A bit expensive for what it does,
This review is from: Bosch PDO Multi Digital Detector (DIY & Tools)
The tool is very sensitive to electric fields everywhere around. For instance, it will detect electricity whenever I touch a wire with my hands, or even when there are extensions lying around. The result is also dependent on the position of the instrument, and the reading for one point is often different if I come from the left or for the right (I am again talking about electric field readings). The metal sensing part is also difficult to use, because I don't understand what it measures. I can sometimes have >3cm of plaster, and the reading is saturated. In conclusion, this is a tool worth having, because it gives a rough idea of what dangers lie within the wall, **but** you can't really follow its readings "à la lettre" because there are only few places where you could drill.
