gold sound question

[croakersmoker78]

I found a 14k earing is a big hoop it was laying on the ground so I went over it with all metal and nothing.I tried all other modes and nothing not a peep.So my buddy used his E Trac and he had the same thing nothing any reason why his would be.I tested the earing it is gold but even if it was not it is still metal.Even putting it right on the coil it still would not pick it up.I have tried other gold and they register

Interesting, will have to try that on my wife's earrings

where was sensitivity setting and treshold setting set at?

If you complete the loops circuit by touching the two ends together and rescan, it should be able to read it. Now try burying it in the ground and rescan to see if it is picked up. The ground should complete the circuit and create a readable signal. I ran into this with a small broken silver ring. The Safari would not read it until I brought the broken ends together.

sensitivity 14 all metal hugh trash that is all I run all the time and it works great

I used to work for a company that produced coils and transformers. Open transfomers can handle more power but are less responsive to small signals. Closed cores saturate very easy but are very sensitive to small signals. Translate to any open loop you are detecting and the result is the open loop in effect does not provide a strong reflected signal so very hard to detect. Close the loop either metal to metal or metal to conductive mineralized ground and you are more likely to get a strong reflected signal. It did not mater if it was gold or silver just that it was open - I will say gold witch has lower conductivity will produce a weaker signal

A bent nail also gets more of a response than a straight one. Both have an inductance component at radio frequencies, the bent nail just has more. A completely curled up nail fools my detector for sure.

thank you
