Gold nuggets/treasure detecting: partnership

Here is some more to go with the circuits.

Oh blush! I  did not do anything. 

I was thinking, whatever you build, try to get 2 sizes of coils: do the surface, once over, with a small coil.... 15cm to 20cm; then go over it all, again with about a 30cm coil. The small coil will get small, shallow stuff while the bigger coil will get deeper (not so good for small, shallow) even large stuff.

Take a plastic pail and a small scoop or trowel, or foxhole shovel; scoop it into a pan until the detector does not indicate anything then go to the next one. Do this all day, then wash/pan out the nuggets, in the late afternoon, while you sill have good light. 

You may want to limit the detecting and scooping to about 6 or 7 hours, to have enough good light left. Here, in summer, we have good light from 5 AM to 9 PM.... (but cold in early morning) just think what you can do with 16 hours of sunlight (I am about 55 degrees north and you are probably about 15 degrees north.... big difference.) 

There may be a problem with both size coils and that is what is called "hot rocks." Hot rocks  act like metal, some may even have metal, in them but usually not. 

Hang off on the building a detector, there may be something good coming, I am working on a Pulse Induction idea and one of the other forum members is planning to build a BFO that has been redesigned..... if we can work the wrinkles out of it.... he is just learning electronics but has some impressive software. He is analyzing the circuit and has had some problems with the software using the correct components.... it will work out. 

If he can get it to function, I/we will send you and your friend an improved diagram. The biggest problem, for you will be making the printed circuit board and getting the components..... got any old TV's you can rip apart, for parts?? Meanwhile, I should get off of my "adipose concretion" and do some building, myself. (adipose concretion.... adipose = fat; concretion = an accumulation of hard material; together = fat a-s. ) 

I need to be out finding my own nuggets!

Your country sounds similar to Brazil, in South America: lots of poor people, working in very bad mining conditions, for a few dollars, peso or Cruzieros.... what ever it may be.

My grandfather, in the early 1900's, had a small coal mine, about 100 mile (160km) from here, and there were lots of other miners in the same area. They mined from a creek through a point of land, right through into a river valley... right through a huge hill! Its not good.

Using a metal detector will not make a lot of difference, because there will still be people who will do things the old way, but it may help a few from dieing in cave-ins. I have worked underground, but in very controlled conditions, AND I had to have all kinds of health certificates to prove I had no lung problems.

It seems like there is not much regulation, OR not much enforcement of existing regulations.... perhaps too much "cross my palms with pesos," and I will look the other way??

It is not just in your country, though, its the same in some other Asian countries, the muddy rivers, where a bit of gold can be washed with big dredges.

Dredges are illegal, here, you can go to jail, lose your possessions and be fined, if you can not pay the fine, you WILL go to jail. The fish are more important than people, here.

I just started on the forum after being away 2 days, so until I finish it, there is no news about detectors.... I need to set up a test breadboard and test out some of the stuff, I guess.

Do you have any friends or relatives, in Canada?? I do not know them, but I know there is a lot of PI people here. In Dawson Creek, BC, Fort St.John, BC and in Grande Prairie Alberta, there must be hundreds! It may be cool, here, but it seems to be popular, to your countrymen. I have a reason for asking and that is, if you have friends or relatives here, it would be safer than mail, if I were to send you anything.

One time I picked op a German immigrant lady, who had horses, she was feeding, near where I lived, and since she had no car, she was hitchhiking back to town.

She said, did I want to hear a German joke?

I said yeess, very cautiously, since I did not know what to expect.


She said:

"The Germans all own the land, the Americans have all the money, and the poor Canadians have to WORK for a living!" 

That is the way it is, here, no-one expects to be able to make a living, although some do, from treasure hunting..... remember that, if you ever HAVE to come to Canada, or the US.

Personally, I think there are some bad requirements, for immigrants, they want too much  from people.

I could go for a little more treasure hunting, though.
