I went out for 2 hrs yesterday and I loved it (could have hunted for 8 hrs). This morning, wrists are and back are tender, haha. I got 14 pennies, 1 dime, a .22 bullet shell, and a huge iron bolt-looking thing. I was wondering what settings people are using to find things with their f2? What are some numbers that I should pay attention to for different items? many of the pennies that I dug looked like dimes etc. Will things that are deeper in the ground ID as something they are not? What about gold and silver? What should I notch out?
