All the years I used my Explorer, I found 1 18k gold ring. That's it. Since getting my Etrac, I see a lot of gold being found. Could some one please elaborate a little on what to look for or the possible sound. I realize that the conductive numbers very greatly due to different sizes and compositions of the rings, but what about the ferris numbers? Do they bounce or are they usually stable? I also realize you need to dig some junk to get the gold, but as much gold that is being found, not every pull tab is being dug to find them. I am a sound hunter, and then use the display as a reference only. Thanks for any advice in advance.
