5.0 out of 5 stars Decent and very sensitive precision calipers

I had misplaced the plastic one bought for such work and so I second guessed myself and tried to measure a m.2 stand off on a powered off motherboard yet got a few errant sparks...looks liks the capacitors need alot longer to drain completely than a minute or so. The plastic one bought for stuff like this is throwing out a random loop of measurements.... had a look and that's been de-listed by Bolo. Time will tell if these precision calipers do the same.

This was bought as a gift for her birthday she was very pleased with it

4.0 out of 5 stars Not bad.

These are a reasonably good pair of callipers but they are very "no frills" & not entirely accurate, they have to be reset after each and every use. But cheap & cheerful enough to do the job required.

5.0 out of 5 stars Calliper is spelt with 2 'L's in the UK.

It is nicely engineered and feels right in the hand. Slightly ‘left hand’ heavy but acceptably so.OUTSIDE MEASURING JAWS: On holding it up the light, I can see that the machining is perfect. The gap, when virtually closed is absolutely even.INSIDE MEASURING JAWS: This is always more difficult to check because you need to look through the gap at a slight angle. It does however appear that the gap is not perfectly even. It is less than a thousandth of an inch out, by my eye-ball, and perfectly acceptable for my needs. There is a very slight roughness to the measuring surface which probably accounts for this. The 'error' will soon be nullified by normal wear and tear, so it really is not of significance.STEP MEASURING SURFACES: The calliper stands on end absolutely square - so the step surfaces are precisely made.DEPTH MEASUREMENT: Absolutely flush with the jaws held closed - just as they should be. The slider is slightly wobbly in the body but that does not affect the accuracy. Better that way that stiff.IN USE: The jaws can be held in place firmly with the thumb on the bulge under the display. Ergonomically, it is just right. The fine adjustment wheel is indeed a proper working wheel and not just a dummy plonked on there to make it look good. The locking screw works easily without having to apply too much pressure. Full marks then to Preciva for the design and engineering.THE LCD DISPLAY: It’s big and clear but it does not work well in cold weather. Anyone expecting to regularly work in the cold would be better off with a Vernier calliper or a Dial calliper. The manual says 5°C to 40°C operating temperature and it was less than that when it was delivered so, fair enough, it didn’t work properly.Whether you turn it off manually of leave it to turn itself off, it turns itself on again as soon as you move the jaws - which makes the on/off switch almost redundant. If you are travelling with one of these it may be a good idea to lock it with the top screw to stop it turning itself on all the time and flattening the battery. Remember not to close it right up though or you risk straining something. CR2032 batteries are pretty cheap and they give you a spare battery as well as the one fitted when it arrives. With a bit of care, battery life should not be an issue.MY FIRST ONE WAS FAULTY: I noticed that when pressing the 'ZERO' button, the display always said '7.77' or ‘0.01’ instead of '0.00'. Measurements sometimes worked normally but in some lighting conditions it was all too easy to see the parts of the LCD that you should not be seeing - which makes reading it a bit worrying. Having realised that problem, I gradually opened up the jaws beyond my normal range and I noticed that there were a great number of random readings appearing. Far too many to be acceptable, so my first one had to go back. Fortunately, the replacement is a brilliant tool at a bargain price.ACCURACY: To test the Preciva, I measured three drill-bits (5.00 mm, 2.50 mm, 1.20 mm) with 5 different devices. I measured each shaft three times with each of the 5 instruments - i.e. 15 measurements of each object. The table below shows the average result in millimetres. (The table may not survive re-formatting by Bolo so read carefully).NOMINAL SIZE: 5.00 2.50 1.20Vernier Micrometer: 4.957 2.508 1.200 These readings did not vary.Vernier calliper: 5.02 2.54 1.26 These readings did not vary.Plastic calliper: 4.70 2.30 1.10 Varied by 0.20 over three readings.Faulty Preciva calliper: 4.94 2.49 1.18 Varied by 0.10 over three readings.Second Preciva calliper: 4.96 2.50 1.19 Varied by 0.02 over three readings.The micrometer readings and the Vernier calliper readings were absolutely consistent. The Faulty Preciva and the £5 plastic digital calliper varied with each reading but the Replacement Preciva varied only very slightly…On the ‘5.0’ mm object it varied 0.02 mmOn the ‘2.5’ mm object it varied 0.01 mm.On the ‘1.2’ mm object it varied 0.00 mm.The measurement ‘error’, if error it really is (probably is), is a maximum of 0.01 mm. All of those results are pretty damn good for a budget calliper!My Vernier micrometer reads '0.00' when closed right up, using the torque limiter. I would guess therefore that it is reliably accurate at these small measurements. On that assumption, the Preciva calliper is more accurate than the Vernier calliper(!) and it is of course much quicker to read than the Vernier calliper. Very rarely will I need anything more accurate than the Preciva and if I did, I would be using a micrometer anyway – so the Preciva is a bargain!CONCLUSION: It is a shame about the faulty LCD on the first Perciva but the replacement one is a gem. Highly recommended and well worth 5 stars at that price.The £5 plastic calliper result was interesting. It is the least accurate, as should be expected, but for most purposes, it is good enough. How often do you REALLY need to measure closer than 0.3 mm?PLEASE NOTE THAT THE PICTURES ARE OF THE FAULTY ONE. THE REPLACEMENT IS 'PERFECT'.

5.0 out of 5 stars Great piece of kit for the price

C.&.C. · 30 March 2025

The media could not be loaded. Instead of using measure or rule for some jobs, I decided to try a digital caliper. For the price, it seems decent quality with a hard case, decent instructions and spare battery. After a quick test I think the screen is a decent size, and I like the way it does internal and external sizes (although other calipers will probably do the same). Although this is my first caliper, I am hoping it is precise enough for what I need. Over time of using it I will adjust my rating accordingly if I find it is not precise enough, but fingers crossed it will be fine.

Measure to the fraction of a mm with ease! No complaints - great build and good display.

Great product

1.0 out of 5 stars Absolute junk

A.H. · 5 June 2025

Waste of money. The digital readout is constantly jumping up by 5 or 10 millimetres despite being zero'ed. You need to take a dozen measurements to be able to find an average. I didn't realise this before buying replacement bushings which were completely wrong.Absolute waste of money, avoid.

Pied à coulisse numériques. Avec grand 'écran. Bien lisible. Par contre Sur Mon pied à coulisse Le compartiment a pille Ne s'ouvre pas facilement Pied à coulisse. Semble de bonne qualité. Pour un prix correct Par contre Mais je doute sur la durabilité A voir

Pied à coulisse robuste

R. · 31 May 2025

The media could not be loaded. Ce pied à coulisse électronique en aluminium offre une bonne prise en main et une lecture claire grâce à son écran digital. Il est léger, ce qui le rend agréable à utiliser sur de longues sessions. La précision est satisfaisante pour un usage courant, et la construction inspire confiance. C’est un outil fiable et bien adapté aux besoins d’un bricoleur ou pour un usage en atelier léger.

Alta precisione e ottima visibilità

Un ottimo calibro alta visibilità e molto preciso

Good value

R.M. · 25 March 2025

good build quality and value. The only bad thing is that in case the display would fail, it can't be used propperly (if you use mm but need to measure inside diameter, the scale for that is printed in inches ) So once the display unit dies, it really won't be usable. Good thing it comes in a sturdy case and well machined housing, so I wouldn't worry too much about it. Extra battery is included.
