Can pinpointer detecting thin chain?

[Waikiki_Sweep]

Yes sure. Cooper, silver, iron chains can be found even if they are relatively small. But to gold chains without heavy lock, ring or medallion on it at least smaller 4 mm. wide we have so say bye bye.
May be some $4000 nugget detector can see gold chain 3.5mm or 3 mm. or even 2.95 mm. wide. I have no one and can't test.
I guess using such nugget detector to look for small gold chains first let you find all bits of aluminum foil starting 2-3mm in diameter.

The video is ready. It is not well made but you can see how the pinpointer does. The pinpointer needs to be further improved.

Liked the video. Keep us posted, you have grabbed my interested.

Hi Nupi - good effort - like the techniques in the video.


your 1/2" distance is written as 1 1/2 could be misleading for some.


What design is that? S

[sinclairuser]

it think its this one
iv'e built it and it has potential(as much as any of these home spun pinpointers), as i said before i'd really like a clicker audio stage for this, if anybody has one.
thanks ally

Ism:
Thank you for your interest and I will keep you informed.


golfnut:
Thank golfnut you're right. I see now that the marking of the
1-1/2 is not right to. I have 2-1/2.
but I want to mislead anyone. Sory for
the mistakes, I was too hasty,
On the circuit, I can not say as much because I am considering
to make a DIY kit, so that with little effort, most people can build a Proper
pinpointer.

Great pinpointer!!!! Nugget hunters will kill for one. How it behaves in real ground?

,

Please do, what is the circuit based on ?

I agree with you, we do not seek into the air, but in the ground.
I make this week a video with wet beach sand and clay soil. I know the result.
I can only tell you this: you'll be amazed.

[Nupi]

Sure it is possible. Question is: how thin chain, what is its bigger part and how it is made. If it is made so that it act as a thin wire then it is not a real thin chain.

Hi WM6, I agree with you that determines how the chain is made
but I think the chain shown on the video can really call a thin chain
without closure or whatever.

The

pinpointer soil test is ready. I'm curious what you think of it. Now I expect that I will be reappointed chief of Carl at White's Electronics

Try Minelab. They already have a few PhDs for your assistance.

[Nupi]

I'll consider it. Thanks.
