Some may believe in life after death, some might not believe in such hocus things. I submit a site that does not give absolute evidence to such a claim, you might have even heard of it.
AA-EVP or The American Association of Electronic Voice Phenomena. The individuals who are part of this organization could be what you call ghost hunters. EVP is a method of recording white noise (common background noise), in order for the dead to interupt the sound waves before it reaches the microphone, causing unearthly words to appear. There is also another method that they use called ITC or Instrumental TransCommunication, which uses electronic equipment (TV's, monitor's, camera's) to actually capture the image of the dead.
I have and still try EVP experiments on occasion as a hobby. So far I have yet to receive any messages from the 'otherside', or maybe the reason is because I use my computer's microphone (they suggest you buy an personal recorder), or that no ghost seems to want to come within a 1000 feet of me. :P

Even if your not a believer of the paranormal, check it out anyways. Some of their examples are spooky.
