I've already posted my frustrations with the Beach Hunter ID. So many false signals in fresh water, at least at the beaches of Lake Erie. This is frustrating because these beaches are packed in the summer, has to be lots of rings. Should I sell it? About 9 months old. What would be a fair trade in value? I know the Excal 2 is the machine to have in these onditions, at least i think. Desmond in Buffalo.
