All of our superintendants love using this concrete calculator. Please don't even think of changing it. We also like the orange case.

My husband needed this calculator for work. It's accurate and durable thus far. He uses it daily and it's holding up pretty well. It arrived on time.

I bought my first concrete calculator in the early 90's. It does everything and I need quickly and accurately, who could ask for more.

I could price my jobs and order concrete without it, but I WON'T. I have two of these calculators and they are very accurate and make my job easier.

I am a concrete finisher this calculator works great. If your bidding on a hob this will help you figure things out a lot quicker than doing it on paper.

This is my second Calculated Industries concrete calculator but my first Concrete calc. Because I used my first Construction Master for so long and it did not have trade-specific features like figuring rebar, I tend to use my old workarounds out of force of habit. But, someone younger in the concrete business would use those often. The major upgrade for me is the Armadillo case which was included on my model. IT allows the calculator to take a lot of abuse. If you are ordering concrete or concrete materials everyday for flat slabs, you probably do most of the math in your head. But, if you pour a variety of shapes or depths, battered walls, or need to do a lot of dimensional work in feet and inches this is worth every penny.
This tool really earns its keep squaring rectangles and figuring stairs.
It is one of my favorite tools.

I poured some footings the other day and used my concrete calc pro. When the driver got there, he said i don't think you ordered enough mud and i was trying to figure out what i did wrong. Turns out he was wrong, when we got done, i had about a half a wheelbarrow extra. Perfect!
