E.Smog Scout LUX

Acoustic & Optical Detection of electromagnetic pollution with light sensor!!!
Great for home use finding emf or for paranormal investigations.
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.
Scout has a 3.5 mm mono headset jack for covert listening, or connect to a DMM, oscilloscope, or spectrum analyzer for frequency and relative field strength data.
Could even be connected to a voice recorder for EVP analysis. Easy 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.
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.
Other feature: Set button to flicker: LED display indicates frequency of flicker and % of flicker relative to the light intensity. Dimensions: 63mm (W) X 118mm (L) X 20mm(D), fits nicely in the hand. Powered by: 9V battery (included), 24 month warranty.

Gauss Master EMF Meter
This is a very popular EMF meter among ghost hunters. It is seen quite often on various TV programs such as Most Haunted.
How this model works:
The meter is activated through one push on the button and switches itself off automatically after about 2 minutes. Then you push the button again.
The meter can be read in two different scales. From 0 to 10 milliGauss (mG), which is the most common way of using the meter. If you want to measure very subtle EMFs, then hold the button pressed and measure EMFs between 0 to 1 mG.
The meter creates a buzzing sound starting at 2 mG. The buzz gradually changes to a higher and higher pitch. Sound can not be turned off or adjusted in volume (for a quiet EMF meter - see our other listing for the K-II EMF meter).
There is no light that lights up the scale for easy viewing in the dark (for a meter that you can easily view the readings in the dark - see our other listing for the K-II EMF meter).
As always: Man made EMFs will almost infallible create a steady reading. Paranormal activity is erratic and will cause the needle to suddenly spike. Often repeatedly.
