Can anyone direct me to any patent or patents for the Axiom?
Thanking you

I've seen nothing so far. -
Thank you Carl.But Garret are claiming in some publicity that the axiom pulse technology is patented?Comment

I don't know, I haven't seen any patent claims from them so far. It's possible they have a patent in the works that hasn't gotten far enough to be published even as an application. It's likely they will patent the mechanical system, I would expect at least a design patent and maybe a utility patent, both of which they did for the ProPointer.Comment

There may be patents .... but looking at the hi res photos of the AXIOM pcb in the FCC report ... It looks pretty ornery inside to me. No white paint at least.
I also noted a liberal sprinkling of what seems like trimpots across the board. I am sorry mr Garret but I will not pay AUD8000+ dollars for a device in the 21st century with trimpots on it. ??? ( vibration and drift issues )
You can see the FCC report here https://fcc.report/FCC-ID/DBDZLYNK23533X/6263691
Also the way the coil cord comes out the back of display housing could be better. Sorry.

Yup. Looks like lots of static rings and trimpots. Some sort of SAH-s? Guess it is not a direct sampling Rx.
BT (or something) is a part of the board.Comment

I dunno, overall it looks pretty solid to me. I doubt those stages withe trimpots are demods, I see no demod caps, at least the kinds I would expect to see. I would expect direct sampling. Most likely that 64-pin chip below the micro is the ADC; knowing what that is will tell you if it's analog demods or direct sampling.
The coil connector is very solid, it's an SMT connector that eliminates fly wires. FTP uses them extensively with no problems.
I'm a little surprised that the FET switch is an IRF640. That's pretty unaggressive IMO.Comment

as soon as I saw the first videos I immediately thought of this detector I will buy it !!as soon as I saw prices.. I lowered the ears.Comment

2 fast switching diodes U3G ( ONsemiconductors ) , a capacitor that stores the flyback energy , IRF640S , MJE15031G ( PNP bipolar tran. ) – these elements are on a circuit board on GARRETT ATX . Probably TX oscillograms are the same or similar .Pulse train -240 us (linear increase in current through TX coil ) ,840 us pause , 20 us short pulse (almost constant current formed with with kick start ) and 260us pause . Improved signal processing, new software- new detector…

I see that Garrett was just issued a patent on the Axiom, but it is a design patent:

I still see nothing on the tech side.Comment

It's a design patent, on the look-and-feel of the mechanical design. It is a very useful way to sue counterfeiters or anyone who makes a look-a-like product, like those Chinese detectors that look just like a T2 or Goldbug. However, Garrett also got a design patent on the ProPointer and the market is now flooded with copycat products, and Garrett did nothing about it. So I do question their commitment. OTOH, it's tough to deal with the Chinese copycats, turns into a game of whack-a-mole.

And again, on the other hand; that design is very reminiscent of a dozen new models from various manufacturers that we have seen recently.
Starting with the ML models, through Nokta/Makro, to Quest... etc
In all cases, I strongly criticized such a enclosure and the position and height of the cable coil connector.
And it has already become a "professional deformation" for me to immediately notice such things.
Speaking of Chinese copies... Gold Bug Pro copies are not only "look and feel" but direct 100% copies of the originals.
I had a couple of pieces on tests and was convinced.
As far as copying is concerned; I am not declaratively in favor of it and I do not support such activities, if the goal is to
turn it into mass production and earn money at the expense of other people's knowledge and effort.
I partially support copying, i.e. "reverse engineering", only and only for the purpose of education, learning new things and expanding personal perspectives.
Because on the other hand, we had decades of impenetrable "wall of secrets and silence" by those who knew more than us.
If knowledge is hidden for the purpose of acquiring and accumulating capital... then that knowledge has no special value for humanity.
But that's another story, those are the differences in the outlook on life and the organization of society. It would not be a topic for here at the moment.
I wanted to start something else on the forum, very interesting, but I see no reason why I should not mention it here.
If you have a pcb with components designed and built by someone else. And you don't have a schematic.
Is it possible to "extract" the schematic from the pcb in an easy way?
The emphasis is on the "easy way".
Because a much "harder way" already exists in practice and I have been practicing it forever.
It is manually "on foot" copying the connections and components from the pcb using a simple visual method.
It is possible and gives good results as long as it deals with simpler and medium complex designs.
But with very complex designs it becomes a very difficult job, sometimes impossible.
Is there a piece of software that does this? The answer is no.
Unless it is part of the same package that generates multiple helper files with all existing data. But outside of that, no.
Not that we, the public, know.
So how do the Chinese manage to make 100% identical copies like that? I assume they have such software. That they developed it in the meantime.
It is software that would be of interest to several tens or even hundreds of millions of people in the world, in my humble opinion.
Software that must rely on some form of highly specialized AI. You input it a blueprint of the pcb and it draws the exact schematic from it.
A one-day experimental search of the Internet showed me that such software does not exist publicly and that no one knows that such a thing exists.
So I arranged a business meeting with my younger son, where I proposed that this be our next project.
That in the period ahead we start working on writing such software.

He has already switched to the 11th generation Intel processor, with the addition of a very powerful graphics card,
while I have stopped at the 10th generation still. In January, I plan to add a powerful graphics card as well.
So we have enough resources. All that remains is to compile the correct algorithm on paper and start writing the code.
I also mentioned graphics cards because nowadays it is possible to combine their performance with the CPU's push for tasks that are not strictly graphic.
First of all, I have in mind the use of the arithmetic/mathematical unit, which in those cards is much more powerful than the system one.
Because for that task we first need to write a specialized AI.
Why and what are the motives for all this?
Challenge? In a way yes, maybe.
But above all, I am someone who is used to making his own tools for further work.
And there is also the financial moment. Such software will not be offered as a complete package, but only as an online service.
You register, upload gerber, cpl and bom files and the online service generates a schematic for you.
In order to download, you must first pay a certain amount to the account.
This also entails creating a huge database of components with their detailed descriptions.
It's a trivial job, so I decided not to do it, but to use one of the existing databases.
I'm interested in the general opinion on this idea?Comment

I've used some VHDL tools that can automatically generate a schematic diagram, but the results are (being kind) "less than satisfactory".
It will be interesting to see if you have any success creating a decent schematic from a PCB layout. This looks like an extremely difficult task.
