                    The Construction Master Pro Desktop version is designed to shut itself off after about 8-12 minutes of non-use.

                      So mine turned off after about 15 minutes not in use. You can also manually turn it off

                            This product has more options than my old hand held model had. The tilted display makes it very easy to read when inputting numbers and reduce glare from the overhead lights in the office place. Ideal for designers, engineers and estimators in the construction field. Even though I have only had a few weeks it works very well for my needs and exceeds all my expectations.

                            Great product. I work in the structural steel business and have used the same one for 11 years. Some of the numbers have worn off of the keypad. Just wish there was a solar powered version even though in the 11 years I've used one I think I've replace the batteries only 2 or 3 times.

                              Can't do a project without this calculator!
                              This calculator is unlike any I have used before, and has become an essential tool in every project I start. The calculator is larger than your typical calculator and will not fit in your pocket, but this calculator is packed with features and functions that speed up estimating and design time. Has a large display and large buttons making operation painless and simple. Comes with an instruction manual for typical operations. This calculator does it all! From miter angles to linear feat of foundation footings.

                              Performs all the construction calculation and conversions I need for residential renovations. Especially helps with takeoffs and estimating. Size of the unit is very comfortable during use, with a nice, clear display. Would recommend.
