Not always. But anyway I hope we get an answer about this if iron and gold falls in the same area with looping response. Great question Smudge.Smudge said:The other problem is that gold falls all over the place on the conductivity scale, which doesn't matters at all.
Hey Rob,do mean gold falls always from 0 and up?Rob (IL) said:Gold won't fall in the left quadrant. You can't tell if a VDI 19 is a nickel, tab, or gold ring on your search screen. The polar plot gives the same information. Both will show 22.5 Khz dominate, both will show the same Vdi. I have found all these with this number.
Use what works for you.

Rob (IL) said:[size=large]Any got a gold chain handy?[/size] See what you get in polar plot. I'm interested as I've never got a gold chain when using polar plot, that's because I don't use polar plot.

Not just for the thoughtful, intelligent answers, and there has been plenty of them!
But it seems when it comes to jewelry hunting, no matter how expensive the machine you hunt with, no matter what information it gives you, it all boils down to knock out the iron and then "dig it all".
