  • Compass Depth Doubler

    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.

      Now that I've written all this... I'm sitting and thinking... I missed a brilliantly "dishonest and sneaky" idea!
      Who makes metal detectors for sale... and there are a lot of them here on the forum, they are constantly filming for Youtube various demonstrations of how well their detectors work.
      And how their detectors are often "superior" compared to some good models from reputable companies.
      Hmmm... with Depth Doubler included in the "equation" ... 2+2=?
      I'll stop here. I don't want to start an avalanche...

          That's the point.
          I can't publish easy visible ones because it is "commercial" for me.

                What are we bidding on here? One populated PCB ? And we need to provide a suitable case for it. And it needs a set of 20 earth probes, 10 to each output terminal. And a decent size 12 Volt battery system to power it all?

                  Can you point to a link for the user's manual?
                  will be an interesting read for the one that never hear about it before

                        Yes.
                        At bench experiments with 15 ohms / 20W it draws 0.78A. In soil it is variable, depending on soil.
                        12V/5A or 12V/7A gell cell will do. My APC UPS is using two x 7A.
                        So it is common accus.
                        20 probes, also less then that will do, depends on the desired area and target size of interest.

                          I too have been looking for more detailed information for years.
                          I did not find.
                          This is an old product.
                          But the instruction would be very simple.
                          It has two LEDs.
                          The red diode is used to show the state of the battery... BUT also a very useful indicator when placing probes in the soil.
                          If the device draws too much current; the voltage on the battery will drop a little, the red LED will start flashing.
                          And when the battery runs out, it's time to top it up; the red LED will light up constantly. The device will stop working.
                          This is solved in a very interesting way.
                          I'm tempted to explain what I discovered with those solutions... but that would spoil my idea of ​​"secret".
                          The green LED indicates that the device is working. It can light up constantly or it can blink, depending on how the signal penetrates the soil.
                          It has two cables with 10 probes each. Separate the cables at a certain distance and push the probe into the soil.
                          Turn on the device to work.
                          The first effects are already after 30 minutes of work.
                          Depending on the conductivity of the soil.
                          Sometimes 30 minutes and sometimes 2 hours are enough to achieve the full effect.
                          When that time has passed, the soil can be searched with the detector.
