Without knowing the exact makeup of the particular beach you'll be hunting, I can only give you the basics. I like Park 1 for dry sand and Beach 2 for wet and water. Sensitivity as high as it can remain stable. Iron bias on F2 @6 if bottle caps are a problem....lower if it's not. recovery speed @4 or so depending on chatter in the wet.....higher if you're around the fire rings and/or a target rich area. Horseshoe on so you can hear the iron. Pretty much dig everything that isn't a dead iron sound/number. If you have black sand, you may have to dig some real iffy scratchy signals mixed with iron tones. If a target disappears after the first scoop or two, dig deeper. Deep targets can do that. If you start finding several good target in an area, grid it. At an unknown beach, I like to zig zag from dry sand to surf. Once you have recovered a few targets, you can get an idea of where they are on the beach/slope/water. I then concentrate on that area by working parallel to the shore and try to follow the "treasure trough".
