If we could do this kind of math in our heads, we'd be working for NASA, not cutting wood. This little gem will add, subtract, multiply, and divide yards, feet, inches, fractions, decimals, meters, centimeters, and millimeters and make you look really, really smart. We threw some astronomical calculations at it and got our answers in the time it took to push a button. Figuring board feet, squares, and cubics is not a problem, and this calculator will do area and volume as well. Stairs--perhaps the most intimidating of all construction projects--become nothing but a quick calculation. We thought it was a nice touch that a battery was included, and the user's guide is great, even for someone who lacks a degree in rocket science. We know how you like to do all your figuring problems in pencil all over scrap wood, but give this a spin. It'll be the least expensive and smallest power tool in your arsenal (it fits in a shirt pocket), but one of your best investments. --Kris Jensen-Van Heste

5.0 out of 5 stars Better than a framing square and the trusty ole Swanson, January 18, 2000

General contracting leads you into some real interesting situations - especially when you attempt to build round pegs into square holes. This handy gadget can do it for you without turning what little hair you have left further grey. Wish I had purchased it two years ago, rather than two months.

I laid out a complicated staircase in one attempt within 1/8" of my target. I can live with that anyday. Can't wait to build another house and cut the roof. Should be able to leave my "blue book" in the truck.

Was doing a house and the roof span was more than what the blue book had available. Went out and bought "The Ultimate Calculator" and have not used the blue book since. The instruction book is very user friendly. I use the calculator every chance I get which sometimes is not enough. I am even thinking about getting a second one for my lead carpenter. In my opinion, even at twice the price, it is still very much worth the money.

I have been building my own house now for the past 2 years and finally getting to the end. When I did my first set of stairs, I was petrified I would mess it up - is the angle right, will they feel right going up and then down, just how many risers do I need, anyway. There are plenty of rules about building stairs - the sum of 2 risers and 1 tread = 25 inches, and so on. With this hummer, put all that fancy stuff aside. Make the rise and run measurements, push the answer button, and start cutting. This is probably not a must-have item for most do-it-yourselfers, but if you have a big project and are doing your own design work, I would strongly recommend one. And, it fits in your pocket.
