Omega, extech and several other known test equipment co make gauss meters. If I was going in the business of looking for high EMF I would buy one of those. No ghost hunters site! This same customer blocked the cell phone co from putting a cell tower blocks from her home (on a water tower) now when she makes a cell phone call the phone inches from her head must put out full power to reach the next tower instead of 1/3 the power to reach the water tower. There are people reading stuff on this here internet and believing every word.
