OK on solid walls but not plaster board and dry-lined,

I have wanted one of these for some time and when I chose this and it being Bosch I thought I was onto a winner. If your walls are solid then it will happily locate pipes and electrics, but on dry-lined and plasterboard partition walls then the red warning light comes on wherever you place it even where you know there are no pipes or wiring.
Disappointing but that's the problem with this for accuracy and was little help to me as I know the solid walls have no pipes/wiring and as it's an old place it was dry-lined and has partition walls.
