User friendly and will continue to use for jobs. Came quickly and good price. ### ⭐⭐⭐⭐⭐ Way better than an app *by D***S on May 12, 2025* Great product. Arrived fast. I was tired of an app version changing after every update. So glad I found this no more apps ### ⭐⭐⭐⭐⭐ Handy tool *by R***N on November 21, 2024* Years ago when I was building and cutting roofs I relied heavily on Marshall Gross and a TI-35 calculator(IYKYK) and was able to calculate anything I encountered. Fast forward 25 years where work and life have taken me other places and I was no longer using Trig and geometry on a regular basis, my ability to calculate has diminished. It would probably be fairly easy to go back and brush up with the help of Roof Framing, but I decided to come into the light and try a dedicated construction calculator for a few planned fanciful construction projects. Enter the Construction Master Pro. I haven't had it long enough to attest to it's durability but I'm confident that the Construction Master reputation for quality is deserved. Fortunately, mine also came with an Armadillo Case, which seems like it will be great for protecting the calculator. I took it out of the box and started performing calculations with the included quick start guide, which stores very conveniently in the back side of the calculator. Keystroke sequences are not always intuitive if you are accustomed to using a scientific calculator for these calcs, but it seems that with a little more practice they will became second nature, and there are short cuts built in to the process for more advanced calculations. I'm looking forward to mastering this calculator.....I definitely recommend it's purchase. ## Frequently Bought Together - Calculated Industries 4054 Construction Master 5 en Espanol Construction Feet-Inch-Fraction Calculator for Carpenters [Calculadora de construcción con pies, pulgadas y fracciones para carpinteros] - Calculated Industries 2140 Construction Master Pro Workbook and Study Guide | 4 Comprehensive Sections | Site Development | Footings, Slabs, Walls | Framing | Finishing |Practice Problems, Answers - Aproca Hard Storage Travel Case, for Calculated Industries 4065 4080 Construction Master Pro Calculator (Case Only) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/29171264-calculated-industries-4054-construction-master-5-en-espanol-construction-feet](https://www.desertcart.co.za/products/29171264-calculated-industries-4054-construction-master-5-en-espanol-construction-feet) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-04-22*
