Essentially, the EMS is a speaker that plays sound as a magnetic field, rather than playing it audibly. The reason behind this is that we find a lot of paranormal activity appears to react more with the introduction of EMF into the area, and this device will enable you to play music (eg: Trigger music, white noise, trigger sounds, etc), through an EMF. You will be able to play various songs and sounds, without polluting your EVP sessions, audio or video evidence.
The product is easy to use, and very affordable. The EMS also has strength control (much like the EM Pump), which lets you adjust the strength of the field.
Turn on the EMS.
Plug into your MP3 Player, iPod, etc. and play your choice of audio
