Class detector

I have this detector now say for almost 3 weeks in use and needs, he does his thing !!!
I have searched the wall as a test and drilled at swings in the wall. Has hingehauen everything. Sure there are tolerances of 1-2 cm determined, but that is absolutely justifiable for the price!
Now and then he shows power lines as a non-magnetic metal, which is absolutely right !!! What kind of world copper is ferromagnetic ??
If a consumer is connected with enough load on the cable, and the magnetic field at the sensor is moved strong enough and the device displays a conducting wire.
You also have to say that one can estimate to 9095% if the non-magnetic deflection of the scale of a power cord comes or not. The fact that the device can not be set 120 as in the GMS on the ground, and therefore all detected what it may, it is everything. The interpretation of the measurement results has to do yet, man.
The guide also explains how to deal with the fine scale. only by repeatedly drive back and forth over the affected area, this enabled.
So far, everything fine. The only Wallscanner I can recommend. Even friends who have lent him, had no problems.

I can not understand the negative ratings partially. Interpretation of the measurement results must halt man. So it will remain so for a long time, especially in this low price.

Oh, there is no case to do so. Only the device, battery and a hand strap + manual (you should really even read!) Were loose, but well cushioned in the packaging.

And in those where the device spins. Just go into the fresh air and recalibrate. Has helped me wonder;)

Should I take a gas, water and power line yet, I'll write it here.
