Hay Nad,
[size=medium]Jabbo is right.
Gold fill is a type of gold plating.
Those metals vary in their conductivity.
You asked:
Does the gold content as purity have any effect on the ability of a detector to find it?
The answer,I believe is yes.
Gold is a low conductor and small gold jewelry can be very hard
to detect.
24k is pure gold. There for 12kd gold has 50% gold. 14k gold has
58.3% gold and 10k gold has 41.7% gold.
The lower karrats have different metals mixed in the gold. The
conductivity of those materials varies.
Gold can be like a bit of aluminum foil or it can hit like a penny,
depending on the size and content of the gold.
It takes patients to find gold.
I try to show my trash in my post so people can get an idea of
how many targets I recover. But when you look at it, it seems
to be less than I treally do dig.
There is somewhere in the neighborhood of 800 recoveries there.
Doesn't look like it though.
I'm gettin off the subject.........Sorry.........
