stairs check, pitch check, volume check, doing it all in fractions check...just makes life easier even if you don't do rafters or loading equations...I bought the set that you get a CD with a compter program for your desktop also....lets me leave the calc in the truck so i have her with me when I need her

This thing has lots of helpful programs. If you want to roof a house, pour concrete, put in stairs it can be real helpful. Unfortunately for me, I was replacing a Construction Master Pro that I lost and the one feature that it doesn't have is the one I NEED the most. Trig functions (sine, cosine, tangent). It will do those functions automatically in its programs, but if you need those functions you need to upgrade to the next model.

I've tried out 3 or 4 of these and this is the best I've used. The cover design works really well, too. Worth the money.

Super Great Calculator, it makes my job a lot easier to get the right length of my rafters and hips...
It's very practical.... totally recommended 100%

Product is used by all detailers in our business of pre-fabbed steel buildings. Very good product.
