No Crazy, the CZ's will do much better because they can be run in "no notch" or in true all-metal, and they do not see the smaller than a thumbtack iron junk easily either, but the CZ3D will double as a gold nugget hunter, but the other CZ's will not.. The AT pro will work better in a more (recent) park, but only because less iron is in it. Where there is a lot of iron junk, the AT Pro will drive a person nearly nuts with all its noise. Not so with a CZ or Minelab Sovereign. No notch mode (AKA all-metal) makes a CZ find (all) relics dime-sized and bigger very easily, while avoiding the small half thumbtack sized iron. They are very unique in that regard, designed that way, and that's why people don't want to sell them. Again, the AT Pro is a poor relic hunter, it wasn't intended for that use. At 15 Khz, it is mostly an all-around detector, the CZ's with two frequencies are designed specifically for searching old home sites, battlefields, and salt beaches as are their sisters the CZ20 and CZ 21. The CZ's are all made to find old brass, copper, and bronze very deep and very loud and KellyCo even says that in their Ads. Those three metals were dominant and contingent of, with, and for the Civil War era.
