So far he likes it

I bought a Construction Master III in 1993 when I built my first house. At the time, I was a general contractor. Its been decades since I have done construction professionally. But I have used the calculator periodically through the years for various personal construction projects. I bought the 4065 Construction Master Pro thinking there must be some substantial improvements over the last 30 years. It does have a few new features, but most of those are accessed using a combination of keystrokes which are difficult to remember. The markings for the alternate functions of the keys are very tiny and difficult to read. The manual, which is often needed to determine the keystrokes needed for a particular function, is difficult to get to. You have to pry the calculator out of its armor case to get the the manual tucked into the back. On my original calculator, the manual is tucked into a flap on the case, and is readily available for reference. So, I returned the 4065, and will continue to use my 30 year old calculator. In general though, these calculators are very useful.

I am yet to get to know how to use this well worth tool effectively so with the help of friends like Google and Youtube I am on my way. It is a very helpful tool for my workshop.

I have owned this Estimating Calculator before. After 7 yrs of daily use the On/C button finally gave out. I had to use the reset button instead of the On/C and that worked fine. It was unfortunate but I really put it through its paces. I decided to get a new one and keep the old one as a back-up. I did not hesitate to get the same one since it did everything I needed. If you do multiple types of construction materials this does pretty much everything you need.

One of the best calculators you can own

I recently purchased the master pro trig, and im very happy with it. Im a carpenter by trade and do alot of framing, this this does away with the need for all the math or tables for irregular roofs ect. brilliant!!

The calculator is very intuitive easy to learn. It made quick easy results for some tough problems. I would buy it again.

It was cheaper than at college bookstore. Many uses! not just construction. My mom steals it all the time for her quilting projects.

Love it! Fast! Accurate!reliable!

My husband is very pleased with this product.
