I had a 5000D (series II I believe). The best place for that is in the closet or in the dumpster, where mine ended up. That is by far the worst top of the line White's machine ever produced, and I've had lots of them, ever since the Coinmaster V supreme days. It literally erased any chance at gold rings and nickles. I now have a DFX and let me tell you it will blow the socks off of that old unit. The depth and stability will amaze you. Pretty steep learning curve if you want the maximum out of it. I've found large cents at 12" in discriminate. Never any problems with minerals unless you are right on top of a mountain of trap rock. Then you need to be creative. But the root problem? Never. Things have come a long way in metal detecting since then. Just my opinion though. Check into Whites, Minelab and check the other forums to see what people are finding. The good brands smoke the other brands just by viewing the finds people have made. Good luck.
