Got out for a 45 minute hunt the other day in between rain showers around a park shelter, not many good targets only found 2 quarters and 3 pennies however one of the quarters and a bottle cap that rang up as a good target had a trash target in the same hole, the bottle cap and a beaver tail pull tab and the quarter had a nail with it. Both targets sounded off with a clean solid beep (I was using the stock coil) gotta love how the Cibola is able to separate the good targets from the bad!
