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. Tried to search information and closest comes a ball they used to stuck 5-6 pieces in a clothesbag and shoot it with a cannon. That would date it to around 1600-1700. Still have to try to find more info before saying for sure. But Garret Ace 300i seems a very good detector and I'm glad I finally decided to put money on a proper detector.

Edit: Darn. My wife says the ball is a trailer knob ffrom an old Datsun, one friend that it is a dinosaur poo, and one friend gave the best possible explanation: hight knob they drill to rocky hills abnd paint red. Really have to find out somehow.
