Calculated Industries 44080 Construction Master Pro-Desktop Advanced Construction Math Feet-Inch-Fraction Calculator with Trig Tool for Architects, Estimators, Contractors, Builders and Remodelers

Nice size for desk- easy to use, easy to read. Seems heavy duty and should hold up well with daily use. Good value for the money.

Great product I have used the small handheld models for over 20 years and this works just as good and easier to see the numbers.

Has all the features of the 4065 and the 4080 trig model. I also have the 4065 which is more portable. Not exactly portable but it's awesome!! All of the construction master calculators are incredible. Also they have a huge library of videos on YouTube and if you get stuck you can call them and there's always a person there that can help walk you through it. Great customer service. Every time I've had to call it's a real person here in the US. Can't say enough good things about this calculator and the company.

Outstanding constellation calculator. Love the large screen and the accuracy of it.

Grudgingly ordered this after having to switch back to an older phone and the factory wipe removed my app only to find out it could not reload the app because CI doesn't support Andriod 11 anymore and wont allow access to older versions that did. This is a must for anyone doing desk work and currently using the app or pocket version. Larger display, larger hard buttons, much easier and more efficient to use. Hopefully more durable. Before going to the app I was going through the soft button pocket version at a rate of 1 per year.

I love the functions on this calculator. It does absolutely everything I need and a LOT more. What is lacking, for me, first and foremost, is button accuracy. Sitting flat on my drawing table, with nothing to absorb my presses, I get missed key presses far too often. I am used to blind entry on a 10 key numeric keypad, and my old Construction Master made it 25 years before it was time to let it go. I have had this one less than a year, and it is not wearing out. It has been that way since out of the box. So I lose time watching every key press, every single time. That extends bid time out a good bit when adding up a large project. And I am still not 100% comfortable with my numbers a lot of the time. A lot of double and triple checking myself to make sure what my fingers felt is what went into the equation.Second thing, for me, is even with the adjustable angle readout, I get a glare most times and have to move it around to get just the right lack of reflection on the readout. Seems to me a slightly matte finish that doesn't bounce light so hard might be better, but I am not about to scuff up the screen. As for the function and accuracy, as long as the keys record my input correctly, you can beat this one! As far as that, I trust it

I'm a fabricator and the construction master pro calcs have been staples in the toolboxes of the guys in the shop for years so when I learned that they made this I had to try one. This does all the things that the smaller calculators do and give even easier access to trig functions so it's a win win for functionality. I like the book that is included, it's a little clearer than the little booklet that comes with the other calculators in their line, it is more expansive and clearer which makes getting the most out of the calc easier for those functions you don't use all the time. It's big! I actually wish it was about a third smaller than it is for use on the shop floor but if you actually use it on a desk like it's supposed to be or have eyes with some years on them then it will probably be right up your alley.

Must have for construction calculations

Its for stair working out etc

it would s a high quality calculator that is easy to use, with the large buttons and display. does easy calculations for stairs, rafters etc, converts metric into feet and inches and back in one easy step.

was the expected one,..great!!

This calculator is very convenient to use because it is so big. Very helpful for an engineer working on structural detailing.
