Aproca Hard Storage Travel Case, for Calculated Industries 4065 4080 Construction Master Pro Calculator (Case Only)

I recently bought this case when I bought a Construction Master Pro for the purpose of protecting the calculator when it's not in my pocket. When I received the order of the calculator and this case I was pleased to discover that my Construction Master Pro included an Armadillo case so I began the process to return this to Amazon, then I got thinking.... As you can see, this case is big enough to enclose and further protect the Construction Master Pro from bumps, falls, and rain, AND also carry several useful items while still being relatively compact. I have two .9mm mechanical pencils in mine for normal writing or notation, a Thorvald mechanical carpenter pencil for layout marks, a red lead carpenter pencil for specials layout, A Sharpie for making indelible notations on drawings, and a container of replacement .9mm leads for the small pencils with a little room left over for something else, maybe Thorvald leads? The case and zipper seem to be well made and I expect them to hold up for a long time while containing a small layout and calculation kit in one location. With the built in strap and a carabiner it could be attached to a belt loop or belt, if so desired. Definitely decided to keep this case.

Works and fits the calculator in its case it comes in!! Fits just as in the pictures on the product page. I got it specifically for the calculated industries construction master pro v3.1.

My construction calculator HeavyCalc Profit very well in the case

its super fast at calculating. easy to use. fits my pens and highlighters and zips shut for compact storage and easiness of carrying. great price for protection of my calculator.

Very handy and well built .

Works great better than expected

I got an empty case, no calculator.

This unit will help you with your calculations but you will have to read, reread as to how to do it until you learn the process. The best thing to do is get on You Tube and watch their videos as to how to use it.
