I was allowed to test the Bosch PMD 7 extensively today. After 8 drilled holes (45mm deep) I met with the drill twice involuntarily the reinforcing steel. The PMD 7 had shown each green. Luckily there was no power line. Power lines can therefore not detect. In the field of light switches and outlets of this part is still connected to a power line, if the line a few centimeters runs in the wall, is dead trousers for the device. In the open air the unit capable of a cable can be seen (from a powered-on hanging lamp) to just 5 cm, in the wall quickly goes nothing surprising. If stroked with the 7 PMD across the wall, to show the progression of the line, the part will beep almost ohnen interruption. If you then resting, the beeping stops often. It seems as if they have found a line and takes the PMD 7 away from the place, and then place it right there again, it often happens that he then green shows, or even the exact opposite behavior can be observed. I have been drilled, where the device said to have detected metal: no metal in the hole! Twice I came to the reinforcing steel, as the unit had released the hole. My wife said soberly: "to the device you need additionally a polygraph." This idea I liked, but the matching polygraph was not included. Therefore, I think: cubes faster! Conclusion: Factory Fresh bulky!
