First off, I've read your other posts, STOP WORRYING about which one will find the most nuggets. If you wanted a machine Primarily/Geared towards Gold then you should have bought the AT Gold, but if you wanted a machine for coins, relics and still gold then the AT Pro is just fine.
The only difference is 3kHz, which really isn't all that much if you see all the other detectors out there going into mass double 300-600kHz's.
SO, with that being said. The AT Gold WILL find lil baby tiny pickers. The AT Pro, unless your running on Max Sens and the ground conditions are alright won't be able to find the lil baby ricey gold. I HAVE seen pictures and read stories of "pickers" being found using the AT Pro, so I'm sure it's entirely possible after you've learned your ATP sounds well.
The ATP and ATG are MEANT TO FIND GOLD.
The ATG is NOT MEANT FOR SALTWATER, TOO MUCH INTERFERANCE. With you being in New Jersey and close to ocean I'd say F yes friend, GREAT choice on the ATP above the ATG.
Change your detector on here btw, you still have "open for ideas what to buy."
