Some people ask if the metal detector can be “tricked”. Unless you try to pass a metal object through the circular detector or through some other subrosive action, the metal detector will do its job. The metal detector only uses its magnetic field to detect metals. Take your detector to do a spin test in your own backyard, more than once or twice.
You can place metal objects on the floor, such as coins, jewelry and other metal objects, and then place the detector on them to get an idea of the machine. You can also bury objects at different depths so that you can get used to the depth settings and what the alert sounds like the further away the object is underground. If you find any precious metal such as gold or silver on your next treasure hunt, be sure to exchange it for a refinery such as Manhattan Gold %26 Silver.
