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

This replaces one I have had for YEARS. Definitely wanted the same brand to replace it.

Works easy and good

This calculator saves so much time and money!

Helped me pass my test first try.

It even adds 2+2 and gets 5!!!

Perfect product for its use

I Love my construction Master calculators. Ive had to purchase several because my crews has dropped them from height or into water. For my crew leaders I found it cheaper to buy the app for them. Apparently they take better care of their phones. LOL. This replaced my personal one that I have for many years. It was before they came with the tough case and it had lasted maybe 15 years of daily use. It is still functioning but the buttons have worn out to the point that I have to push really hard. I expect this one to last even longer

So far we have mostly used it for squaring lines and checking right angles, but it is awesome for doing anything with feet, inches, and fractions.

Worked out great as a gift

Easy to use
