I have two of these. Mitutoyo has a very strong reputation among professional machinists for accuracy and durability. This caliper is in an entirely different league from the more common copies that sell for a fraction of the price, several of which I've also had. It's worth every extra penny that you'll pay for it.

Digital calipers are under $10 on Amazon (but reliability may be "iffy"), or $20 for a much better one at Harbor Freight. The HF is a copy of the Mitutoyo Absolute Digimatic ($125). Very handy tools for a lot of things. Examples; nut width, string spacing, fret height and measuring the thickness of old credit cards to be used as gap gauges.

My 'toyo has well over a decade of shop use and still works great.

Old dial calipers. They still work are still accurate and I am comfortable with them, been with me about 30 years

I guess that the OP is commercial spam - don’t click on the link - but the topic has some interest. I have old micrometers and vernier callipers that do the job well enough, similar old tools can be had for very little of off eBay. Save your money, give an old tool a new home and don’t waste resources by unnecessarily buying new.

Brown and Sharpe 0-1" micrometer.

Honest to goodness, I think almost the next purchase after a basic toolkit and a level, for many people, ought to be a quality 6" caliper and a 0-1 micrometer, along with a diameter tape. I struggled along without good measurement tools for decades, but any task involving more than the very most basic measurement has become orders of magnitude easier once I purchased these basic tools for myself (I've been using precision measurement instruments professionally for 40+ years).

While I have a digital, this is my quick grab-it-and-measure tool. Its resolution of .001" is good enough. Shown in the picture is .051"

Hint: when your store a caliber or a micrometer, leave it open just a bit so the measurement surfaces won't corrode.
