where can someone go to learn about the equipment used in ghosthunting and findout where to buy the equipment?
There are a lot of websites that explain and sell ghost hunting equipment. The most un-scam one that I've found is http://ww.paranormality.com/ghost_hunting_equipment.shtml
I'd be careful not to fall into a trap and get scammed though. It seems simple to make a machine that says it will find ghosts..
