Found an "EMF Array" Picture

I was doing an image search for EMF detectors for my "paranormal hunter's bag-o-props" and came across this pic titled "emf array." I dunno' if it is genuine or bogus, but it looks neat. Anyone know where a fellow can get something similar in kit form or completed? Obviously the plastic "stand" is a cheep picture frame...

 

I suppose I could buy an EMF with the LED's, gut it, and repackage it like the one in this pic.... or goose it up like the one on Supernatural.

Anyone own or use a real EMF detector? Does it chirp or make noise when you use it? Or is that bogus TV stuff?

 

those as pictured were available on ebay a long long time ago...$20 or so i think....just like that, minus the plastic stand....

 

I have the same model they use on Most Haunted. Its very cool. It makes the same "Chirp" as the tv show. I wish I had the guts to go and try it out somewhere scary. :confused
