Finally work a

Class device that with me even on my irregular wall plaster (classic hand plaster) electric cables on the cm indicating exactly how various tests on assembled by myself and as accurately known line courses provided. If you connect to another consumer or to turn on the light, so the unit does more easily.

In dry mode counter lathing is displayed correctly and safely under tongue and groove boards wall formwork. The same for joists of wood planks. A trial basis edgewise held on a wooden door leaf 18mm wooden board is exactly displayed correctly centered by the solid wood door panel. If I can anspaxen ...

The metal detector showed me to even accurately individual nails of 2cm deep Dielenvernagelung. He also finds the wooden floor in 10cm depth extending from the board surface heating copper tubes. Wandarmierung etc. are not a problem. However, there was no understandable false positive measurement signals in the immediate vicinity of radiators. This is described in the manual, and should be based on the electromagnetic properties of the radiator.
Not clear the detector comes with my tile, I probably made electromagnetic view (glazes) the wrong caught. But that is as described in the device specification.

While the GMS is now not a ground radar but with a little cream in the bulb and logical thinking about possible pipe runs / Elements of sub-structures and the limits of such metrology, you can narrow structures clean. What as some rumdilettieren on Youtube with the thing, I can not necessarily understand. But Manual should read help with something like that, although the GMS 120 is foolproof purely intuitive.

I can only say that I would like to have had the 120 GMS already years ago - would have saved me a lot of bad feeling when drilling. This little device is worth every penny - and still cheaper than 2 noname - China Plunder measuring iron for the same price, which indicate only nonsense. Best then thereby drilled by such a clever piggy bank a line, then saves correctly ... * g *
The GMS 120 I might have found the solution.
