Compass Depth Doubler

[ivconic]

I would be interested to know if this device works successfully with more than one detector operating within the ring of electrodes. Something for you to try when it stops raining.

Honestly; I haven't tried more then one at the time.
Deus and one "Made in China".
Both showed improved depths and indeed those were real improvements.
What's interesting is that one "Made in China" and with price ~100e at local market, ~40e at Aliexpress.
It becomes really usable and serious detector with Depth Doubler running.
What's even better; it performs calmer than Deus. Not too much chattering.
Of course, it can not beat the Deus in depths. But it was interesting to se how nice it was performing.
As for your question; I don't see a reason why it should not be few detectors to work at the same time on covered area.
Maybe if they work on close frequencies will be interferences, probably yes.
But that has nothing to to with presence of the Depth Doubler.
Or maybe it will have, maybe DD will emphasize the inteferences even more?
I can't tell.

Let me know when you have worked out your price. I think it would be an interesting experiment to locate possible deep targets.

It would help if Ivconic did give some indication of the price he's wanting. That would avoid the problem of low-ball offers.

I described an alternative probe layout earlier, but thought a picture would explain it better ( attached ).
Only 14 probes are needed to cover 6m x 5m , the same area as two rows of 10 probes 3m apart. If the electronics box was built with two yellow and two blue sockets, this three-row arrangement would be neater to wire up.
Electrically, this presents the same ground resistance to the box as two rows of 10.

The concept of the auction is that you bid yourself. Ok, there are auctions where the starting price is given and the participants raise...
My goal is not to "earn" the money. My goal is just to return the investment so far.
And now I should say how much is it? The problem is that I don't know myself. Somewhere in the meantime I lost count.
I had additional expenses when purchasing some parts, which are not available on the local market. I had to order from abroad.
There are extra costs for postage and waiting for a month each (from Aliexpress).
Everything could be found on Amazon and Ebay. But it is cheapest for me to buy through Aliexpress.
For someone living in the EU, UK and USA; parts will be much cheaper and easier to obtain from multiple sources.
For such, the production of the device will cost no more than 50e/$ in the end!
But for me the costs ended up being many times that!
There are 3 components, which I had to order that way.
With one, there was a big dilemma whether the Chinese copy would work at all, but luckily when it arrived and when I put it on the pcb,
measured everything with an oscilloscope, it works just like the original.
Long story short, I wasted about 2 months just on such trivia.
All this should not interest you.
I don't know what to say.
I thought that those who participate in the auction form the price themselves based on how they value such a device in their head.
And there is another important factor!
Once someone "buys" a project, he can decide to make it public, or share it with multiple people via email, or whatever.
Sooner or later it will appear on some forum. At that moment, I can no longer sell a single finished device here in my area.
Because Serbia is a very small country and there are too many people who follow forums, make devices and immediately offer them on local ads.
Worst of all, they create competition, kill the prices and in the end the whole story becomes meaningless.
Because the device is completely analog, there is no processor, there are no special chips, with which the device would be protected from copying.
Anyone can make it easily.
Why am I saying all this? Because once the project leaves me; it's over, I can freely forget about further work on it.
That is why it is necessary to "sell" well.
I have not yet started selling ready-made devices here in my area.
I am waiting for the components for a dozen devices to arrive.
I don't believe I will make and sell a dozen... but those components are interesting for other works.
I only had money a few months ago for components for one device, say for proof of concept.
So I'm terribly late with all of this. There is no money. There is a lot of waiting.
That is why it is best that the auction be "incognito" via email.
I will not publish who bid and how much.
I'll just pick the one with the highest bid and email everything to him after payment.
I can only inform the participants at the end how much it was sold for.
Unfortunately, the deadline I set in the beginning has passed, and the few bids I received by email are below the minimum, more like a joke.
So I don't know what to do next.

That's interesting!

That's interesting!

Yes, but it reduces the detectable area.

[Skippy]

In what way ? You're thinking about the area covered by the probes? About the same by my calculation. It depends on how much 'spread' around the probes there is. 10 probes 3m apart strictly covers 9 x 3 = 27 m² , but in practice may spread 0.5m beyond the ends of the rectangle, giving ( 9 + 0.5 + 0.5 )m x 3m = 30 m². Whereas the three-row arrangement covers (4 x 1.2 )m x 3m x 2 = 4.8 x 6 = 28.8m², if you allow some 0.5m spread beyond the ends of the 4-probe line. Which is much the same as the two-row's area. You could always use 5 probes in the middle row and position them directly lined up with the outer rows. Space them 1.25m apart if you like.
If you're concerned about detecting near the probes, and getting a signal from them ... I am concerned about that, too. The three-row arrangement 'looks' like 18 probes, hardly any different or better than the two-row.
What you could do with the three-row arrangement that's different, is:
After running the device for 30 minutes 'charge up' , switch off, quickly remove the middle row, connect the blue and yellow to the remaining outer rows, and re-apply the power. That may help retain the 'charge' , while giving you a 6m wide area to detect with no big metal pegs inthe middle.

Speaking of which ... steel probes will ID as 'iron' to a detector ( I hope ), but aluminium probes will surely give what the Yanks would call a 'Quarter signal' . This may or may not be a nuisance.

decide what you want to make of the device.
add to it a bit $$ more and then some more $$ and double it.
pick the 3 highest biters and average the $$
divide the total by the people that show interest and bit for it.
hopefully the number of people by the price average will cover your costs.
inform all bitters the selling price and is going to be more than one buyer.
if they all agree collect the money and release the info.
it may work
then again what do i know

I don't know if I understood correctly, but you gave me an idea!
Let's see here how many people are interested and divide my "desired" sum into so many and that each interested person pays that part of the sum!
When all those interested send money (pay pal for example), at the same moment I send them emails with documentation.
It is a good method, provided that all concerned are immediately ready to react.
It's a bad method if it's all done publicly.
I suggest that everyone who is interested declare by email , and that we talk secretly about the money.
The rest of the visitors to the topic do not need to know the details.
The good thing about this method is that the more people sign up to be interested; the part they have to pay will be smaller.
My free estimate is that for now there are 2-3 interested.
That's not good.
It is not fair to the majority involved, because one of them might have share the documentation with the others "not interesed".
But we are looking for a good solution for everyone interested.
I know from experience that things like this are best done when they are out of the public eye.
Anyone who is interested and wants to pay a part; should not be exposed to the public.
Because then the others will "bury" him with emails in the style: "Master...bro please send me..."
It is best if those interested "apply" to me either by email or by private message.
And in my opinion, the best method is Viber.
Enter my phone number in the contact list and Viber will overtake it.
Then we can correspond p2p.
I don't like to use the camera, I mostly use Viber for texting.
Number is: +381 65 830 4004
I will not answer calls outside of Viber.
With Viber, it's good that more of us can be in a conference chat. A kind of private "topic".
Take some sum as an example and mathematically explain to me exactly what you wrote, I didn't fully understand.
There is one problem with Viber, the time difference... when I'm online and someone else, maybe someone else won't be able to,
because it's night at his place and he's resting.
The good thing is that Viber keeps messages so you can reply to them later.
I used to use Skype, but Viber is much more direct and the important thing is that it is linked to a phone number.
And of course, email is perhaps the most affordable solution for everyone.

In case of running Depth Doubler; smaller diammeter coil will do. Targets are much more "bigger" under the influence of Depth Doubler, so smaller coils would see such targets.
Let me remind; Depth Doubler is also made for nugget hunting (I posted PDF about that earlier).
Smaller coils will be more suitable to search the area and yet not to be bothered by the probes.
Duraluminum I picked is of very weak magnetic properties.
One lose less search area with such probes.

sorry but at this time i can't use Viber.
i try to send a pm but its not going through

Post # 128 Hi Skippy, thanks for your explanation.

[ivconic]

Why did I give my phone so lightly?
This belongs to a completely different topic, unfortunately there is no Off topic part of the forum,
and I see that the activity on the forum has died down and there are barely ten of us who are still there.
I freely leave my personal information on the Internet everywhere, not just here.
Because I have nothing to hide and I am not afraid of any misuse of that data.
But that is not my main motive.
My main motive is the great revolt that I feel, which grows more and more every day, against the great hysteria that has developed in recent years, on these topics.
We are witnessing that in today's world everything is exaggerated!
But for the evil to be greater; in everything that is totally trivial and irrelevant.
It's about the agenda.
People are trained and their brains are filled with various paranoia.
So, a completely irrelevant character somewhere in some nebulous place, who doesn't even have underwear on his aS$, is most afraid for his "personal data"!!!

People give themselves too much importance.
It should be understood that each of us is just a grain of sand in a desert like the Sahara.
One phenomenon is interesting; the less valuable a person is: the more they fear for their privacy.
I see this every day.
As soon as I turn on my computer in the morning, go to this or that social network, watch some news,
browse YouTube content... it's simply impossible to avoid such occurrences! What has the world turned into?
Internet resources are more and more occupied with such idiotic trivial, worthless and extremely irrelevant stories!
The right to privacy is violently abused by the proponents of that agenda, so apples and pears are mixed,
the exchange of theses and great demagogy on all sides!
Watching all this idiocy grow year after year; A great revolt against it accumulates in me.
I love to watch short videos, for example, either on YouTube or on social networks,
when a normal person with normal questions and one of those small-minded proponents of those ideologies "collide".
Piers Morgan is my favorite character! He "*ucks" their brains with very simple and normal questions.
Jordan Peterson also has regular encounters with such figures, I also love to watch him.
Or a series of idiotic videos, mostly in the USA, when some fat and incredibly ugly and disgusting woman makes a terrible scene about someone accidentally holding a phone with the camera on around her.
And similar situations.
All this is like a bad dream, from which I can never wake up!
And that's why I had a big revolt.
That's why I don't hide my data, I think I'm just as (un)important as everyone else on the planet.
I don't even have criminal dreams, much less thoughts, and the least intentions.
I have no guilty conscience.
I don't have any particularly bad deeds in the past.
I am not perverted by any criteria.
And that's why I'm free as a bird in the sky.
And I'm sure the vast majority of humanity is the same.
I paid for all my mistakes, I didn't owe anything.
And every further mistake I make; it hits my head equally.
And there is nothing to hide there.
So I felt the need to write this.
Am I the only one who notices these things?
Or do any of you notice that there is something seriously wrong with the world today?
First of all, I mean on a micro level, in the minds of ordinary people.
