EMD V-2

-  This device produces an electro-magnetic field around its telescoping antenna

-  The EM field can be easily disturbed by anything that conducts electricity

-  Based on the proximity and strength of the electric field, three colored LEDs and one infrared LED (great for use with night vision cameras!) will light

-  An audible tone will also sound at the same time.  The tone will vary depending on the proximity and strength of the electric source

- The new styled face plate glows in the dark for easy location during an investigation

-  Runs on one 9 volt battery (not included)
