Calculated Industries 4065 Construction Master Pro Advanced Construction Math Feet-inch-Fraction Calculator for Contractors, Estimators, Builders, Framers, Remodelers, Renovators and Carpenters

Great calculator! Long battery life makes computing fractions a breeze!

Quality is great! Display is a good size!

Has all the features of the 4065 and the 4080 trig model.I also have the 4065 which is more portable.Not exactly portable but it's awesome!!All of the construction master calculators are incredible.Also they have a huge library of videos on YouTube and if you get stuck you can call them and there's always a person there that can help walk you through it.Great customer service. Every time I've had to call it's a real person here in the US. Can't say enough good things about this calculator and the company.

My old one finally wore out after maybe 20 years, so I bought a replacement that should last me until I retire in another 20. I like that the company is out of Nevada not far from where I used to live. I don't use half the functions, but it's nice that they are there. Strong case protects it well.

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.

I like the product. I have had one before. It was supposed to be delivered within 4 hours by 6 PM yesterday evening. It got here at 4:30 this morning. It was left on the edge of my porch, where it rained. Amazon delivery is getting worse as it goes. Between late packages and your package seems to be lost.

Works great, cover saves from the dust

I’m writing this review 5yrs later! This is by far one of the best investments I have made makes my job easier. I am a carpenter concrete foreman so this calculator helps me out a ton when I need to order material and even when I am dealing with slope percentages etc. It’s awesome and can take a beating too it’s been in my bag pouch ever since.
