    Makes math easy!
    Honestly I picked out this calculator not knowing quite what to expect. I rarely work with concrete but I had and still have some concrete work to do most of it setting some fence posts in concrete. I remember last time I did fence posts I was mixing to much or to little concrete and it was a total hassle. Well not this time, with this ConcreteCalc Pro it has made figuring out the amount of concrete I need to mix very easy so I am not ending up short and not mixing to much so it has made life very easy there. I also got this calculator to act as a construction calculator to do things like square footage, cubic feet and conversions. I have barley cracked the surface of what this calculator can do but even I have been able to figure out enough basic functions to get by and I am absolutely horrible at math even with a calculator lol! It is nice because there is a slot in the back of the calculator for the small instructions manual and there is a quick reference guide inside the lid of the Armadillo case that comes with it. The Armadillo case that it comes with is great and protects the calculator very well, I submitted mine to some torture testing where I repeatedly dropped it from 10 feet and also threw it very hard at the ground multiple times and it never sustained any damage at all! As far as functions and things don't expect me to explain to much, check out the descriptions and they will tell you the kind of things this calculator is capable of and check YT for some instructional videos. I am definitely glad I picked up this calculator and even though I have only done small amounts of concrete work with it the calculator made it much easier and helped me not to waste material. I definitely highly recommend this calculator.

    Great tool for Contractors
    The ConcreteCalc Pro Calculator is a great tool for all contractor pros. Not only does it do all of the calculations needed for concrete work, it can assist flooring sales by finding the correct areas. All of the correct formulas are available for most construction problems with conventional measurements as well as metric. I sure could have used this for multiple projects. The Armadillo Gear case is a great plus! Althought the Home Depot site shows a pocket for manuals, mind does not have the pocket (minor problem.) See manufacturers website https://www.calculated.com/prd104/ConcreteCalc-Pro-4225-Concrete-Calculator.html# for video instructions on how to use. Phone Apps are available.

    Plenty of Features
    It's a solid and accurate calculator. It has plenty of conversion features. I think that the Construction Master 5 is easier to navigate. The manual is straight forward. My only concern is figuring pours too close with this calculator. Depending on what the batch plant actually sends in a load could do you more harm than good. Not using the 10% extra concept could leave you scrambling to order another load. The advantage of this calculator is more in the project design/engineering phase, less in the field or on-site.

    Great durable jobsite calculator for the concrete contractor!!
    This is a great tool for any concrete contractor or builder. The calculator comes in a built in style heavy duty casing. It also has a flip top to protect the buttons. On the under side of the flip there are notes on using the calculator. This is great tool for figuring concrete volumes for different dimensions. (walls, footings, foundations, flatwork) I would strongly recommend. This is a great replacement for sliderulers. It is very durable for leaving in the truck or working on the jobsite.

    The best tool for material calculations
    I updated my material needs calculations by getting the ConcreteCalc Pro Calculator. This calculator is designed for people that need to determine accurate material calculations on the fly. It has a drop resistant Armadillo Gear rubberized exterior cover with a quick reference guide on the inside of the cover. It also has a reference guide in Spanish that can be installed over the English version if needed. This calculator has been very helpful in calculating the materials needed for concrete, asphalt and paver driveway and patio applications. It saves your calculations for later reference or for comparison to other contractors calculations for bid purposes. It is easy to use and very versatile. It has paid for itself on the first day with an accurate set of calculations that won a bid for me on a driveway install. Rugged and dependable this is my first choice for accurate calculations on the jobsite.
