The videos are no longer available. I'm having trouble discriminating trash after following all the guidelines posted. I went to the park the other day and the detector went crazy with signals and producing a lot of similar sounds to that of silver. After digging up multiple trash items I figured I had some more learning to do, but all forums say the same thing. I'm just trying to find the missing piece here because after lowering the ground balance to 2-3 and switching to high conductors I'm still getting really strong signals from trash. I appreciate your help
