Leaps of Consciousness

High-quality hand-held meters will tell you what you need to know.

There are many comparison sites to advise which ones to get.

I have an Acousticom 2 for EMF from wifi, phone masts, phones, etc and a PF5 Pocket Power Meter for Electrical and Magnetic fields from electrical cables. Both are from EMFields Solutions.

Both can show signal strength in light and sounds. They are made in the UK and widely used by professionals.

I comprehend the Trifield meters are also popular.
