I'm new to the VDI numbers. I have an ACE 350 that didn't have them. I am noticing with the AT MAX, that I will sometimes get a high-tone without a VDI number displayed. It is on deep targets (I'm guessing that they are deep) and sometimes when I try to pinpoint it, the AT MAX can't find the signal to pinpoint. Then as I swing the detector over the same spot, i pick up a high-tone again with no VDI displayed. Does this sound like I have sensitivity too high and the signal is a ghost? Do some deep targets not register a VDI number? Should I be digging these high-tone signals? Any feedback would be appreciated.
