Customer Reviews

Great Calculator,But !
I have been using my inchmate calculator for 10 years extensivly in my job as a mechanical designer. It is a great calculator and very fast. It helps me in adding and subtracting dimensions for layout of construction documents. The one I have does not have the rise, run, and slope features but square and square root keys acheive the same results just a little slower. The only improvement that the manufacturer could enhance for this calculator is the incorporation of sine, cosine, and tangent keys for trigonometric calculations. These features would win a five plus star rating for this already great calculator.

Throw away the paper....
How many times does it take to calculate where it make that CUT on the most expensive piece of wood in your collection? Exactly once! For years I have performed double, triple and sometimes many more checks on calculations for cuts on expensive, rare woods. The Sonin calculator has made calculation time short and accurate.

Easy to use and right on everytime. Now if I just get a tape measure that tells me when I measured wrong, I'm set!

Why guess when you can be sure?
I don't know about you but I have a tough time adding dimensions after a few hors on the job. This tool will save time and money and get you home a little sooner to your family!
