Red circle with a dot for loose surface, down to 1-3 ft deep coins or old stuff metallic. Green circle with a dot, archaeological targets or sites including non-metallic stuff such as Indian flints, old foundation stones, glass, pottery, caves, etc. This search did not include gold/silver veins or placer gold deposits, if needed I can do a separate marked map. The large green circle with red, something about it different there (at least a deeper depth) on the markings, than what was mentioned above. Also far right red circle large dot, stuff is deeper.
