Works even better than the Constr Master IV that it replaced.

I've used the construction master IV for years, it did what I wanted it to do. So I went shoping found the Master Pro, and it made calculating construction figures & estimates so much easier. Love it I'll buy another one, unless you come out with one that does more.
Thank You

I do rely greatly on your products and we have many contractor who do also. I have a Construction Master Pro sitting next to my key board at all times, a Construction Master Pro DT Printer and Scale Master Classic on my main desk and a Trig Plus II and Scale Master II in my briefcase. Now that I have a Droid X I'll be loading your app on it also. I don't understand how a true contractor lives without your products. I feel it's products like yours that make the difference between a Professional Quality Contractor and a wood butcher.

It will be outdated soon because of computer estimating programs. However it is still great for quick calculations for small projects, and alot less expensive than the computer programs.

I had recently married a man in the construction business. I was lost when it came to measurements. I had no experience in this profession. Now, i can easily figure pitch, width, height, etc. The dvd that came with the calculator showed me exactly how to input the data and come up with the correct answer, it was so easy to understand!

I am using it for both work and school. For work it has saved me so much time but in school we need more soft conversion than hard conversion(ex. inches to cm, or yards to metres). It would be nice if you had a calculator with this ability!

It needs the other exponent button, not x2 but x-1. I am using it for the engineer field and I might buy another one (the bigger one of course). Everything else is on the money.

I use it on every house. I just tote it like I do nails in my nail apron. You really need one if you are going to put rafters on a house. It's just hightly invaluvable. You figure up the measurements one time and you cut the rafters. You don't have to check them.
