Digit Micrometers

Anyone using them? I have one pair of digital micrometers and I never trust them, I spend to much time checking them to make certain I didn't accidentally bump the zero button.
I get along fine with the standard ratchet stop Mitutoyo micrometers that I have but I keep thinking about trying one of Mitutoyos digit mics.
If any of the career machinists have an opinion of them I'd like to hear it.
 
I've also used a couple of different digital calipers. Being "old" school I have a hard time trusting them. That said, I have never found one to be off
when I check the measurements against a Starrett mechanical micrometer.
I guess it is a leap of faith for older people (myself) to trust electronics. The best part of digital micrometers is you do not have to do a conversion to get
millimeters.
 
I use some digital calipers, I slide the blades closed and check to insure they read zero ever time I pick them up. It only takes a second to glance at it and be certain. I can't do that every time when I'm using a 1"-2" outside mic or a depth mic.
 
Jay, by digit do you mean the ones with the LED display or the kind that has the rotating tumbler numbers?

I have, but never use the ones that require batteries because the battery is dead most times/ Old school for me. American made, Starrett, Lufkin, Tumco, ot Brown & Sharp.

Jay,

I have a very nice 0-1 Starret digital mic that I never use...because EVERY time I pick the freaking thing up, the battery is dead! And I have a helluva time finding the right replacement battery locally. So I stick to the old school, mechanical type mics.

Ironically, my calipers are Mitutoyo digitals, and the battery in those things last forever! Love those things!

I use the Mit digital calipers and micrometers but use the silver oxide batteries in them. Use them daily and change batteries about 1 or 2 times a year.
 
I was concerned when I started this thread there might be some cornfusion over the words digit and digital.
I don't like digital. Don't want batteries. I want a couple more micrometers 0-1&1-2 outside and a depth mic, just have tools at each machine. I always thought the little rotating mechanical digit mics looked like junk. I have yet to see one advertised as coolant proof but all the quality tool makers offer them so maybe they are good trouble free tools.
I have my days when I read a mic and think, did I read that right? I've remeasured several times and still wondered how the hell to did I come up with that measurement??
 
Glad I had the capacity to know something wasn't right and took the time to recheck the measurement.

IMO, use mechanical micrometers or for sliding calipers use dial type or vernier. As to getting repeat measurements it is all about "feel".

I use the Mit. scrolling digit depth mic. Love it. It's reliable and does prevent those occasional 'transposed' numbers.
