Content: This is the forth calculator like this I have bought. One a different brand and the other 2 have been from Calculated Industries (Maker of the construction master pro) and this has been the best one so far.

I love it's ability to handle feet and inches, built in trig (pich/rise/run calculation) that way I don't have to remember the sign cosign and tangent and how to use them. Built in circular calculations, ability to convert between metric and imperial (feet and in).

There are several other functions that are cool, but I do not use, like the ability to figure stairs, figure a compound miter, ex.

If you are looking for a calculator for a job site, or as a draftsman in my opinion you can not go wrong with this one.
Summary: Best calculater for draftsman

Content: I am a structural steel detailer. This involves creating detailed CAD drawings of steel, using Architect's and Engineer's drawings as a basis. I find this calculator an extremely valuable tool, allowing me to perform mathematical functions on fractional dimensions without the need to convert back and forth from decimal form. This particular model also includes trig functions which come in handy occasionally. I gave it four stars instead of five only because I wear out the keypad on one every two years or so. Wish they lasted a little longer....but this IS a well made product and highly recommended.
Summary: Must-Have Tool...
