Rated 1 out of 5 by from Waste of time Bought this today to check some cable positions before drilling. Utterly useless! To start with, the label covering the LED was not actually stuck to the body, just thrown in the packet I assume. Put in a battery and tried finding cables I knew were there but it does nothing. Checked against the lead to my kettle and will pick it up if placed directly against the cable, so not a lot of good for wiring buried in plaster. When tried on metal setting it would pick up the metal edging to the plaster from 3 inches away or not at all, neither would it pick up the wiring on this setting.

Rated 5 out of 5 by from I've owned (and thrown away) various detectors over the years, but this one actually works very well. I also like the fact that it has variable sensitivity and is reasonably priced. I am very pleased with it...

Rated 1 out of 5 by from Its a bit rubbish as it singularly failed to work when we put a battery in it ..... apparently everything it pointed to either carried a voltage or was metal. Utterly dissapointed

I bought one awhile back and need to know the best way to use it for buried pipes and wiring please. Do I back volumeoff to eliminate sound before using it to test ? Model is MD-98. Thanks

Asked by: Bren
Yes, you would increase sensitivity to the point the detector activates (while away from a metal source) and then roll back until the point the sound and LED flashes stop before searching. For a fuller description, please find below a link to a copy of the user manual which details the setup instructions for both metal and voltage searching.

Is this only for stud walls or can it b used on solid walls 2

Asked by: libby668
This would depend on how thick the walls are, if they are up to around 3 inches this would be suitable.
