Bosch D-Tect 120 Digital Wall Scanner is rated 2.3 out of 5 by 3.
Rated 5 out of 5 by from BOSCH D-TECT 120 In my case this detector works more than perfect, it detects 98 percent of all stuff what is behind the wall surface.

Rated 1 out of 5 by from False security is dangerous. Buying this scanner I was naively hoping that with perseverance I would learn how to use it despite lots of negative feedback seen. I think now that the only way to use it is to know know what is guaranteed to be behind the wall, floor, ceiling and then tracking it. If you start with an unknown surface then it will give you all sorts of false detection instances which both confuse and give false sense of knowledge. I've spent most part of the day tracking wires, copper and plastic pipes, joists in my own walls which I know precisely fore having put that stuff in myself. However, I think that is also that made me feel that I've finally found how to hold and how to move the scanner. The lack of manufacturing promotional videos for this scanner makes me think that they too did not manage to honestly detect things in at least 50% of cases. The manual is deceivingly simple but the usage is properly impossible. Finally took this scanner on a job and on the first task of looking for a joist I kept getting Live Wire readings. Finally when it settled and I've drilled a hole there was nothing but plasterboard and rockwool inside. No wires in the vicinity at all! The second hole was for a fan and I was now looking for "not finding" any joists, pipes or wires inside. Made a 10 cm hole and sure enough there was no joist, thankfully no rockwool but a standard twincore + earth lights wire loosely hang about 5 cm behind the plasterboard, quarter way across the 10 cm fan hole. If I had cut further that wire would have been hit 100% guaranteed. By-the-way, the light was ON and the wire was carrying that power. Good tool? Will go back to using the telephone tracking sensor which hums on live wires at the distance of 20-30 cm!!! Sure thing it will not find pipes or joists but nether will this Bosch deceptor. 5 stars for reliability of being deceitful!

Rated 1 out of 5 by from Madness Gives 99% false alarms in a all type of the walls where I know there are no any studs, wires, pipes, etc. Cant find any real live wires under the plasterboard where I got 4 x double socket and the light switch LOL. ONE real stud on all the wall !! In the box is ONLY adaptor and 4 x AA with the scanner plus manual; no lithium-ion battery & no "scanner complete with a dual power source" .......... ;)
