This is a very good tool for takeoffs. Very accurate and easy to set scales and roll around on plan pages. Read more
This is handy for doing takeoffs on plans. It has plenty of preset scale lengths to use and some customizable scales for when you are taking off poorly scaled plans. It has your basic length, area volume measurements, a counting function and you can convert units. There is a rubber grip where you hold it and it helps keep your hand steady. The little notch on the bottom goes just above the paper so you can get precise measurements (see photo). This version is non rechargeable and takes two CR2032 batteries. If you are unable to takeoff using a computer I’d recommend this. Read more


If you deal with plans this is great to have. Easily calculate footage sq footage of rooms and much more. I love this thing and have with me all the time on site. Great to use when mapping out runs for pricing and sizing wire/pipe. Use to check measurements when laying out Read more

Works great just like my old one Read more
Comes with a very nice case. Good instructions. This can be very sensitive and accurate when on job site. Specially getting down to some of the smaller fractions, but makes things quick for accuracy. Read more
So far this has been a very accurate device. For a quick take off on prints when you aren’t on site you can get a very accurate measurement. This with the architecture ruler are must have tools for any trade working in construction. Read more
