GQ EMF-390 good but can be better if further improvement
I really like GQ EMF-390 due to the following points: 1. It shows all kinds of EMF in one screen, so I can judge fast which one is in danger zone. 2. It analyzes very clearly the change of each signal in realtime. However, I would give it 5 stars if it can detect 360 degrees like a well known brand in EMF detector. Only if you point the device directly to the EMF source, it shows the signal, otherwise, the signal is quite weak. So if you want to detect a possibly dangerous EMF source, remember to scan it 360 degrees.
