MagneMeter EMF Meter AC Magnetic Fields Gaussmeter

I just received the product.It small and handy and easy to use.But be careful touching walls and hard materials ,you will sure scratch it.I passed under high frequency power lines and register a reading between 10-20 mG. I was terrified from my bed; when the air conditioner is running ,it reads between 10 to 20 mG on the place where I put my head to sleep.I know from this that the wires go through the wall is in middle of the room and at the same time at the middle of my bed.So,I have to stop the wall air conditioner or move the bed from this hotspot area.I recommend to everybody to have this kind of devices to do period check to their environments.I checked also my laptop and discover a strong EMF not only on the table but under it where my legs reside.
