If you can use a standard calculator you can use this tool.

It cuts calculating time at least in half and without mistakes (unless you input it incorrectly).

Now if I just get a tape measure that tells me when I measured wrong, I'm set!

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.

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!

I am a 35 year experienced builder and have owned both the Construction Master and Sonin Calculators. I liked the Sonin better because it's easier to use and more suited for problem solve a builder experiences. But I have noticed some people having problems when the Sonin displays the memory error message, they think it broke because they can't get it to escape from that. All you have to do is press the clear button twice or 2 times then turn it off and back on, or just use a pen and press reset on the back of the calculator. It tells you how to do that in the instruction booklet but I guess a lot of people don't like to read.

Coming from a country that uses Metric, I purchased this as some of my woodworking plans come in Imperial measurement, and its handy to have a calculator that can convert between the two measurement types on the fly. This calculator will do that just fine. The only gripe is that entry and conversion could perhaps be a little more intuitive. It is a bit fiddly in some regards but it does get the job done.

It takes a few minutes to get used to the procedure for entering measurements in this construction calculator, but once you get the knack and start using it, you'll wish you had it all along.

It's perfect for the general builder on site or for home improvement projects. Sure it won't do elaborate trigonometric calculations. But that's the kind of thing you figure out when you're at the computer at home doing the head-scratching work. On site you just want to know how long to cut the board. And you don't want to have to cut it twice because you added or subtracted a fraction wrong.

I didn't realize what a must-have thing this calculator had become until I thought I had lost mine. I was getting ready to draw some shed plans, and there was no way I was going to start until I found the Inchmate. After searching for a while I gave up and ordered a new one.

Of course my old one turned up a day later. But that's okay. Now I have a backup and I'm glad to have it.

Good construction Calutator at a good price. I know a person who paid over $50 for a construction calculator at Home Depot. I don't know what extra special functions that one has over mine but we do the same job and my calculator handles it fine. And it does the job just as fast. My only complaint is that you have to hold the function button in order to save a value to memory. It's just a little thing that shouldn't bother most people. I like the sliding protective case. And there's a place for you to write your name on the case so you can spot yours from a distance.

I am a general contractor and I have used the inch mate primarily for calculating diagonal dimensions for foundations, rafters, etc. It is a little difficult to get used to but any initial inconvenience is not only inconsequential but well worth it to get used to this little gem. It's so difficult to calculate foot and inch diagonals with a standard calculator, but the inch mate makes it a breeze. I'm buying more to give my lumber salesman and my sub contractors.
