If you work in construction it would make your life easier. It takes some getting used to the range of functions however if you are a joiner the stair function and traditional cut roof functions are great. You can input metric or imperial although the inputs are more logical when done in imperial and use the American phrases for roofing and framing. It has a good instruction booklet however the you tube channel is the best resource. The quality seems to be very good but came with a tough case too. Well worth the money.

I use it a lot myself, so hope he will get me one soon. **Q: I have a older version...maybe 5 yrs? Is this one more advanced?** A: Thanks for your question. There have been no significant changes to the Calculated Industries 4065 Construction Master Pro Advanced Construction Math Feet-inch-Fraction Calculator in the last 5 years other than the addition of the Armadillo Gear as standard. If you have one that is no longer working, you can send it in for repair. **Q: Does the CI 4065 pro delivered have an orange back or black back?** A: the calculator it's self has a black back, i got mine with the armadillo gear cover and the main body including the back is orange but the flip cover face is a dark graykevin **Q: Will it tell me the amount of concrete i need for a slab?** A: Thanks for your question. The Calculated Industries Construction Master Pro Calculator will calculate cubic yards using the Length Width and Height keys.
