After reading the comments, I bought a brand new Pittsburgh caliper last night to see if they're any different now. The new one is DREADFUL. It's nothing like the old one I showed in the video. It looks like it was ground by scraping it on a brick. Even after disassembling, cleaning, and deburring, it still doesn't slide smoothly and I can't get it to repeat consistently within .03mm. The fit on the beam is so bad that the inside jaws often get hooked on each other and they have to be separated to get it to open.

This and the battery life that people have mentioned. The other joy that you can get with current cheap import calipers is that they can miscount. So you're moving the jaw and it counts 1mm, 5mm 10mm, 87mm, 25mm. Unless you've seen it or it ends up with an obviously stupid number, your part is going to come out to the wrong dimension. You end up taking the measurement two or three times with a good zeroing between each. Being able to trust that what the decent caliper says is true (and repeatable) is worth the sanity conservation alone. Like you, my import calipers are reserved for scribing...only I use the decent ones to set the gap as the battery will always be dead. Incidentally, I found the IP67 Mitutoyo's (got them on a good sale from a reputable distributor) to be a much smoother slide than even the standard Absolute ones. Perhaps that was just luck or lapping - either by factory or use.

Go buy an igaging one! The real thing to investigate is that the igaging ones are likely capacitive (based on another KZreadr who reviewed their digital mill scales). The mill scales video comments triggered speculation that the capacitive might drift through time. However the incremental performance was exceptional for the price I wonder if the expensive calipers (mitutoyo etc) use glass scales? (Don't drop them?) That might be the real easy to cluster these things? However the igaging have super measuring electronics. Above average mechanicals (no gaps in the jaws). But seem priced in the cheapie category Hidden gem I feel.

I once worked for an automotive supplier that did just that even using a coordinate measuring machine showing parts to print tolerances when they were not.

Mitutoyo has/had a patent on a battery saving feature for calipers etc, so the batteries on Mitutoyo calipers last significantly longer than the cheapies. The battery saving feature alone to me makes the Mitutoyos always the best choice for calipers. Nothing sucks more than needing to use calipers and having dead or dying batteries. Also the accuracy will drop as the batteries die (but it's usually pretty obviously off). There are some solar powered ones out there now as well, not sure how they are. The accuracy of the scales is typically pretty similar among digital calipers as they're made via lithography and cheap to make accurately. Jaw fit/finish can differ, but accuracy is typically pretty similar among calipers. When in school for machining years ago, calipers were generally considered to be acceptable on ±0.005" tolerance parts. Anything tighter tolerance required micrometers or better. Not sure how much I agree with this, but I usually use it as a reference point if I'm questioning a measurement. Also, great videos! Super informative and interesting!

As you said: The battery drain is often a problem. I compared a cheap and a Mitutoyo once in detail. The cheap one drained 10 times the current than the Mitutoyo. And just for kicks: I turned off both and realized the cheap one didn't changed the current. It just turns off the display, that's all. The Mitutoyo dropped down to nearly nothing. About 200 times less the cheap one had. And another thing I noticed: The measurement consistency and stability. The cheap one is hopping around a lot on the last digit and repeated measurements often differ more or less a lot. The Mitutoyo shows very fast a bang on value without hopping around. I am happy with my Mitutoyo and the cheap ones I use for scraping stuff. So I do agree with you. You don't need the expansive once. But it's just a pleasure to work with. So, it depends...

Years ago I took my cheap Hornady set to a USAF lab I was in as a part of an inspection I was in charge of. After BSing with the airmen they checked the calipers on ceramic blocks and to everyone's amazement they passed. There is more user induced error than caliper error most of the time.

I’ve used calipers a long time and all you’ve said about pressure is worth paying attention to, especially if you are a reloader, which I am.

I use the HF digital micrometers for measuring bullet diameter after casting and sizing and they have a clutch on the thumb knob, I'm guessing so that the pressure is consistent. The HF calipers work great for reloading, but a few thousandths won't damage anything with the loads and seating/case lengths that I use. They do vary in quality though, so I have picked through them in the store. The 4" digital calipers were junk, and would jump all over at the store. I tried a hand full of them, so I used the 6" for my tool bag. If they start to mess up, they get trashed. HF has a dial caliper with 64ths that is nice for picking drill bits. I agree with him, that it all depends on what the job is, how critical it is, how you use them, and what makes you happy. Few HF tools meet my standards, but the calipers can be quite good and I don't feel bad for having multiples or if they get bumped or eventually fail.

@shanerussell5448

Actually the closer the bullet is to the lands the higher the pressure. Once you start seating deeper into the case the pressure will get lower. This is because gas can now flow around the bullet into the chamber, versus when the bullet is right at the lands it blocks off the gas flow around it, until the bullet releases. I used to think like you do, that a deeper seated bullet raised pressure, but unfortunately I found that is not true. I watched several videos, from much more skilled reloaders than I, people like Erik cortina. They explained it to me and I decided to try it for myself. I had some 165gr accubonds loaded right at jam, I was getting pressure signs way below max powder charge (mainly extractor marks and heavy/clicking bolt lift). Once I moved deeper into the case, the pressure signs started to decrease and I was able to raise my charge weight all the way to book max with no more pressure signs. I just thought I would tell you all of this, because I used to think as you do and had to learn on my own. Not trying to correct you or be a jerk, just wanted to pass on some real world useful information to a fellow reloaded. Hope this helps you in the future.

"Moore & Wright" are up there with Mitutoyo. I'm a (retired) Engineering Inspector, CMM & all that, Loads of Engineering companies have gone bust & are almost Giving mics away. Can even get say 0-6" Mics (One frame with different sticks) Don't be fooled by the resolution (the, half a thou' hype) with ANY digital calliper - what you are really paying for is the smooth, linear running & the parallelism of the Jaws.

I buy Mitutoyo for multiple reasons. At the price it is amazing we are able to get such a finely made tool. They set the bar to which others aspire and I like to support that. I don't ever have to wonder if I got an accurate measurement.

Way back in the day, AvE compared a cheap set of calipers to a set of mitutoyos, and he found that the cheap ones lost accuracy as the battery started to get low, while the real ones didn't.

I bought a pair of the dial version of them a few months ago. They let me go through them and pick the best ones(jaw tips), since there was nothing to tear open. After they were stoned, cleaned, and adjusted, they are great.

I've had (and have) several middle-priced calipers that have a battery life of less than 6 months if just left in the drawer. And at least one of them does indeed give squirrly readings when the battery is dying. But that is usually pretty obvious, and trivial to fix. Of more possible concern is really cheap calipers may not have completely parallel jaws, or the inside jaws may be off be a few thousandths from the outside jaws, or one of the depth ends may be off. Another form of this is "weak" jaws, where if you clamp down harder than you should you can easily spring the jaws (permanently) so that they are wider at the tip than the root. I guess you could probably do that to any calipers, but it is probably a little harder with the expensive ones. Or you are less likely to try to use them as pliers. :-) Of course, non-parallel jaws are trivial to check for. You didn't mention the "origin" button on the more expensive calipers. But if you looked under the skin on the cheap ones, I think you would find contacts for a 4th button. Not that that is very useful, since there is no physical button. Most of the cheap ones also have serial pins, possibly under a removable cover, for an external reading device. Not that I've ever seen anyone selling such a device, except for dedicated "scale" calipers. There is one other really cheap digital caliper that can be very useful in certain circumstances: plastic calipers! If you need to measure electrical things like battery terminal distances, these can be *very* useful. They are a little less accurate, since plastic is soft and expands with temperature. But over 6" they are still within 5 thousandths or so. But for $3-5 for a pair of these, and not having to worry about shorting out electrical connections and big sparks, they can be really great.

I bought a set of the plastic (may actually be fiber reinforced) calipers recommended on another channel. They are wonderful, smooth, accurate, and repeatable. On has to use some care not to force them closed because the jaws will flex more than steel. And they were really cheap.

James, very good advice you give here. For scribing bar stock I use a set of cheapo 0/6" callipers. For measuring functions I have a couple of In size brand callipers ,one set with carbide faced jaws, which are in the middle quality category. Another useful aid in achieving greater reading accuracy consistency is a thumb pressure regulating device. These are either a small spring and plunger or piston plunger over air inside a small dia cylinder. This device regulates the users thumb pressure to a more consistently repeatable level.

Great video and explain the feature very well. Thank you for including our Aventor caliper in your video comparison.

😍 Straight from the Mity' vs fake to this one. Liked this vid. Good, pragmatic comparison between price points. Totally agree with your points about having a tool that just works, is a pleasure to use and is trustworthy. I do more electronics then mechanical, but the same thing applies to multimeters. Using a cheap meter may be accurate enough, but having a good meter that I can trust without second guessing the results all the time is most definately worth the extra dosh.

Agreed. You can view having a nice tool as a simple luxury that some can afford, or you can view it as streamlining a process so using the tool doesn't interrupt the other things your brain is trying to do at the same time. If it's being used in a for-profit enterprise, it makes sense to spend a little more and remove friction. If it's a hobby, buy what makes you happy.

Thanks James. I always find it so satisfying to scribe something with my cheap calipers. I can quickly get a reasonably accurate mark and not fret about abusing my real measuring instruments. The cheap caliper is a tool - and I understand and use it as such. 👍👍😎👍👍

Great and useful video! A little trick I learned to get accurate readings with my dial callipers is to apply finger pressure to the jaws instead of the thumb wheel. I am a bit ham handed, and I can get readings a thou or two ubder size when using my thumb to check the callipers against a standard. By holding the callipers with my right hand, and using my left thumb and fore finger to apply light pressure to the jaws adjacent to the part, I get more reliable readings. This is especially useful when I have a small part to measure, or a part that has a small width shoulder to measure. This method also tends to hold the flats of the jaws parallel to the measured surface, eliminating error caused by a cocking angle.

Thank you for this video. It’s exceptionally useful. I have a physical disability and I’ve recently started 3D printing my own adaptive equipment. Things like small adaptors, mounts, handles etc. There’s a huge amount of utility in being able to attach thing A to thing B when they are different brands / sizes / painted / worn etc. I’ve found myself doing a lot of ‘relative’ dimensions based maths. Based on this video I’m going to invest in a set of nice callipers & a set of cheap ones. The nice set for my little workspace (corner of a bedroom!) and a cheap plastic set to live in my bag for quick and rough measuring when we’re out and about and trying stuff. Thanks again for an exceptionally helpful video!

I know it’s probably been shared many times, but my experience with cheap calipers has been synonymous with cheap multimeters. I’ve owned 3 pairs of calipers over the last 6 years, I went through two cheap ones in the first 3 years before stepping up to a Mitutoyo which has given me 3 years of trouble free service and it’s a joy to use every time you pick it up. Same thing with meters, I’ve owned about a dozen cheap meters over a 15 year period that all broke to some degree before spending the money on a Fluke. If I had to do it again I’d buy the expensive tool on the used market 9 times out of 10.

Thanks for the breakdown. Just picked up some Mitutoyos recently.

I've been an engineer with a cheap dial caliper since 1997 until 2023. I just received a Mitutoyo last Friday. I wonder if my engineering is going to get better. Actually I've kept my cheap dial caliper and even dropped it several times over the years. You just can't beat a mechanical dial caliper when trying to open it to an exact distance rather than measuring something like when he dialed 0.8000 ion this video. Since the caliper scale is thousandths of an inch, a cocky young engineer once put a little sticker with lines for one half millimeter. I've left it on there for ten years because it's been useful, lol. But apparently now I'm a Mitutoyo man now...

I tried 4 different brands of cheap calipers over the years. I always had the same problem with all of them. The display would start flashing soon after the new battery was installed, usually about a month. I gave up on them. Now I just buy the Mitutoyo brand. The wear and tear on my nerves just wasn't worth it for me.

Working in the trade for nearly 55 years, and seeing the younger guys gravitate to newer battery powered digital measuring tools, has taught me one thing.....the stuff doesn't last. We're still using measuring instruments (mostly Starrett) that were bought during the 1960's. Storing tools carefully, and routinely checking with standards will make them useful for years..

Amen to the durability of the old mechanical measuring devices. But they are only as good as their most recent calibration. When I helped the ISO guy at the plant he had to buy rulers, ordinary 18" metal rulers, that were calibrated to a standard. I was astounded to discover something like 10% of the rulers we bought (and we bought dozens) would not measure to the standard! The oldest device I used and still own is a caliper to measure paper thickness. It has a spring to make a standard force on the measured paper, and a 1/4" flat disc top and bottom to make the measurement on a flat section. It even comes in a fitted leather case, designed to keep in a watch pocket for quick access.

how on earth were they occasionally off a quarter of an inch? that is a massive amount to be off. I have not once ever seen a caliper off by that much, no matter what quality. even smashed and bent calipers could retain accuracy within a quarter of an inch. ffs a tape measure holds that accuracy, or a ruler. You do not even need a scale for that. Heck, even your finger bone holds that tolerance, you could get a better measurement with your fingerbone.

I have half a dozen of the cheap ones for the "laying around" jobs and in the normal toolboxes. I also have a Mitutoyo for machine work that I handle with much more care. No doubt they are nicer and just feel better in the hand, but the convenience of having casual ones around is quite useful. I have stoned the edges of one of the Pittsburgh to make it feel better and it works fine. I also have a plastic one made in Switzerland (a gift that I thought was a joke but turned out to be surprisingly handy). It stays in my computer bag for quick checks and makes it through airport x-rays without question. One of my newer Pittsburgh ones has auto-on and that's a nice feature. Thanks for the candid review and keep up the good work.

If the cheap one is sensitive enough to measure dust and needs to be re-zeroed every time it's turned on, I find this as a benefit as the sensitivity is that much greater than the expensive ones. I have used the Harbor Freight models for years with zero issues. Some even have the ABS function and even fractions built in. There are knockoff that are a fraction the price with the same functionality as the expensive models. It's sad that perception plays such a huge part in business. What I really want is one with a larger display for these old eyes!

I've been testing "male enlargening" products for a number of years now, and I got to say, I've been seeing far bigger gains with the Pittsburgh than the Mitutoyo.

I really like your perspective on this. People don't always realize that there is more than one way to look at the "best".

Common sense is so rare. Thank you for your application of clear common sense. I am retired and on a fixed income, so, I watch my expenses. My caliper is a dial type (inexpensive Wisdom SE). The slide and the dial must agree at 0. Over the years I must have dropped it because when zeroing the dial at 12 oçlock my slide is off .013 so I compensate for that by turning the dial where it reads .013 at 0. Since the zero is at the end of the scale I use the one inch mark to assure my caliper dial matches the slide. It works fine since I never measure anything that far down the scale. For instance I have no need to measure the thickness of a sheet of paper, but I do commonly measure things 1/4 inch or greater. Yes it does limit the calipers range a bit, but it is accurate where it counts. The drawback is my dial is canted clockwise a bit. Thanks for your video I have been wondering if I should buy a new caliper and what price range is best for me.

There is a brand you can find through Amazon called igaging. I own several of the cheaper shaped items you show in your video and the igaging ones.

I have been happy with IGauging stuff also.

I've actually been using the even cheaper harbor freight calipers, the composite plastic ones, and I absolutely love them. They are light and I have no worries about a drop or knock messing them up, and there are no sharp edges to catch on anything. The slide feel is easy but reliable and clean. (And I got them in black rather than their garish current color scheme). They hold their battery forever, unlike the $30 ones out there. As for zeroing, I always put them down with their jaws closed, and always turn them on before opening the jaws. This process (totally muscle memory at this point) keeps them zeroed and takes no cognitive load. And they're so cheap I never worry about damaging them in use. My nicer calipers stay in the box because I rarely "need" the other features and worry about tweaking or bending them. Whereas the light plastic feels like it'll be fine if I knock it off a table. The day I lose or break them, I'll actually be quite sad. I'm rather fond of them by this point.

Good video. One thing I missed was durability. Had my first Mitutoyo vernier caliper for 30 years before it disappeared. Dropped it a lot of times. But kept measuring as good as a vernier can. Now has another one, usually in my trouser pocket for most everyday measurements. Only take the digital Mitutoyo or micrometers out of the drawer when needed for more precise measures.

The biggest difference I have found is when the calipers get coolant spray or drips on them. I measure inside the vise sometimes to keep the setup, and the tools can drip on them (I have a Fanuc Robodrill with 14 tools above the part in some cases). Mitutoyo deals with this wet surface perfectly and work the same, but cheaper calipers jump around and don't measure well or sometimes at all.

Thank you James....it's good to see an honest appraisal of the callipers. For me it will be the cheaper end of the market although I would love the Mitutoyo brand...I just could not warrant the expense given the type of work I do. I have no need for micron level instruments and using a calliper as a marking gauge suits 99% of the work . If I need to replace the cheap ones every couple of years then so be it. The keyboard warriors need to spend more time making stuff than slagging someone off for using a method they don't approve of. Keep up the excellent work my friend.👍

Like all things, it just has to answer to your needs. Excellent no nonsense review !

Thanks for the comprehensive run down on the difference between cheap and expensive digital calipers.

A while back I took apart a number of these, and they are all identical inside. The operation principle is the same, and it relies on the accuracy of a traditionally etched PCB. The good news is that they are made such that only the long range accuracy is what matters, so it's fairly easy for even a cheap caliper to achieve the 30 micron rated tolerance. Personally, I use the cheap ones. But I also have used a bunch of Mitutoyo, and others. The best calipers by far are iGauging. They are less expensive than Mitutoyo, and I have found that they are more accurate than Mitutoyo as well. The best value I think are the Vinca brand. They feel great, cost only about $24. They do have an annoying flaw that they drain batteries even while turned off. But for shop use, that's fine. Maybe not for someone at home where they only get used once a week or so.

It's been my observation that more expensive does not always translate to better, so completely agree. Having said that, I think for dial (analog) calipers, price and quality do go hand in hand. I'm partial to the B&S dial calipers, they feel great right out of the box, never need to be zeroed out and never need batteries.

Late comment, but for a lot of small, sub 1.25" measurements, a snap-cal by Fowler is an absolute lifesaver.

Cheaper is ALWAYS better!

I always thought they were just cheap bottom of the barrel calipers. Not because they are bad in any way, I love them, they just don't look expensive. Who knew lol

I inherited a Mitutoyo analog dial caliper from my Father some years back and he'd owned it since the mid '70's. It's been very well cared for and it is still like new after almost 50 years. I tested it recently with my new set of grade B gauge blocks the wife gifted me (heh heh heh) and it is bang on. But more importantly, it is still a dream to use. The action is silky-smooth and the faces are ground absolutely flat. I love it. And yet, I find myself constantly reaching for the cheap $20 "Chungdong" Chinese made one which is exactly the same as the Harbour Freight one - and is available under several hundred BS brand names. Why? Because it has a ZERO function. This lets me forget about the mental math (and possibility of error) required when measuring offsets/differentials. I also bought a cheap FRACTIONAL IMPERIAL caliper that I use now just as often; and THAT one is a game changer. You need one even if you don't know you do. Here's the thing: when I want to measure a metal part with serious accuracy I reach for the Mitutoyo. Not because it is more ACCURATE but because it is way better for measuring such things. The flat-ground faces of the jaws and smoothness of action are unmatched and their hardness gives me greater confidence that I'm getting good measurements when I'm down to 1000's. So, like you said: the most important question is, "What's your use case?".

...it‘s called „confirmation bias“...

My Mitutoyo caliper was bought 21 years ago and used daily until I retired 4 years later. They are still used in my home shop but obviously not nearly as much. I also Have a pair of 12" Harbor Freight calipers that I bought while still working, because I had a few jobs that needed the extra length. I was surprised by the quality fit and finish on the HF one, and equally surprised by it's automatic off feature. The Mitutoyo caliper does not have auto off, and more than once I opened my tool box to start a work day and found the caliper still on. Not a biggie, but aggravating none the less for a forgetful guy. As you pointed out, the newer HF models may not be of the same quality as the older ones. Just for the record, I do love my Mitutoyo.

One of my favorite uses for my digital calipers after moving to Sweden from the US. Pushing the inch /mm button to see an instant conversion. 😊

Retired from a large areospace machine shop. When setting up a job we would order a gage for every setting we needed, height gage with =/- dims set, go-no go gages and so on, Always used the cheapest calipers I could find, kept at least 2 sets in my tool box.
