The hobby of detecting metal using a metal detector is a lot of fun. We can find metal in the ground to a certain depth. We can find war relics, royal relics, objects buried by floods and landslides. Many even use ancient maps to search for the metal. They call it a treasure hunt (treasure hunter). Many have found ancient gold, ancient coins, silver coins, gold coins, tanks, pistols, rifles, bullets, bombs, and many other discoveries of royal relics, even relics of WW1 and WW2. Even the greatest treasure discoveries are made using metal detectors. There are metal detectors that are used on land, and there are halls that can be used underwater. Using a metal detector as a hobby is like a sport. We walk along hills, beaches, mountains. We can also enjoy many natural scenery. We can also find places of undiscovered history. Gold Nugget can also be detected using a metal detector.
