I do rely greatly on your products and we have many contractor who do also. I have a Construction Master Pro sitting next to my key board at all times, a Construction Master Pro DT Printer and Scale Master Classic on my main desk and a Trig Plus II and Scale Master II in my briefcase. Now that I have a Droid X I'll be loading your app on it also. I don't understand how a true contractor lives without your products. I feel it's products like yours that make the difference between a Professional Quality Contractor and a wood butcher.

I have been using the scalemaster for over 15 years. I find it saves me a great deal of time in doing material lists of blueprints. I would be lost without it!

Antler Measurements 4 out of 5.0
User: from Potomac, MD
User Rating: ★ ★ ★ ★
I'm a deer hunter and I thought that this would be a nice device to have to measure antlers. The problem is that I measured the length of a standard sheet of paper for a calibration check and the device will only read in whole inches and not half inches.
