Sorry for the delay in getting back on here been dealing with family health issues.
I did do a factory reset on it, and auto balanced it
I tried the park 2 setting and it would not pick it up at all the gold 2 setting picks it up but the number goes from 1,2,3,4,5,6,8,10,11 and when i lock in 4 or 5 the detector is like detecting phantom things it will show something is right there, dig, sift through even take any rocks found out run it past and nothing and then check again and now the focus mode shows it several inches away from where it previously showed.
It picks up at the earring at currently between 1 - 1.5 inches at my best guess
here is the detector running over the earring
