It does everything my trusty GP extreme does and more. Smoother threshold... Cleaner signal response... Better head-saver when going over large targets.. Even though I did not dig any deep targets on this trip, I could tell that this machine does have the same capabilities. Is it worth it to upgrade to the GP 3000? For me, as a nugget hunter, I want every advantage I can get. And if I am going to be out there doing this, then I want the best machine for the situation at hand. In my opinion that is the new GP 3000 for the size of gold I am after and the areas I detect. Gerry M - Idaho, USA
