Customer Reviews

Best feet / inch / fraction calculator!
Having tried many feet/inch/fraction calculators, I must say this is by far the easiest to use, and the case it comes in can take a beating while protecting the keypad. There's even a compartment to keep the operator's manual with the calculator and protected (which you will use on occasion for calculations that you don't do every day). I have had the predecessor to this model, the Construction Master 4 for years, use it daily, and still have never had to change the battery.

Construction Master V
The price and service from Amazon was superior to anything I've used on the internet. The calculator also has exceeded my expectations ( I had used the Construction Master IV for 8 years, until it just wouldn't work any more ). I would recommend to anyone both the service and product provided here.

Continues the heritage
I've used these since the original Measure Master Plus, which still is operating, and my only wish is they would add a percentage key to make it be an everyday calculator.
