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

great product

Goes well beyond my required conversion for decimal, fractional calculations. The supplied manual is very basic but they do have and extensive manual for a cost. Would be nice if the course manual would be included or at least available online.

dos what i got it for

buen producto

Perfect for the price

good purchase

Love love love my calculator, makes adding and subtracting and multiplying feet and inches so easy. Even figures dimensions for stair design and just an overall great tool for people that need to deal with alot of calculations in the imperial units system.

works great

I have used this before from a friend and it cut a bit of time out from doing various calculations so I bought one for myself. Its not all perfect though, there are some calculations that it cant do and learning how to use it if you never had before may take a bit. Dont use it for the first time while working, like everything else you have to learn the device first.

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