If not, what equipment would you suggest?

Also, how would you go about collecting information on a ‘site’ in a scientific way in order to weed out the BS from other unexplained occurrences?
Thanks for the answers everyone, but I’m looking for more details then that. =) All the ghost hunting sites I’ve been too seem to be just a bunch of people telling ghost stories around a camp fire. I want to dig deeper then that. more Science, and less ‘Ghost Story’ you know?

You know? I do watch that show. However, it’s just not as ‘interesting’ to me as ‘most haunted’ on the travel channel. TAPS comes across to me more like a ‘soap opera’ then a ghost hunting show. Though it does seem more realistic. Just to much drama with TAPS.. LOL
