Well, it’s more of a ‘things will stay as they are’ talk than a ‘you will do amazing discoveries’ talk.
This counts for most detectors that have a visual ID screen.
Testing several rings and items on the XP Deus to see which targed ID they give. I guess the lesson is: the more you dig, the more you can find. I just find that almost all items that have a lower ID turn out to be foil and lead, but I will just keep digging, I guess, not to miss out on the nice silver things. Or small gold on the beach and in the playground (mostly foil though).
Also, a Bad ID might turn into a better ID once you shovel out a bit of the soil.
I used 18khz here. The ID differs a bit depending on the freq you use.
