Anyone have any advise as how to distinguish bobbie pins from small gold chains? Last water hunt I dug at least 30 bobbie pins hoping to get a chain. I did find 3 junk chains. Still in quest of a nice chain or small thin gold ring. I have found 2 silver & gold rings. Any help would be appreciated.I thought the water hunting booksI read talked about narrow small sounds for gold jewelry.

Rarysgaard, what machine you are using to search for small gold chains?

Hi

Very few units to take the gold chains. no medal
Obtained with the SSV3
on his first
6.9 gr / 14K

Goldquest SSV3 and Goldscan 5C

I am using the detector pro head hunter PI machine.

the pulse delay is 15 us head hunter
too, for very thin chains
be better on 10 us

Here is an extract from instruction manual for HEADHUNTER PULSE (PI) detector:
"FREQ (Frequency) Control
This is a very unique control that is able to re-tune the
sensitivity of the HEADHUNTER PULSE (PI) detector to be
responsive to selected metals with out losing its depth
toward the selected metal. Unlike other PI detectors,
turning the frequency control back from the higher
frequency position will not result in a loss of depth for the
detector.
In its more clockwise positions, the detector will be tuned
most sensitive toward low conductive metals such as smallgold jewelry.
As one rotates the control, the detector retunes
itself toward different metals gold jewelry toward
the higher frequency settings; iron toward the lower
frequency settings. (Note: Iron can not be tuned out with
a PI detector.)
It is recommended that the new user set different target
items on the ground and pass the coil over them getting
acquainted with the response the detector makes when
locating them. Adjust the frequency control for best
response to each metal test item, making note of where
the best response position is on the frequency control.
This knowledge will help you in identifying buried items.
One needs to keep in mind that a lot of different metals
respond the same way electrically to a detector. Aluminum
covers a wide range of responses from low conductive
jewelry to large coins. Gold and gold jewelry covers a wide
detecting response range depending on its alloy make up.
As in all metal detecting ID'ing and discrimination, it is not
exact. Metals do not always react the same way each time
when excited by a transmitted signal of a metal detector."
