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

Good quality case came on time with no issues

I like this little shell, which is rigid & very protective of my ridiculously expensive Construction Master Pro calculator. It has a nice, smooth zipper. It's a little bulky, and I haven't had a chance to use it in the field yet, but I appreciate having it to take to class. The elastic on the interior is nice and sound and the carrying strap is no-frills, but sturdy and well attached. I suspect this will last for a good long time.

Got it for my chem 1412 class and I was able to use for the end of 1411, it gets the job done

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.

Great investment to protect your expensive calculator!
