IP54 Grade Digital Caliper, DCLR-1205 0-12" /300mm, Inch/Metric/Fractions Conversion, Stainless Steel, Large LCD Screen

Ive had these Clockwise 12 inch digitals for awhile now and they still calibrate true. But it does go thru batteries quickly, thou Im using cheapies

I have had several of what I would call “mid-grade” digital calipers from various sources. Most worked ok, to be honest, but longevity was the main issue. As I am older, I decided to give these a try for the larger numbers and especially the tenths in a smaller digit. I have checked against my Starret micrometers, and it seems to be very accurate. Also like the fit and finish. If these last more than a year (most of my others didn’t), they may be the best deal on Amazon. Probably will order another on as a back up.

This is a very nice digital calipers. It is accurate and the different units are very useful: I regularly use both the mm and inch scales and the fractional inch scale is great for measuring drill bits and other tool/shop/home items in the US. It gives the same values to within 0.001 inch as an old Brown & Sharpe physical inch micrometer that someone gave me. Other good features: easy to zero, easy to turn off, auto-off, nice case to protect it. The original battery died very quickly, but the 2nd one that was included has been going for months. This is a great tool and I consider this one of the best purchases I've made in the last year.

I'm not a professional machinist. I am a semi-talented amateur however. I own a linear caliper from Harbor Freight, and I occasionally use Mitutoyos at work. I bought this (8") to treat myselfThis makes the HF calipers look like toys. On the HF, I can close the jaws lightly, then roll the wheel hard and see 0.1mm of change. On this one, I see 0.01mm. This is slightly less smooth than the Mitutoyos at work (running the jaws in and out feels just slightly rough), but functionally it works just as well. Accuracy is fine on a couple of things I checked (within 0.02mm of the Mitutoyo), repeatability is excellent.These are also heavy. But I love the display - something you can read from across the room. Good clear font with good contrast too. It comes with Auto-on (move the jaws and it comes on) and Auto-off, features that a few calipers I looked at buying before this were missing.Roughly the same price as an equivalent Harbor Freight caliper, but twice the value.Roughly the same capabilities and accuracy of a Mitutoyo, but at 1/3 to 1/4 the price.I'm gonna dock it one star, but that's purely for not being quite as smooth as a Mitutoyo. Of course, I can buy three or four of these for the cost of one Mitutoyo.

exactly what I ordered as I expected it - Thanks!

These are great calipers. I think I have about 5 of them around the shop.

I like it. Feels precision. Easy to read and repeatable results. The meter consumes power even when off as it remembers its last position. I don't really need that feature and would prefer it saved power. I disconnect the battery when storing to save power. One year battery life sounds short.

I'm a journeyman machinist, retired, doing stuff part time. I ordered many different digital calipers, and like the large displays these have, even better than my mitutoyos. Be warned: I've returned several calipers that only have large fonts for the first or second digit, then the rest are small...this is confusing and negates the large font advantage. I also like the front-button controls, since they're visible next to the display, and I won't accidentally hit them, like some units with the buttons on the underside of the calipers. I also like the buttons that have one function: on/off, zero, inch/mm/fraction. This unit had a multi-function button for on/off and zero. Not a big deal but still not perfect for me. This does display fractions but not a big plus for me, and I wish they would round the fractions to 64ths of an inch, not 128ths. What value is knowing a part is 77/128" anyway? The battery compartment ease of access is a plus. Some units require a screwdriver to access the compartment, which is a pain, especially if you're in the middle of a job and don't have a tiny screwdriver handy. The mechanics are smooth, accurate, and have inside/outside measurements, depth, and step, and all seem to be accurate, although I'll calibrate the measurement I'm doing with precision calibration "donuts", or gauge blocks, if the measurement needs to be super accurate. The battery lasts a long time if you remember to shut it off after use, and a good tip is to lock the carriage when turning if off for the day, and storing it in a drawer, where it might be triggered on, if it's jarred with opening/shutting the drawer, or other action. If you're new to using calipers, practice your measurements on a calibrated material....dowel, gauge block, etc. Your hand strength on the carriage should become uniform, and should only take a light touch to get accurate results. Erratic, or too much pressure during measurements, especially round objects, will create errors. I could go on but hopefully there's some useful information here. I love these calipers. BTW, spend the money and get good quality, stainless units, not plastic, unless you're really strapped for cash. These will last years. "Buy the best you can afford and cry only once; buy inferior calipers and cry every time you try to use them." Nothing worse than cutting a dozen parts, then find they're scrap because the crappy calipers weren't accurate. These are very good calipers.
