Sonin DT210 Inchmate PRO Measurement Conversion Calculator

75% of reviews on Amazon.com give this product a positive rating.

Can't beat the accuracy and speed for various calculations needed. They show all functions "step by step" in simple format. I wish they had these instructions on line to print at larger scale for easier reading.

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...

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.
