I get the idea that most are still trying to cull out the trash ahead of time, but you help yourself by digging some things that by all hints is probably trash. I know coin shooters are more interested in the coins...
After clearing the area you just hunted, the time to go would be asap. Right back over the area you cleaned. Relics are just as important to find as coins to me. Think of how many relics fall into the signal range as the trash. Think about those signals that range around the pull tabs...gold is hard to distinguish. I set up to knock out some iron and hate to do that. What makes me dig every time is the "ROUND" signals...

I know some of you know what I'm saying. There is a noticeably different sound to a round target regardless of material.
