iGAGING Absolute Origin 0-6" Digital Caliper, IP54 Stainless Steel, SPC/USB Output Port, Inch & Metric Modes, Case, Manual

The iGAGING Absolute Origin 0–6" Digital Caliper has quickly become one of my most reliable tools. The accuracy is spot‑on, and the measurements stay consistent thanks to the absolute origin feature — no constant zeroing like cheaper calipers. The stainless steel construction feels sturdy and smooth, and the slide action is precise without any wobble. The IP54 rating is a nice bonus, keeping dust and splashes from interfering with the electronics. I also love the SPC/USB output port, which makes it easy to log measurements directly into software when I’m working on detailed projects. Switching between inch, metric, and fractional modes is quick and intuitive. For anyone doing 3D printing, woodworking, machining, or detailed hobby work, this caliper is a fantastic upgrade. It’s accurate, durable, and feels like a professional‑grade tool at a great price. Now I just need to learn how to use my CAD software to be able to create more projects for me to 3D print. Made a few projects and this Caliper really helped making project simpler. And everything fit perfect because of the accurate measurements.

Perfect for any use around the house. It is simple to use and good quality.

I purchased this item thinking it would not be as good a quality as the product description said but I was wrong. The thing was well packaged and functions exactly as described. The plastic case is relatively sturdy and I expect it will protect it just fine. I have used it several times and checked it against other instrument readings and it is always dead on. I have only had it a few days, so not a lot of use yet, but I am very happy with it. For the price, I think it is a great tool. It is easy to hold, easy to use, easy to read, easy to zero. All of that is fine as long as the accuracy is there and it certainly seems to be there. It came with an extra battery which was a nice plus. I can't image it using a lot of power so I think one battery should last almost forever! BUT, when it goes out, I have a replacement (if it will still be good months down the road!). If it uses batteries faster than that, then I may have to amend this review. So, mark me down as very satisfied and pleased.

This is by farm the most-used tool on my workbench. I keep it next to my pencil and notebook and I have used it to measure, fit, and reverse-engineer all sorts of things (toys, electronics, 3d printed parts, replacement parts, etc.). I am definitely getting my money's worth out of it and it is 10x better than a ruler (I have those, too). The absolute origin feature is also great. This means I don't need to zero the caliper each time I use it. I did have to reset my absolute origin when I took it out of the box for the first time, but it has since stayed at true zero even after hundreds of measurements. I am docking one star because, in spite of its usefulness and accuracy, the caliper is not very precise. This is a big deal for a measuring tool! As you may recall from accuracy vs. precision, accuracy is hitting the bullseye, while precision is hitting the same spot consistently. I have trouble replicating measurements with this caliper depending on how I hold the part, how I hold the caliper, whether I close the probes using the gear or by sliding the probes, whether I use the tips or the inside of the probes, etc! The tool is rated accurate within .02mm but I often have variance of approximately +/-.1mm when performing repeated measurements, which seems to be caused by flexibility / tolerance between the probe and the slide, or flexibility of the metal itself. In spite of this I have still got a lot of use out of it, and overall measurement accuracy is pretty good (when measuring and printing or cutting parts to fit, for example, they fit). For the price and utility, though, this caliper has -- hands-down -- been the most worthwhile purchase for my workbench. I would buy it again in a heartbeat, though if I were doing serious work with this I would invest in one that is more precise. A quick note about USB: This caliper has a USB feature. I did not buy this caliper for the USB feature, but I noticed later that the USB connector cable (sold separately) is over $100! Bear that in mind if the USB feature is important to you.

There was a very comprehensive set of reviews written by someone else on the various price breaks/best caliper per group... and for the $30-50 this was the top ranker. I have worked manufacturing line jobs and had a digital caliper glued to my hand for the whole shift many times, and there are some things I look for when I buy a caliper. This one is a bit heavier than I expected. It is a little bit larger head, but it is solid. It came with an extra battery, and it's a fairly good feel and slide to it. One downside is the bar is just sort of marked by the ten millimeter groups, no scale where you could run an estimate manually if the battery was dead. Nothing to mark it off for though. It came with a little bit of oil to prevent corrosion on it (easy to wipe off) and a bit of paper between the jaws to protect them. The serial number was handwritten onto the accompanying paperwork including where calibration and accuracy checks were performed and handwritten the name of the inspector and date. (within 2.5 months of when it arrived in my hands). It was ready to go out of the case. Accuracy and repeatability, seems right on, even when I pulled the jaws to near max. I'd say I got very good value for my money; I will update if it warrants it. Overall, the other recommendation was spot on, and in this price range it's a very good tool, accurate and well made.

I have several of these in my garage by the lathe and in my reloading room. Good quality digital caliber, especially for the price. Will wirelessly connect to your computer for working in spreadsheets,etc.

Even though I just getting started in machining, I have a long history with metrology. I got these out of a desire to move to the digital age. LOL I have several pairs of calipers, from multiple brands. I have 3 Vernier calipers (1 Mitutoyo, 1 Aerospace, and 1 Mauser), 2 Dial Calipers (1 Aerospace and 1 Mitutoyo) and a couple of randoms in metric. First Impression and build quality: The first thing that strikes me is the gravity in this ting. You pick it up and you are holding a tool with heft. In my mind, that's a good thing. I have have held (and used) cheap, poorly made digital calipers. These aren't them. By a long shot. These feel good in the hand. The display is large and clear enough to read easily. Something that my failing eyes really appreciate. The edges along the scale are broken so it doesn't feel like you are going to get cut. My tastes would have like a tiny bit more, but if you want or need that kind of feel, there are "better' ones on the market where you pay for that sort of thing. Accuracy: Good enough for the girls I go out with. I measured them against a set of feeler gages, gage blocks and 1" through 5" standards. Without fail they measured dead nuts on, and always returned to zero. I was very impressed, as I figured I would eventually get a reading that was .0005" off at some point. Nope. The jaws are very precisely ground and I could find no passage of light between them along the entire length when they are closed. Remember, calipers are machinists approximators, if you have something that is critical, you need to mic it. Final thoughts: They aren't Mitutoyo's or Starrett's. If you want those, then spend 3x the price. You will get a somewhat nicer feeling tool but I don't think you will find anything more accurate though. I decided to save the difference and buy more tools to add to my collection. As a PS to iGaging and to other manufacturers. how about a led back lit LCD display with a rechargeable battery? That IMHO would be a nice upgrade for ageing eyes and would eliminate having to have the right battery on hand when it needs replacing.

Awesome! All that you actually need from a caliper.

Very high manufacturing quality, lot of extra-items provided (batteries, screws drivers, calibration certificate, etc...) Very satisfacted.

The movement is buttery smooth. Very accurate. Easy to read display. I recommend. M....

I have used many different makes of calipers and these are the best yet.

This is the first time I use a digital micrometer and it works as expected. Solid construction

I purchased this electronic caliper to take the measurements of one of my bass guitars so I could send them to a bass builder to have one of my other basses redone to the same specs. He wanted these measurements befor starting any work.
