## Description

Product Description The Construction Master 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. The Construction Master Pro TRIG has those features built in including full trig functions. The trigonometric calculations include sine, cosine, tangent, arcsine, arccosine and arctangent. 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. Button-Cell Battery Safety Compliant Design -- This product uses a button-cell battery housed in a compartment secured with a tool-required fastener. The battery is not accessible during normal use without a tool, supporting alignment with applicable U.S. consumer product safety requirements for button-cell batteries. Put the time-tested Construction Master Pro Trig on your next project and you’ll be glad you did.

Review: Recommended for construction workers - Good calculator does everything I need easy to use long battery life great value for the money. The external case is perfect if you work outside doing construction. It is very durable.
Review: Accurate and durable. A real tool. - I still have my original calculated industries calculator from decades ago. The only reason I purchased another. Two buttons on my old one stopped functioning after about 25 years. On construction sites. That's pretty damn tough. And accurate. One of my best tools. I highly recommend it.

### ⭐⭐⭐⭐⭐ Recommended for construction workers
*by A***R on January 18, 2026*

### ⭐⭐⭐⭐⭐ Accurate and durable. A real tool.
*by J***D on August 8, 2026*

I still have my original calculated industries calculator from decades ago. The only reason I purchased another. Two buttons on my old one stopped functioning after about 25 years. On construction sites. That's pretty damn tough. And accurate. One of my best tools. I highly recommend it.

### ⭐⭐⭐⭐⭐ Been a fan for thirty years!
*by R***T on February 12, 2024*

By trade, I am a structural and miscellaneous steel draftsman. When I started in this line of work, there was a limited amount of calculators to choose from, and most of them required the user to work in decimal form only. Then, I found the feet-inch calculator from Calculated industries. It changed everything for the better. The biggest advantage was that it cut down on the human error. There are times where I will have a string of dimensions to add or subtract. One of the features which aids in this is the "paperless tape". It will keep a running log of the current function the user is performing much like the old adding machine tape. The calculator only got better as time went on. The addition of the trig functions was a huge bonus. Probably the only con I have is it has a limited amount of memory storage. It only has three storable memories, and sometimes, I could really use five or six depending on the formula I have to run. Overall, I am a very satisfied customer...
