    Fantastic product. I use this at my desk for quick drafting calculations. Wish it had some grip on the bottom to keep it from slipping around. The rugged case being removable is fantastic. Love it.

    Best Construction Calculator on the market. I use the Construction Master android app on my phone when I dont have my calculator with me, but I am old school and like the tactile feel of buttons.

    Perfect calculater for framing good for roof cutting stair cutting for figuring any triangle you can think of also segmented archways and much more just wish buttons would last longer I have to buy a new one every year because buttons wear out a waterproof model would be nice although I havent had any problems in wet weather its always a concern

    This calculator comes with a case. You do not need to buy one separately. Otherwise very helpful calculator

The Construction Master is and has been the industry standard for carpenters and craftsmen for over 30 years. Its use is taught in apprenticeship and training programs at the high-school, college, union and industry level across our country and beyond. An entire generation of framers and stick-builders grew up using it and advising us on new capabilities they wanted built-in. Building materials and techniques have changed over the years but geometry and the need to work quickly and accurately with dimensions is as important and difficult as ever. Put the time-tested Construction Master Pro on your next project and you’ll be glad you did.
