I am using the Minelab Gold Monster 1000 here in Oahu. So far I have found 16 gold jewelry items. And yes, I do dig a lot of tin foil and many small pieces of other types of metal. Most of the time, I can operate in manual sensitivity level 9 or 10. In some areas, I do have to switch over to auto sensitivity + to be able to hunt. I do have high hopes for the Equinox 800 here.
