Detects AC magnetic fields like an EMF meter and converts them to the equivalent sound. You can easily hear the different frequencies and distinguish the strength of the fields. Sound is loud enough that you could even put eSmog Scout in your shirt pocket and still easily hear it, leaving your hands free. Helps find source of a field quickly.
Simple to operate!
Set button to EMF: Red/Green LED indicates when field is too strong, plus built in speaker give clear audio tone which corresponds to frequency and intensity of the field. 1-Axis detection of AC magnetic fields from 20 to 10,000 Hz. Touch the finger pad and your body acts as an antenna to pick up electric fields as well.
Additional feature: Set button to flicker: LED display indicates frequency of flicker and % of flicker relative to the light intensity.
