Everybody loves a treasure hunt, and the Explore One Metal Detector is easy-to-use and will have your junior explorer sweeping for hidden valuables in no time. Different tones will identify various precious metals buried up to 6 inches, and LED lights allow for low light or nighttime searching. A metal detector contains a coil of wire (wrapped around the circular head at the end of the handle) known as the transmitter coil. When electricity flows through the coil, a magnetic field is created all around it. As you sweep the detector over the ground, you make the magnetic field move around too. If you move the detector over a metal object, the moving magnetic field affects the atoms inside the metal. In fact, it changes the way the electrons (tiny particles "orbiting" around those atoms) move. Now if we have a changing magnetic field in the metal, the ghost of James Clerk Maxwell tells us we must also have an electric current moving in there too. In other words, the metal detector creates (or "induces") some electrical activity in the metal. But then Maxwell tells us something else interesting too: if we have electricity moving in a piece of metal, it must create some magnetism as well. So, when you move a metal detector over a piece of metal, the magnetic field coming from the detector causes another magnetic field to appear around the metal.
- Detects objects buried up to 6 inches below the surface.
- Water resistant base lets user search puddles and other moist areas.
- Height is adjustable.
- LED lights make it easier to search in low-light situations.
