Nice finds! The last gold ring I found was bouncing from a nickel and a pull tab on my ACE 250. Ever figure something out and couldn't explain it? Well, I did. I can tell a nickel from a pull tab most, I repeat most of the time with my ACE. But I can't explain exactly how. The tone is just a little different and after two years with the ACE I hardly look at the icons anymore, rather now I listen to the tones more than at first. Can slaw of the aluminum type always come in at the silver range on my ACE and my GTI 2500. But I have noticed a lot of people saying it comes in at the pull tab range. Can't figure out why unless it's just the difference between a Garret and other makes of detectors. And I have noticed that a gold ring on top of the ground gives a different tone than one that is buried. Why?? Beats me! Monty
