Photos: Got ghosts? You know who to call

Spirit hunting goes high tech.

When Sharon Leong conducts field work, she packs a digital camera, a thermometer and an electromagnetic field meter. She isn't a private detective or an electrician. Leong, a legal secretary by day, is an avid ghost hunter by night.

Ghost-hunting tech

With those gizmos and many others in tow, Leong treks to reputedly haunted homes, battlefields, bars and hotels, gathering what she thinks may be evidence of a world beyond this earthly one. The pursuit of ghostly evidence has been a popular pastime for centuries. Now, instead of Ouija boards, ghost hunters are increasingly turning to high tech gear to assist in their search.

Such ghost hunters rely upon digital equipment to document potential signs of hauntings. Cameras and voice recorders pick up eerie sights and sounds, while handheld gadgets measure electromagnetic radiation and odd drops in temperature. Jumpsuits like those from Ghostbusters are unnecessary, but pocket-laden cargo pants and fishing jackets are handy for stashing all of the gear.
