9ct gold reading

Post by Dodo » Thu Apr 05, 2018 11:36 am

Hello all,

saw a video on FB with a guy testing a 10ct gold chain against his AT Pro and reading on machine was a strong 25-27, so i've done a test with my machine:
9ct gold -17-20 which i usually discriminate on machine and never dig...
14ct gold 67-70
18ct gold 68-70

any idea if its ok for the machine to give a scrap tone on 9ct gold?

Try the same experiment with a 9ct Ring

Chains are notoriously difficult for machines to see
If you imagine the whole piece of Gold in a chain is only joined and held together by the smallest of links touching each other
Where as a Ring is at least a solid chunk of gold
When you are right no one remembers; when you are wrong no one forgets

Shape
Size
Orientation
The ground
Depth
What it alloyed with
Ground balance
And probably some I have forgot about

All affect it's ID to some degree

Your machine sounds fine

right i have done some more ''research'' on this:

9ct gold ring - 27-42 reading
14ct gold 78-80 reading
18ct gold 78-80 reading
sovereign - constant 74

i have only buried the 9ct gold ring(because my wife caught me) and reading was 36 - 74.
i am amazed that it also managed to detect my 9ct gold chain but reading was as junk.

i was reading that some machines don't even see the chain so i am really impressed with it. ::g
