Housed in a rugged, jobsite-ready case and featuring a safety-compliant battery design, it empowers professionals to solve complex dimensional problems quickly and accurately, reducing errors and material waste on every project. ## 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.

In the field or office, get the job done right the first time! 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: Been a fan for thirty years! - 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... ## Features - SOLVE YOUR DIMENSIONAL MATH: Quickly and accurately with the award-winning CM Pro Trig construction calculator's powerful built-in solutions for completing layouts; and full trig functions with sine, cosine, tangent, arcsine, arccosine and arctangent - EFFORTLESS CONVERSION CAPABILITIES: Work in and convert between all common building dimension formats: feet-inch-fractions, decimal feet-inches, yards and metric - including area and volume.

The external case is perfect if you work outside doing construction. It is very durable. ### ⭐⭐⭐⭐⭐ Been a fan for thirty years! *by R***T on February 12, 2024* By trade, I am a structural and miscellaneous steel draftsman.

Overall, I am a very satisfied customer... ### ⭐⭐⭐⭐⭐ Best invention since sliced bread !!! *by R***Y on March 19, 2013* This has to be my fifth or sixth Calculated Industries calculator purchase. I have two at my work, two at home, I keep one in my car too. I'm glad that my 4080 Pro came with the rubber armor as this should help with using it in the field and getting dropped. If you want a calculator to do the work of figuring feet and inches, cubic feet, square feet, stair layout, rafter pitch, volumes, board feet, material quantities, ounces, pounds, converting cooking measurements, figuring mortgage rates, time cards, payroll related calculations, handheld machining math, thread data, drill size chart look-ups, speeds and feeds, right triangle solutions, bolt patterns, estimating, takeoffs ...... the list goes on and on and on and on...... If you need a calculator to help with the items mentioned above than look no further than Calculated Industries. I work in a structural engineering office and this is my second 4080 Pro. I love the fact that it has "Trig" functions as well as the basic feet and inch functions. That is about 1% of what this little machine can do. I starting drafting with a 'T' square and now working on Revit so I've seen a lot change in my career. I wish I had the 4080 Pro when I was a younger draftsmen. It is an indispensable tool in my electronic briefcase of gadgets. As long as Calculated Industries is in business and I have a need for their calculators, I will purchase no other brand. Good instructions, ease of use, good battery life. ## Frequently Bought Together - Calculated Industries Advanced Construction-Math Feet-Inch and Metric Calculator with Full Trig Functions,Silver - Calculated Industries 2140 Construction Master Pro Workbook and Study Guide | 4 Comprehensive Sections | Site Development | Footings, Slabs, Walls | Framing | Finishing |Practice Problems, Answers --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.bo/products/1154922-calculated-industries-4080-construction-master-pro-trig-calculator](https://www.desertcart.bo/products/1154922-calculated-industries-4080-construction-master-pro-trig-calculator) --- *Product available on Desertcart Bolivia* *Store origin: BO* *Last updated: 2026-08-08*
