Hi all findsmall friends. I have a question. Sometimes hunting ill get a good signal. A strong repeatable 60-80's signal that in any direction sounds good. Ill pinpoint it and dig. After the plug is out no matter how many times I scan the hole or the plug itself I get no more signal. Ill try my garrett pinpointer in and out of the hole than scan with the deus again and nothing. This has happened a few times and I call it ghost signals. Any suggestions. Also I am a veteran hunter for many of years.
