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.

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.
