Calculated Industries 4065 Construction Master Pro Advanced Construction Math Feet-inch-Fraction Calculator for Contractors, Estimators, Builders, Framers, Remodelers, Renovators and Carpenters

A little confusing at first but very useful tool in the field. Works better then a comprable app. The protective case is a nice touch.

The calculator is great, but should have a much better manual for the price. I had to go download the full manual which is about 100 pages and print it out, it should have come with a much better manual!!

La utilicé para hacer una casa para nuestro perrito

I purchase this calculator for work over a year ago, and it makes my job easier than using a regular calculator for figuring linear, square footage, slope, and inches. I use it everyday at work, and it is very easy to use. The functions are straight forward and I like the back button if you punch the wrong key. I recommend this item.

Great calculator large enough to use easily

Received item and it doesnt turn on. Replaced batteries and still it will not work. A piece of trash!

It works

My son-in-law, a contractor, thinks its great.

I was all set to love this calculator until I discovered it doesnt calculate rafter tail length. Then I found that the 4067 model does calculate total rafter length including the rafter tail. I returned this item and intend to purchase the 4067 model in the near future. Excepting for not calculating total rafter length, this calculator is very, very helpful.

I have the app on my phone, but it eats my battery up while Im working with it. So I went with this little guy. Very handy for the work I do, Ill probably never use all of the functions it has, but its nice to know its there.
