A metal detector that detects explosives in a yard is not only more effective than a metal wire to check on an apartment, but it also saves a lot of money, according to an article in the Detroit Free Press.
The metal detector can cost between $2,000 and $4,000 depending on the size and type of the house, the article said.
The equipment costs between $1,500 and $2.25 million, depending on size and style of the yard.
Metal detectors are used for several reasons, including protecting an apartment from burglars, preventing explosives from falling out of a window, and detecting any suspicious movement in a home, the newspaper said.
A metal-detector owner who lives in an apartment with an explosive in the attic could buy a $1 million metal detector and the owner could install one on his or her property, which is usually an attic or basement, the Free Press article said, adding that it can also detect a possible fire or fire alarm that is triggered by the presence of explosives.
Some people have used metal detectors to help them track down a lost pet, the paper said.
But metal detectors can also be dangerous if they are not properly calibrated, the report said.
One person who uses the metal detector at a house in the suburbs of Detroit said he would buy a metal device and install it in the garage if he needed it, the News-Gazette reported.
