It simply does what the name suggests. It finds anything with any metal in it up to a certain length beneath the earth's surface. Many fancy metal detectors will even tell you how deep down the metal object is so you can find it easier.
What Can I Find With a Metal Detector?
You could find rings, bracelets, necklaces, coins or anything metal. Depending on the brand of metal detector you buy and model it is you will get different results. Just ask or research to find out what kind would best suit you.
Other Uses
Schools everywhere are using metal detectors to help filter out violence. The metal detectors can very easily (for this is why they are used) detect a knife or gun. Police stations and Airports use them as well. Even some amusement parks such as ?Six Flags Fiesta Texas? use them, you buy your ticket then proceed to the park being stopped momentarily so the patrolmen can search any bags and have you walk through a metal detector.
As you can probably tell metal detectors are very useful not only to find that cherished earring but for our everyday safety and well being. This is a great invention that will be here for years to come.
So next time you loose that ring at the beach or you dime at the park remember there are ways to find you beloved object. Have Fun.
