Metal detector experiments.

Very Good working prototype. When you can see the scheme of the device?

[M.D. prototypes]

Bricks and pottery are only mildly mineralized, true mineralized ground is highly mineralized and highly magnetic. Picture below is of a small sample of highly mineralized ground I use to test my PI circuits.

I think you're right if you compare the highly mineralized ground in Australia with potsherds, stones etcetera from The Netherlands or maybe in Europe.
Anyway, if the Garrett pinpointer detected in such a way(like the pottery fragments as shown in the video),
That is mine "Dutch standard" for highly mineralized bricks, pottery etcetera.

The experiment with the potsherds and stone in the video is more difficult for a VLF detector, than the experiments that we've done in our bin (1.2 x 1.2 x 0.7 meters) full of mineralized and magnetic hydro grain "mine highly mineralized Dutch standard" that we use for experiments. (See picture below.)
This is because of the difference in:First, the height between the stone and the pottery fragments
Second, the difference in mineralization between the stone
and the pottery fragments and;
Third, by the irregularities in the pottery fragments themselves.

I must confess that I am jealous of your bin with Australians ground.

I suppose if your designing a detector to sell in your region, then your methods for testing ground balance will be fine.

In your picture in post 32, you could try crushing some of it, to make the sample irregular then see how the detector copes.

That's a good idea to crushed some hydro grain.

I'm definitely going do it and experimenting with it to see how the detector behaves and make a video of it.

if i could buy a detector from central europe which is made for our Environment i would be happy

Hello smity,

We have kept working on the project during the last period. Recently, we have made several test boxes. You can see them in the video below.

If someone has any tips or ideas, than we would like to hear them.

Thanks for watching!

Kind regards

M.D. prototypes, in the first test your appliance worked perfectly! Reveal more circuit!

M.D. prototypes, why do not you show circuit?
And this is our answer. MD. "Mole 2". All information on the self-assembly of the device is in the public domain, for free!

Your detector is impressive. I've never seen a VLF detector like yours. I would like to buy one. How much would it cost? Congratulations on your product. A greeting.
Eduardo.

Thank you for your positive comments.
It is not the intention of our experiments to use or abuse it for commercial purposes.
We want to share it with you , and see what the possibilities of a VLF are.
If you have interest, please conact us via a personal message.

Saludos cordiales,
Regards
