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.

Be very careful
Very disappointed with this calculator. It is very handy for working out all your calculations and simple to use,but I just have it a week, I took it on the job site it fell of the top of my toolbox about 18 inches of a fall and when I opened it up the screen was shattered ,was not very happy, hoping amazon will refund me.My advice to anyone is be very careful with it.
