Calculated Industries44080 Construction Master Pro-Desktop Advanced Construction Math Feet-Inch-Fraction Calculator with Trig Tool for Architects, Estimators, Contractors, Builders and Remodelers

I have been using one of these since the 1990s for construction take offs and framing.

We had a pocket Construction Master Pro prior to this and also used the app for the iPhone, but we wanted a desktop version for my husband who has much larger fingers. He was getting frustrated with the iPhone app as it constantly read the wrong tap on the screen. This has saved his iPhone from being tossed to the ground on more than one occasion!

The calculator work wonderful for my needs.

Way bigger than I thought it would be. But I do hear that a lot. Would be way better if it was solar powered but it shuts off automatically so assuming the battery will last a while. Great product especially if you know how to use it.

Bought this for my wife's uncle who does construction estimating. his exact words "it's huge I love it" the numbers are big making it easy to use and the display is very legible.

Good shipping and good price.

BTW. Hit "Conv" then "On/C" to instantly turn it off.

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.

Its for stair working out etc

This calculator was delivered only last month and now it is no longer working. The display freezes. The only number that appears is 0 or 8. I tried to reset it but probably even the reset button is working. I am an estimator and I use this product every day 8 hours a day. I had another which is called Construction Master 5 and I had been CM5 since 2008 until it broke down last March.This product is a waste of money. The last day to return this product was last May 2. I think the product would lasts only a few days after the last day of product return.

The larger size of it makes it nice for desktop use. One thing I wish it that it had the same key layout as the Construction Master 5 that I've used for years on the jobsite. It would be really nice if there was dedicated keys for the cm and mm. Because the Canadian Code is all in metric I use it a lot for converting mm and m to feet and inches. Otherwise it's a good addition to any office that is involved in building construction.

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

Fast & accurate. I'm happy
