Curious why the Equinox chart page 31 user manual shows diamond rings/jewelry/gold to be high conductive and most likely copper?

OK, not exactly what they may be saying, but the "ring with setting" icon = jewelry = gold is shown as a high conductor, and in a row below it, high conductive aligns with copper, and gold is grouped with aluminum under low conductive. I wish aluminum WAS low conductive, but on most detectors I use, it's right in there with brass (buttons), big lead, and many coins. Shouldn't the ring icon be in low conductive and a coke can be where the ring icon is? Did Minelab get this wrong, or is it me?

Does an archeologist argue with a plow? A bureaucrat with a bulldozer?

They got it (mostly) wrong. Someone didn't proof read it. While it's possible large high kt gold rings such as 20-24K pure can read penny those are very few and far between. Like 1 in a hundred in my experience.

S'funny too how the copper Euro coins, the 1c, 2c, & 5c read 2, 5 & 12
These are copper coated with steel innards and [should read] - minus numbers?

That chart [may have] been drawn up very early into the testing process?
Either way, charts showing TID's can be notoriously way off!!!

I spent [a lot] of time bench testing all manner of coins & targets on the 'Quattro', years ago and if you have Andy's 'Quattro Safari' book, Pages 52-53, you'll see LOTS of targets don't read as you'd expect and MANY mimic each other with the exact same TID's - even shapes that don't conform i.e. Round, long, jagged trashy aluminum.

Not unless the women has hands like a gorilla.....probably a typo of sorts......foil to high nickle is more like it...
