I thought 180 could be set for zero discrimination and 120 when at minimum still blocked iron?
That's right, but what real advantage does ED180 have over ED165-170 when you're out detecting?

Probably none.
I have gotten really tiny nails with my Vac in all metal that it couldn't see with the disc all the way down.
Since I don't really hunt for tiny nails it is no big deal.
I bet all 180-160-120 ED units should pick up rings and coins fine in disc, maybe the thinnest, tiniest gold chains might be tough but a rare target to come across.
I got my Compadre for those, anyway.

It seems like my Silver microMax is 180. I was using it Sunday and when I rolled the disc up on copper pennies they dropped out. On my Vaq they seem to never drop out when at max disc
