Best way to add feet and inches
This is the third Calculated Industries construction calculator I've owned. I've purchased them because, to my knowlege, they are the only calculator available with these functions. As a residential designer I find it incredibly usefull for day to day calculations without the tedious conversions required to use numeric calculators. The ability to convert metric equivalents is also quite handy. Finally the Trig functions make this a fully capable tool.

As for disadvantages, the number entry is a little tiresome, to enter 1'6 1/2" you must press: 1, feet, 6, inch, 1, /, 2. But the pay off is worth while to get results in appropraite units. The other limitations of the calculator are the number of digits displayed, 7 is the most you're allowed to enter and it will give you errors if your result is greater than 8 digits. Also the Calculator does round, 13/16 divided by 2 equals 7/16, but we're only talking 1/32, but I'd rather see a decimal result in that case.

All in all the calc is super handy and has nearly allowed me to forget how to count by twelves and sixteens. It's the best solution until we all go metric.

Best calculater for draftsman
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.

just what I was looking for
Does all that I need it to in a machine shop - a coworker bought one from a store and paid over $40 more!
