inchmate pro (Rating: 5.00)
Review : You cannot be this item for the price !! It is very simple to use. Takes all the guess work out of construction math. The time I saved on the last 2 sets of stair stringers alone more than paid for it.

Review : My two year old D210 InchMate Pro just died. Worked fine one day, sat on my workshop table overnight and wouldn't turn on the next day. Didn't drop it, no static discharge. A hard reset and a new battery didn't help. Dead.Pros: Will handle calculations in increments as small as 1/64 inch. Pretty nifty conversion between units, including yards, feet, inch decimal, inch fraction, and metric. Cons: Uses a special $3.00 CR2016 3V lithium battery. Inputting fractions is a bit tedious . If you input a fractional number and then input an integer or decimal number without also specifying the units of the second number (inch, meter, etc.) the calculator displays an error message that you cannot recover from. You have to clear everything and re-enter ALL your numbers over again.
