I have noticed lately that sometimes when detecting (beach) the visual screen has full bars on the far right and left (+95)as if there was a target but it is constant, not fading out as I continue to sweep. I read something on the forum about VDI numbers being on a wheel and they are backed up to each other. That is confusing to me. Is this a situation where there is too much iron on the beach causing this? Sometimes along with this is the visual ID that there is a ring/foil and I pinpoint and dig and dig and dig and there is nothing there. Any XLTers have this problem?
