I have a Bosch DMF 10 Zoom and in general I agree with the previous opinions about it.
Sometimes it is too sensitive and shows voltage where it is not, but I did not try to calibrate a few cm from the wall, I also did not know the way with the hand next to the sensor. For me, this detector indicates more precisely when the detected cable is loaded. I was hanging the lamp in the bathroom and drilled a hole 1.5-2 cm from the wire pointed to by the detector, I was a bit afraid, but the wire was not broken.
