Review: Perfect tool - Will fit in tee shirt pocket. Love the trig functions. Had to carry two calculators now I just have the one.
Review: Very useful to anyone - As a home building contractor, I used these Calculated Industry Construction Masters many times a week. In the old day, things like cutting rafters, building stairs, calculating amounts of building materials all had to be done the old fashioned way. These calculators saves a ton of time and are always correct if the data is entered correctly. I will also say it s very handy for a lay man or anyone that does things around their house, that involves volume, square footage, adding measurements together and much more. There will be a time when you say to yourself, Jeez, I wish I had bought that

### ⭐⭐⭐⭐⭐ 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.
