Compass Depth Doubler

[ivconic]

A "luxury" model with mcu control, an automatic charger integrated into the device and a 12V / 12A battery is also being prepared,
as well as additional options for the operating time settings of the device, constant battery monitor, some alerts, some other parameters, all in the same box.
Work in progress...

Looking good.

I have already lost ~3 months on waiting various components to arrive from various locations.
Then I made few copies of the original unit.
Now I am waiting again for this (photos above) modified and mcu controled version.
This year 2023 I will remember very well as very "stupid" and financially bad year.
Keep waiting and waiting... and nothing depends on me.

Automatic charger, accu 12V / 7Ah, 20 probes, 2 cables with clips... finally finished!
I am so lazy last years... this should be being finished long time ago.

Sticker charge ground eliminator ака static charge ground eliminator and its benefits....

When the electricity is at rest and produces excess cation i.e. positive ions and negative ions that condition is termed as static discharge. Often the imbalance occurs due to changes in temperature, separation of ions or friction. This imbalance of ions can lead to several difficulties from minor electric problems to the risk of equipment damage or more. Static charge eliminator helps reduce these risks. Several industries such as automobile, electronics, medicines, printing, power generation and supply can be affected by static electricity.

Now that we know what’s static electricity, let’s look at how does static eliminator work towards stopping it.

How does a static eliminator work?

In order to combat the impact of static electricity, one can turn towards two main solutions such as:

• Active static control system
• Passive control system

While the active static control systems require power in order to function, the passive control systems simply absorb the static charge thus, reducing the effect. If compared the active static control solutions are more effective than the passive ones, because the former just simply eliminates the static electricity rather than reducing it. One of the most common active solutions is ionization (formation of ions). The process of ionizing neutralizes an unbalanced charge by eliminating any particle attraction that helps produce static electricity. Whereas passive control systems use grounding and electrostatic induction. Grounding uses direct electric connection via earthing, thus discharging any excess electrical charges. In the other technique of electrostatic induction, it produces the opposite charge of the unbalanced item and balances the effect.

Other methods of static elimination

Some other applications contain combining an air amplifier to a static eliminator bar- this neutralizes the inside of blow molded or injection molded containers, thus by loosening and removing plastic pieces accumulated during cutting processes. Blowing off plastic strings and pieces after a molding process is also another method. Particles tend to stick due to static charge; the static eliminator bar not only avoids the grounding effect of metal but also reduces the effectiveness of the ions generated.

Another way to work with a static eliminator bar is to push the ions with either low pressure compressed air or with blower air. Often manufacturers believe that air knives can push static charge particles at a considerable distance through compressed air. While it is true that compressed air operated air knife will succeed in pushing the ions, there are still chances that some recombination might occur due to turbulent flow. In simple terms, the further away the static eliminator bar is placed from a statically charged target, more time it will take to get rid of the static charge.

Static elimination techniques are many and manufacturers must determine if their products or machines are compromised by static electricity. The easiest way to identify this is by a static meter such as electrostatic field meter or voltmeter. Once the presence of static electricity is confirmed, manufacturers can fight or neutralize the problem with any of the techniques mentioned above.

We've mentioned this device briefly over the years. But very little information was not enough for us to gain insight.
From the first moment I heard about that device; I felt that there was something there.
And just when I had given up all hope that I would ever have the chance to see it in this lifetime... it just so happened that a good one turned up on Ebay.
Admittedly, the price was not small. It was obtained with much effort.
It came to my hands. And I did complete reverse engineering.
Now I have 100% correct pcb, 100% correct schematic and 100% correct all information.
I have already ordered 10 pcb from JLPcb, they have arrived and I have already done two devices.
I had to buy some components online from abroad.
I restored the original device to its original state. And did a series of tests with both original and DIY devices.
IT REALLY WORKS!
It's not a joke, it's not a hoax, it's not a marketing story; it really works, just as advertised way back when that production was around.
With the help of this device, any ordinary, solid detector; it gets much "deeper" and sees coins much deeper.
Tests have proven it. Both on dry and wet ground.
I've had a Deus 1 since 2012. I've gone through all my old favorite sites with it and picked up all those delicate finds left over.
And now the time has come that Deus no longer has anything to look for on those sites.
And on some of them I found a lot of antique silver coins, some gold coins and similar valuable finds.
Now with this device; with Depth Doubler: I get that same desire and enthusiasm to go back to old places and search everything again.
Because what I have seen in the tests so far; it gives me the right to believe that on those same sites I will find many more precious finds, which are deeper than the range of the detector.
I will give only one illustrative example.
I buried the Roman "denarius", silver, to a depth of 32 cm and tried it with Deus.
Deus can barely see it. Hardly any vague signal. But it still sees it.
Then I drop that coin to 40cm.
Deus doesn't see it a bit anymore, under any circumstances.
Then I put on the Depth Doubler and let it "work" for 40 minutes.
And then after that I try with Deus.
Deus now sees that coin loud and clear, unequivocally with a very strong response signal and a very stable VDI number.
As if the coin is at a depth of 10cm.
Then I further lowered the coin to a depth of 50cm. Deus still sees it, but with a very weak signal, often intermittent.
But when the coil is "crossed" left and right; the signal becomes much clearer.
A good enough signal to dig anyway.
No more dilemmas. The device works flawlessly. There is only one "problem" relatively speaking.
Deus 1 is a naturally "nervous" machine and constantly "flickers". When the settings are "hot".
That wiggle flicking is further amplified in the field where the Depth Doubler works.
It's annoying... but the signal on the coin is still very recognizable, it clearly stands out for its uniqueness and recognizability, and essentially that buzzing does not interfere with the precise location of the coin.
It is a small price to pay for the gain to be gained.
And then I brought a cheap Chinese MD4030 detector to that place for a joke.
And to my delight... it worked much deeper too! Not like Deus, the depths were smaller, but with the help of Depth Doubler they were almost twice as deep!!!
The good thing about the MD4030 is that it is a very quiet detector and it is much smaller flicking at it.
So with the addition of Depth Doubler, I have no reason even to think to get a new "almighty" metal detector, at least for the next couple of years, until I visit all the old sites with it and completely clean them of findings.
And now the most important thing. Much to the regret of many, I will not publish this project either on this forum or anywhere else.
Because I invested a lot of money and a lot of time to get to the device and do the complete reverse engineering.
Sincerely; it really cost me a lot.
A lot of money, a lot of nerves, a lot of work and too much time. And a lot of reverse engineering mistakes that I had to search for and correct later, in order to get to the final and 100% correct solution.
The matter is not at all naive, although it seems so at first glance.
A very original idea is used here in a very unusual and unconventional way.
It took me days and a series of measurements with an oscilloscope to figure out exactly which stage does what.
So I plan to make a dozen devices and sell them. With that money, I can somewhat compensate for all the expenses and effort.
So I will sell some and keep one for myself.
Such things are neither easily nor widely sold here in my small country.
So I have no intention of making more series.
I'm not even sure I'll build the 10 I have the pcb for.
I might just make a few pieces for a couple of friends.
So this whole project can be auctioned here on the forum, according to the principle of the highest bidder.
Logically, the one who pays a decent amount; I personally don't believe that he will later share the documentation for free on the forums, he's not that rich or stupid, is he?
You have my email and if you are interested in the project; send me an email with bids.
In case you don't have it; it is [email protected]
I will consider the first 5 best offers and decide. Let the bidding begin and let it run for the next 10 days.
My name, my seriousness in such matters, age and work on this forum; are enough guarantees that this is a very serious story.
I wouldn't risk my reputation on nonsense.
If all this didn't cost me so much, I would be in a big dilemma to publish everything as an open project.
But it cost so much that I have to return some of it back.
But once you try how this works; it won't occur to you to waste your money on some new metal detectors with ridiculous prices.

ivconic Keep silence like Partizan

Comic Font, like always.

It's just a habit.
I hope it does not offend you nor hurt your feelings?
I don't pay attention on such details.
Just a habit...

[ivconic]

Sometimes I honestly regret posting some things.
However, one should have understanding; a lot of money, time and effort was invested in some works.
It is normal to expect at least some of it to return.
Depth doubler is one such work. It all cost me too much.
You can't expect me to share all that for nothing now.
As for private messages, I just have no idea how to respond to some messages.
It's always fairer to discuss things publicly on a forum.
Everything else I simply will not comment on.
I have had enough mistakes on this forum in the past.

Inconic good evening. Have you tried using your miracle in tandem with Equinox 900?

Inconic good evening. Have you tried using your miracle in tandem with Equinox 900?

My miracle?
Not my miracle and not "miracle" at all.
It is just pretty straightforward device made by Compass long time ago.
In my language such question will be understood as mockery and offend.
Answer: no, I never had chance to see any Equinox nor to test it.
Those are rare models here.
XP is the mostly desired brand here.
