Building your own metal detector is fun and educational. While building a traditional metal detector may require a kit (or in depth knowledge of electrical circuits), you can create simpler versions with household devices. The fastest way to detect metals is to use the magnet field on your smartphone. A more well known method is to use a calculator and a radio to make a metal detector. | Building your own metal detector is fun and educational.

#Test the metal detector. Once you have assembled your metal detector, you should test it. Put down different metals on the floor and pass the coil over them. If the coil detects the metals, then you are ready to take your new metal detector out and start looking for treasures.<ref name="rf3" /> | #Test the metal detector.
