iGAGING Absolute Origin 0-6" Digital Caliper, IP54 Stainless Steel, SPC/USB Output Port, Fraction Reading, Depth Base, Case, Manual, Battery

I purchased this caliper and the compatible USB interface at the same time (see "iGaging SPC USB Cable for OriginCal 100-700 Series" for my very positive comments). The caliper itself arrives in a sturdy reusable storage device, with a battery installed & a spare battery in the case. The fit & finish of the caliper is above average, with no loose or poorly-fitted parts. Test measurements were accurate & exactly repeatable. If you've used this type of instrument before, you know that it's best when they don't do anything unique or creative. This caliper operates smoothly, the buttons all feel exactly alike, the display is clear & uniform. The model I purchased also included a base attachment that allows stable depth measurements. The instructions were easy to understand and completely explain the various features (purists may complain about the quality of the translation). A NIST-traceable calibration test certificate was also included, unusual for this price range. Besides the obvious quality, a key reason I selected this product is because all the reviews I've read state that the "average battery life" estimates are not hype. The problem with many similar products is that even when turned "off", they simply blank the display but are still consuming power, and may kill those tiny, expensive button cells in a week. The OriginCal series uses the much more common CR2032 coin cells, and other reviewers have reported shelf life of a year or more (the instructions list 2 years with typical usage). Of course actual battery life will depend most on how much you actually use the caliper. I did a ton of pre-purchase research because I was convinced I'd need to spend USD300-500 to get what I wanted. I even contacted the manufacturer by phone & they quickly transferred me to a person who could answer technical questions. So far, this product is everything I was hoping for & more.

Best caliper I've ever bought for this price and then some, hands down! You panty-waste talkers need to stop talking trash and RTFM. If you have a defective unit (and it happens) contact the seller or manufacturer and work it out. If you just can't read or fathom reading instructions, then send it back and keep using your thumbs, toes, arms and feet. I grew up in a shop environment and am very familiar with these types of tools. This caliper hands down is as accurate and precise as advertised. Mine in particular is highly accurate as I used my precision blocks (which are perfect btw) and could NOT find a single flaw or off measurement. As GadgetClass and David Andrews amongst others have noted, I also tested "numerous" items top to bottom in the jaw and the accuracy is stunningly accurate! At this price you can't buy another brand caliper this accurate for the money anywhere I know of. I had a small box of 6" calipers (some more expensive than this one) that I just tossed out because this iGaging caliper is that good! I will certainly be buying more iGaging brand items if this is any indication of the quality and craftsmanship they offer. Unless you work for NASA and the like, this caliper will accurately measure anything you need it too. And I'd bet NASA has a good number of projects this will suit just perfectly fine as well. Mine goes back to "0" "EVERY" TIME! I don't have to slam it or repeatedly go back and forth to get it too zero out. The locking thumb screw is a plus and holds the precise measurement in place very well. The fit and finish are top shelf! Depth gauge is just as accurate along with the perfectly machined depth gauge base. If you can read and understand what you have here and how to use it, you won't be disappointed. Highly recommended for home and business shops. The perfect all-around caliper for high quality general precision work. As Mikey said, "Try it! You'll like it!" ;-) Move over Mitutoyo!!! There's a new kid on the block, ...and he's giving you some stiff competition for the money!

What a search it has been, phew! I finally found a DIGITAL set of calipers at a reasonable price. The number of FAKE Mitutoyo calipers flooding Amazon and Ebay and FB Marketplace is dizzying and alarming. I found genuine Mitutoyos for $107 + shipping $15 but these were much less. So, why buy M when my need to measure is not scientific? I use these for DIY, jewelry, and fixing watches, sewing machines when I have to measure replacement parts. I love that I can switch from mm to decimal inches to fraction inches easily. Zero out at origin. There is also a stand you can set this upright, to lower the depth gauge and measure below the base. Very cool feature - check the sliding rod at the back. That is for depth gauge measuring. Comes in a nice box with new battery. Very very happy with this. My Nerdy neighbor has one too, and he recommended it. Buy with confidence.

I have been very been very happy with mine. I have 3 iGaging calipers that I keep in different places. The last model I got will show the measurement in fractions/decimal inches or decimal mm which I do like. If I were you I would get the version that does all 3. Definitely get the model that has absolute origin - all of mine do so I've never tried a caliper that doesn't but I would think that would be very annoying to have to zero it out each time. My buddy runs a high end calibration business (high end like he measures calibration of tools for a nuclear lab and a semiconductor company) and I brought them over to his calibration room and they were extremely accurate. He was impressed I was super happy. He had a Fowler caliper and Mitutoyo and as I recall the Mitutoyo bested the iGaging accuracy by some completely insignificant (for me and 99.99% of people) amount on one measure and the iGaging was exactly the same on several others. I bought the iGaging thinking this would be my cheap set that I would mostly use around the shop and that I would get a Mitutoyo as my precision set but after seeing the results I decided I had better things to spend $450 on so I never did buy a more expensive caliper. When you get down to that small of difference you are better to invest in some kind of way to take dust particles off the jaws (seriously - my friend did one measure and it was off a little more than it had been in another measure so he cleaned the jaws and bingo - it hit dead on). I wish they had an auto off feature. None of mine do. I can't tell if they have added this feature on the ones they are selling now. If they don't keep an extra battery at all times because you'll no doubt leave it on at some point and come back to a dead battery.

This is the version with the depth gauge base included and the fractional readout option in 1/128" increments. First the noticeable negatives. No automatic on and off so you need to remember to turn it off. Much higher power drain than the current IP67 Mitutoyo as this claims 2 years from a CR2032 battery while the Mitutoyo is claiming 5 year life from a SR44 silver oxide battery of 1/2 the capacity. Basically the Mitutoyo battery life is close to listed shelf life of the battery. You cannot get much lower power draw than that. Finish on the inside jaws is not as smooth as on the Mitutoyo, felt when measuring inside a very smooth wall hole. No burrs actually noted though. Positives are that it is the least expensive caliper I know of that comes with a calibration certificate and includes the electronics for SPC data feed to a computer, though additional optional accessories are needed for that, and they cost more than the caliper! Inside measurement matches the Mitutoyo and outside is dead on checked with a micrometer zeroing rod gauge. Length of a 1.975" long by 1.25" diameter turned bronze rod agreed when measured with the outside measuring jaws and the step measurement. I note that the step measurement is the one measurement option not listed or checked on the calibration certificate. Overall a good medium grade caliper for the home hobbyist machinist that comes with a calibration certificate. Not quite in the Mitutoyo IP67 caliper class but if you are doing true precision measurements then you need to be using a good micrometer.

More accurate than my ole beat up ip67 mitutoyo

This is way nicer than my cheap chinesium "performance tools" digital electronic caliper from O'Reilly's autoparts store. Those calipers seems to be generic with whomever company name is branded on it. The iGaging by far has a better fit and finish and glides super smoothly vs the other caliper, which stutters as it slides. The package contents were much better too. Performance Tool re-branded had just instructions and batteries. And the tool would bounce around in the case as it is loosely fit in there. The absolute origin w/fractiosn is held down nicely, with plenty of cushion to keep it from being knocked around. It came well bagged, with oil and paper wrapped around it to keep it from rusting. You're also greeted with a certificate of authenticity, and signed paperwork by whomever the factory worker was for calibration! And its *hand* signed. Very accurate, no wavering. Numbers are big and clear, and its easy to dial into thousandth of a mm (i couldnt do that with thte other tool as it was too stiff, so sometimes i would overshoot it). My only one minor gripe is that the lower lip of the caliper that is attached to the digital scale is somewhat magnetized. I dunno if this is a issue with digital calipers as my other one is magnetized too. I'll eventually demagnetize it but dunno if it will come back cuz i demagnetized my other caliper only to have it get magnetized again. Overall I am very happy with this device. Sadly i would have gotten a mitutoyo, but the amount of knockoffs everywhere kind of pushed me to pick this up. Glad i did. I own a few other iGaging products and they've all been awesome.

I just got the 0-6" w/Fractions and depth gauge attachment caliper. I am VERY happy with what I received! I loosened up the locking nut, and this is a buttery smooth sliding unit. No need to clean and lube out of the box (I will still clean it and lube it later, just because). Wiped the faces off, closed it up, turned it on, it was already set to zero. Got out some known precision ground shank tools (don't have gauge blocks, yet) and this hit the mark EXACTLY on every shank, every time. Far better than any of my other calipers I have (mainly cheap sub $20 Chinese calipers). Visual inspection the mating surfaces showed NO gaps what-so-ever! Everything is ground properly. All the non-critical edges have been knocked down so they won't cut you (unlike the cheaper calipers out there where you have to do it yourself). I did have to read the manual just to figure out how to reset the absolute zero (I have a feeling that it will be needed later in it's life). The fractional display is a bit funky and small, but I will adapt. I know most mashiniest won't use the fractional setting, but it is nice for those of us who have difficulties with fractions (even though there is a table of fractions to decimal on the back). I wonder if they could do some sort of button combination so you could set it to maybe just 16th's, 32nd's, 64th's, or back to 128th's display for those who need just quick dimensions. The depth gauge attachement is a very nice feature to have for those of us that haven't gotten around to getting a proper depth mic. It's a lot easer to check depth's with it now. I was alway frustated with trying to check the depth of something without having the attachment and trying to keep things perpendicular. The one thing I would like to have seen, with the case, a small circle cut out for the extra battery. Otherwise, I'm not sure where to put the extra battery so I won't loose it. I might cut out a circle later.

No need to spend big bucks, accurate with long battery life. Best feature is inch fractions along with decimal inch and mm. Polishing and finish excellent.

LO COMPRÉ PARA USO LIGERO EN CASA Y LA VERDAD ME HA FUNCIONADO PERFECTAMENTE, SE VE QUE ES DE CALIDAD. LO RECOMIENDO.

Was looking for an upgrade to my cheap caliper, this one is great compared to the cheap alternatives. Accurate and well built...

Se utilizó para medir 45 piezas en primera instancia, de cada una se tomaron 32 medidas, al final, se puede decir que es una buena herramienta, hay que tener cuidado, si se usa con las manos húmedas o una gota cae en el riel, dará mal la lectura hasta que este se seque por completo, de resto ha cumplido con todo lo que promete, incluye batería.

So glad I purchased this caliper. Very accurate and the error rate when adjusting or moving the slide rarely happens as compared to my cheap older calipers that happen all the time and that are now in the recycling bin. Its a keeper. Next purchase from IGaging is a micrometer.
