I find the optical comparator *VERY* useful
And at today's prices, downright cheap.
An example in the Utility Dept: Identifying 1.2-mm and 1.3-mm screws for eyeglasses. Plus others literally too numerous to mention.
On prices, I've had mine about 25 years or so, and I'm pretty sure I paid somewhat more for mine (something like $150). Which is an example of high-tech 'winning' yet again, I suppose.
Certain tools are very important to me, and a Pocket Optical Comparator is one I definitely recommend having.
