Hi, look for a metal detector, I will help https://detecthistory.com/ The metal detector is a rather complicated device, which is necessary for searching for metal underground. Beginners mistakenly think that this device is needed only for some important find in the form of treasure, precious coins, and so on. But in fact, this tool should be treated more responsibly. Thanks to him, you can find a lot of interesting gizmos, because under the ground they are kept a great many. I use this pinpointer one season and the purchase of this device has fully justified itself.
