Calculated Industries 4225 ConcreteCalc Pro Advanced Feet-Inch-Fraction, Metric Construction-Math Calculator Tool for Concrete, Masonry, Paving Contractors and Estimators

Can't stand being without it. To be honest, I don't use many of the preprogrammed formulas but if you're not so good at math this is a must have. The one thing I can't do without is the ability to enter feet and inches. That is priceless, results in more accurate calculations. The square up and volume functions save yiu loads of time too and the stair function is very handy when yiu know your total rise and want to figure out how many steps you need to form up with a given tread width or you can designate a total run and have it figure your tread widths. There are a lot more functions I'm sure are useful that I just haven't gotten to yet.

This is my second Calculated Industries 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 use this product to calculate the amount of concrete block it was going to take for a large Housing Authority project. 58,000 block. Of course that's seven or eight different type of block and I was able to calculate them precisely in no time. That is my favorite feature is the capability of figuring the amount of concrete block and the amount of brick I may need her project.

I bought this as an open box item. It was like new just cheaper I would not hesitate to do the same thing again. I found the youtube videos on setup and use very informative. Wish I had got this thing years ago.

One of the best calculators I have owned

Great calculator

I have done all my calculations using various fractions of a foot to get volume totals. This calculator has all the necessary keys to handle every possible need for working up needed volumes ordering concrete.

This company makes physical calculators as well as apps of the same layout as the calculator. Theyre proud of both but they are awesome. I have 2 of these and the app.
