Howdy all. Just pulled the trigger on a Fisher F5. After making my eyes bleed researching, I got tired of it all and went for it. Was considering the F2 and the Garrett 250, then I noticed what seemed like quite a bit better unit for not a lot more money. I was wondering if someone could maybe give me some beginner tips. Maybe some initial settings on the unit? I'm going to be hunting coins and jewelry here in the burbs where I live, and then expanding out from there when I get a little more experience.
