus one dial vernier and one digital
vernier
I prefer the digital vernier but as you say, the batteries could be a
hassle, so I use the dial vernier

I used to use one of these all the time, then I got a dial vernier, the
only downside to that was that swarf and filings would on occasions get
on the rack and make the pinion jump and would need to be reset, really
a pain around the lathes,

the digitals are so easy to use, easy to wipe clean, displays in metric
and inch thous, one I have even show fractions of an inch, good for when
you pick up a drill where the markings have worn off.

the new ones not only turn themselves off after a time, but they will
turn on as soon as you move the vernier.

the batteries last about 12 months or so regardless if the display is on
or not since the lcd displays pull so little power, if you are that
worried about it, just pull the battery out when you are not using the
vernier, usually the box the vernier comes in has a cut out in the foam
to place the battery out of harms way.

personally I cannot be bothered to use the old slide scale vernier even
though it is a well made one.
