Very good device finds reliable water pipes and live wires. It is important to really like also otherwise mentioned, the "wiping technique" as indicated in the instructions. Was found when multiple run over the same place at the bit to fit the device the sensitivity further, so that the positioning is pretty good. Well, that can be marked directly on the wall through the "Search hole", even with a thick felt pen, eg Edding. For electricity connections, make absolutely sure that a consumer is connected and turned on. One star deduction for the two downer: No bag or box for storage, only a wrist strap, and in dark corners hide the LED light rings very so you will gebel ends while reading the display. Maybe I umbrellas from the anything else. (Tape or with a dark Edding once over it). Otherwise, for me a top unit, not to be compared with 20 euros DIY stuff. Recommendation.
