Can pinpointer detecting thin chain?

[6666]

because I am considering to make a DIY kit

,

Please do, what is the circuit based on ?

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

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.

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

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

[Ism]

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

[Nupi]

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

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.

okey, I post today a video of my pointer and this week a video of my MD on which you can see that it is possible with a good MD detect a chain and even a link.

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.

OK. I will go to hunt that small chains! So what I have to do?

Get a pinpointer and crawl with it over several acres of land?

Or someone can advice a metal detector to find that small chain than pinpoint it using your great pinpointer?

I guess I better use a rake. At least it is much faster way to get that chain found:

a chain is detected by a detector on very massive part of it only, ie this maybe a lock on chain mainly. all link/rings are not add in all general mass for as a detector
reacts.

Small gold etc. chains have different weights, alloys and it depends if the whole metal is at one spot or the chain is spread out.

Low conductive coins, 5mm diameter, can be found at ca. 4-8cm depth. Most small chains contain much more metal.

The White's TRX hits thin chains pretty well.

i knocked up this circuit tonight and it works ok, did not have a buzzer though so triggered an led.
and its as good as any other pinpoiner(homemade) i've done.
does anyone here have a schematic for clicker audio stage, to add to it i want to have a play with this, i have a vco, and fixed tone but would really like a clicker for this thanks,
