ES Device

 

The ES device is a piece of equipment that converts audio voice recordings or music into a magnetic field frequency.  You can even pump white noise from it to generate a possible response.  It simply plugs into any device that has a stereo jack such as a radio or even an I-pod.  You can place this device next to a recorder to see if an entity responds.  It is great for situations where an investigator wishes to play trigger music or sounds specific to each case. 

 

IGSS recently used this device with an I-Pod and played basic 30's and 40's music for a case that had reported ghostly activity from members of Al Capone's crowd.  This device is an excellent tool!
