Are you seeing all the great finds being posted with the ATpro/gold machines? Want to find some of that nice jewelry? Well it seems that most of the ATpro/gold users are hunting in either zero mode or with some iron discrimination. Really this is key to finding the jewelry. Your not going to get those surprise finds running in coin mode or even high coin only disc. This is not a new method of hunting. Sure if you have little time to hunt crank up the disc to cherry pick some cash and maybe that silver ring. But each time you go over an area keep reducing your disc to where you've cleaned out everything but the iron. I usually start out in zero mode digging everything but iron. Then as I get tired and sore I'll increase the disc to go back to cherry picking. You are missing most all the gold and other hidden goodies by always running in coin mode or higher. There is GOLD in the foil and tab notches! Like I said this isn't a new concept so it's mostly for the newbies. Get the most out of your machine - reduce your discrimination. Good hunting to all.
