I’m looking to buy some new measuring and calibration tools, starting with a Caliper. Is it better to go analog or digital? I’m a bit old school so I lean to the analog types. What do think?

I always kinda scoffed at using anything but a vernier caliper "You're just being lazy if you use a dial or digital caliper." was my thinking. Well, my wife wanted a digital caliper for her jewelry, so I bought her an inexpensive one from Harbor Freight for Christmas. She bought me a new planer for Christmas and in the testing out phase I thought I'd use my vernier caliper to check for snipe. As you can guess, using the vernier got old fast so I went into her room and grabbed the digital caliper. :o

As for dial or digital, kinda a wash, but I think I'm a convert and would go for digital.

For woodworking I like the analog better because the visual effect is easier to relate to. For electrical, I like the digital as it is more exact.


Try MSC for some good prices.

I have 3 of those cheapie HF digital calipers (all purchased on one of their sales!) and leave them at what I consider critical areas of the shop. In comparing all three, I only found a .001 difference in their readings. Most recently, invested in another inexpensive digital readout for my planer. Again, most accurate and really helps with efficiency. (IMHO :) ) I would go digital on more of my equipment were it affordable!:) :cool:

It doesn't matter to me as long as it measures in fractions of an inch and not hundreths of an inch. Its just easier for me to use without the conversion.

I've been using dial clipers for over 30 years and I have never had a battery die yet. :rolleyes:

Seriously, I do not like the “feel” of the digital ones.
The Brown & Sharp dial clipers have the best feel, IMHO.

It's purely a matter of personal preference. I have an analog caliper which I like, but my next one will probably be digital becasue there is no chance of misreading it.

Digital, digital, digital.

My Dad is the oldest of old school when it comes to mechanics, and even he is using digital calipers and micrometers.

I have both and perfer the digital...it is easy to read

digital is my preference, I also work in metric

Best bet is digital with auto on and auto off. The battery will last forever (practically). There are new versions that will withstand harsh environments such as cutting fluids. Very robust, shop dust is no issue. There is no rack and pinion mechanism as you will find in dial types. The r/p system is an achilles heel. Mitutoyo, Starret, and a few others have these in their lineup. They are very good.

I am a hard core machinist as well and run a hardinge lathe among other things. Make many of my own shaper cutters.

I have both. In fact, I will cut you a deal on my digital starrett caliper if you really want it. I think digital calipers are junk. I switched back to a starrett dial caliper which reads the last two figures on the dial. The first figure is read from the stem. Very easy to use. Very accurate. No batteries and poking buttons. Unless you need an SPC RS-232 port for your computer, the dial caliper is often the better choice.

I also have an extensive set of starett micrometers which read in 10ths! Had to special order these as the regular micrometers only read in thousandths. Even though the digital mike can support the 4th significant figure, its accuracy is in question.

So I would get the old fashioned stuff in analog. But I would also make sure I got starrett or brown & sharpe.

By the way, I have an ELO DRO on my shaper. That is Digital Read Out. This device was lifted from the metalworking industry and is dead on accurate and reliable. I think DROs are awsome and the ones I truely love are the Newalls made in England. For woodworking, the A50 looks pretty good. The rest of the linup is metalworking only. Check out www.newallusa.com.

My hang up with digital calipers is the frailty of the unit and the absence of an off button. I was using it heavily and replacing batteries every 4 to 6 months. Also, it would go out to lunch until the auto off kicked in and shut it off. When this happened, you can only wait until the auto off sequences. On power up, it IPLed correctly and life was good until the next out to lunch episode. So I just feel more comfortable with the dial indicator these days.

I have two calipers...a standard sliding unit (really nice) that was my ex's grandfathers and a dial caliper that displays in fractions as well as hundreths. I much prefer the latter in my shop...fractions work better for me right now. I even set the new readout on the planer to display in fractions!

Odd that no one has mentioned a key advantage of digital calipers - they can be zeroed anywhere along the bar. Sometimes you need to know the difference between two objects, not how large either is. Digital calipers also can be switched between imperial and metric. They've come way down in price. Dirt contamination isn't likely to be a problem if you use the case that comes with many of them. Toss in one of those tables printed on plastic that converts thousandths measurements into common fractions.

Dave,
I love it. I have always preferred a dial caliper, but you have given me a reason to again feed my tool addiction. Thanks so much!

I have many years behind me using vernier, dial and digital and I'd have to say my favorite is dial. A fading LCD on a digital is irritating and you don't find out the battery is dying until you are in the middle of a measurement.

Digital with "large number display". My eyes need all the help they can get. Also, the ability to use either metric or imperial is a bonus.

I've been using a dial for well over 30 years. I bought a stainless steel one some 26 years ago and it still serves me well.
