instructions could be better this tool saves me a lot of time and eye strain

You often get a copy of a construction plan and discover that the print is enlarged or shortened when you are more rushed. Your crew asks for dimensions. Then, the ruler steps in and saves the situation!

It saves so much time compared to using a manual scaled ruler. The BEST feature though, is the custom scale! We have customers who send us screen shots of floorplans, and we would spend so much time trying to scale them. This ruler does the job! Love it!

I really want to like this device. in theory it would be a game changer. One big issue i have with it is when using custom scales you can only use inches so you have to convert every measurement to feet. also I find it to be less accurate than I had expected. I thought the little magnifying glass would make it more accurate but it doesn't, the pointer on the mag glass is super thick for that to be beneficial it would need to be like a wire. I often set a total measurement for custom scale and find when adding all the points between together I do not end up with that total measurement. again I really do want to like this device but I get closer results using a tape measure and doing the math to find the scale of whatever is printed then using that scale and the tape measure.

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.

My grandson was thrilled with this for his Christmas gift

High quality. Ease of use. And Ingenuity. There’s a practical use for this digital ruler. I bought this for drafting/layout for hvac fittings. It’s more for engineer work. I.e. reading and designing prints. I have no complaints. It works as advertised.

342 / 5,000I'm very disappointed. I used the ruler on two projects measuring buel prints, and it worked very well for six months. Upon reusing it, I realized I felt three jumps and it was hard to move the ruler. I realized they were some very small screws that had come loose. Every time I try to measure, I hit the screws that hold the ruler in place.
