They can cause harm when exposed to electromagnetic fields for long periods of time.

How do you combat EMFs?

Using the EMF reader, you can view your current location. You can then begin to gradually reduce your exposure to EMF.

What does a high reading on an EMF detector indicate?

The higher the reading, the stronger the EMF at the measurement point. This does not necessarily mean that there is a health risk, but it is good practice to minimize prolonged exposure to EMFs.

Why do EMF radiation meter readings keep fluctuating?

This is a normal phenomenon. EMF readings can be affected by changes in weather, source, distance, etc. In addition, the human body, as a conductor of EMF, can affect the readings.

Why doesn't my EMF tester detect EMF near electrical outlets?

This may be due to the presence of shielding effects; frequency ranges that may not include specific frequencies near the outlet; weak magnetic fields, diminishing electromagnetic field strength with distance, and improperly oriented testers.

Screen failed after a few weeks

Sadly the screen failed after a couple of weeks and I found that the battery didn't last very long, a few hours at best, so I returned it.
