NeoRuler Digital Scale Ruler, 12 inch Smart Scale Ruler with Infinite Customized Scales and ±0.004 inch Accuracy, 93 Built-in US Imperial, Metric Scales, Architectural and Engineering Scale Ruler

Excellent product.Would of been nice if available 20 years back while globetrotting for the Telecom business.Will be well used

Works great. I do a bunch of estimates from prints and they are not full size. The ability to calibrate it to the size is perfect.

The accuracy appears to be good but the indexing of the default cursor needs to be more definitive. Something similar to the hair-line cursor of a slide rule would improve it substantially. The magnifier cursor resolves this problem. I also found that adding one SMALL drop of a liquid Teflon lubricant to the slides in the main body improved the functionality of the device quite a bit.

I really wanted to like this but I found it more cumbersome to use in practice than I expected. My triangle rulers with multiple scales on them that are easier to use. The slide is stiff to move and I spend more time trying to get the slide perfectly lined up while keeping the zero point located than I save by having multiple built-in scales in the device.While I think there is a lot of promise here, for me this is more of a gee-wiz kind of tool than something useful. A more useful design would be a good first step.

Amazing scale to use at the jobsite. This scale scales the physical drawings without the hassle of scanning them and uploading into bluebeam/onscreen softwares to adjust the scales. By connecting the scale to Bluetooth you can start the calibration of the scale to start measuring. You can also pinpoint the drawings using the meazor application for the scale. Overall very satisfied with this scale.
