THAT is an awesome eye-opening article. That pretty much keeps my eye on the Golden a little longer. I thought that maybe I shouldn't even consider the Golden since my Royal appears to have something like an ED 160, since it won't pick up small pieces of foil. Now in reality, for the places I hunt, getting rid of the tiny foil satisfies, but I DID find several tiny gold rings with my Silver umax set at min-which will pick up tiny pieces of foil. To me, the Golden would actually REPLACE all my other machines because it would have the versatility of the min. disc., and I could still raise the low end disc if in too trashy areas(like my Royal), and STILL have the notch feature for the high trash areas. And since I have a nice Tesoro bag, I would only have to carry ONE detector on my bicycle with the upcoming warmer season. And with the tones, it seems to be like having FOUR detectors in one-coin and jewelry hunter's dream.
