Under optimum conditions, ie in spaces without disturbing possible light sources (which I have no idea as to when artificial light sources, unlike sunlight acting really disturbing) exceeds the device's specified specifications and therefore my expectations. In most cases the device compared to the ruler at most by + 1mm is next, whether now measured 2 or 4 meters. Often the value is true even exactly. Of course, this is Messerei be treated with caution, because the ruler is not exactly a precision instrument, and certainly not the tape measure, but the results show me the device replaces quite a ruler. The advantage of the inch rule is that the absolute value changed little, provided one is to 100% concentration in the measurement work in the location. Which brings us to the Repeatability of Bosch: Again, the value stabilized at 10 measurements of the same distance behind the other more than two values which are 1mm apart. With +/- 1.5mm could indeed expect three values. So is also the absolute accuracy in the green zone. Provided Bosch has used in this device an accurate and sufficient temperature compensated crystal time base, one these values remain intact for a long time under varying temperature conditions. A balance, therefore calibrating, then succeeds satisfactorily factory, so you do not have to expect too much variation in the accuracy of the devices delivered. However, I of course do not know how far that really is true and match my measured values with other devices from the series.
In addition to the specified accuracy and the functionality was important for my purchase decision. The device offers almost everything you'd expect in this price range. The rarely seen in this price range Min-Max function is really useful. Batteries takes the device harmless. However, I lack the backlight and a release button on the side of the device, which would facilitate the use in some situations. A dedicated data memory would be the device also to shame. What, however, does not fit, is the thread for tripod adapter only made of plastic, which is also the promise of professional standards of the device does not do justice. The Thread fits after all to the common camera tripods, so I'm going to do as a professional non diligent use of this feature. Well, the street price of the device is indeed well below the target price, so that can be get over all that. It remains to measure this unit to the competition and then it cuts to the bottom line but extraordinarily well off.
Anyway, I'm satisfied with the performance offered.
