I always think of them as one step closer to a gold, with each tab you dig you get closer to that gold item, If you go hunt and dig 27 pull tabs then say man I am sick of tabs and then stop digging them you have effectivly ruled out your shot for gold, There are ways to improve your chances but you will never eliminate the pull tab curse, I dig what I call some ''warm up junk'' If the first five tabs all read the same I will rule out that TID, I found a nice 18k band two weeks ago, the sound was nearly identical to a pull tab, but the TID was 2 numbers higher than the 30 plus tabs I had previously dug, Just keep digging them or you will always have that ''gee I wonder if I missed a nice ring feeling'' .....Steves advice is very sound , if you have any intention of going back to a spot its best to start clearing it out, without the presence of tabs and foil based junk it makes deeper coins a lot easier to hear, I have a spot that didnt start to produce ANY deep coins until the third trip and after clearing out no less than 125 tabs and newer clad ..........good luck
