Not for the competition but so proud so want to share. I had a crappy cheap metaldetectorish which I used on saturday in Hattula, near Hämeenlinna in Finland. 6-8 hours walked the fields and picked up metal trash. At last found that smaller ball which I assume is from a musket gun. They have found a lot of those on a nearby field. Then on sunday I gave my detector to one young kid whose parents just divorced and who was very fond of the machine when I let him search with it. Today bought a proper metal detector (had used that cheap crappy one for two years). Searched and walked ten meters when got a signal and found that 5cm diameter and 376g weight iron ball.
