I recently stumbled upon this website: https://www.goldaks.com/ (https://www.goldaks.com/)
They are claiming to sell a gold detector that works over a hilarious distance, quote: "based on ion technology emitted from magnetic fields buried in the ground".
"A valuable and important part of our product is of course the mother board, which is encrypted in this panel and the formula for our unique algorithm developed over decades. This algorithm is the secret of our success."
"Laser Distance Sensor (LDS) Intelligent scanning for high efficiency. Allows the device to scan its surroungings at 360 degrees, 3600 times per second"
The chinese knockoffs can even detect diamonds. :scared:
etc.... :-DD
Retail price starts at $2.700,-
google for "aks detector" There are a lot of websites out there, selling this POS.
What do you think?
-
This is a tricky one. They have a device which can detect gold worth millions and millions of dollars, and they have a need to sell the device to other people. What do you think, true or scam? ;)

Perhaps they're agoraphobic and can't go out to find the millions and millions of dollars for themselves?
Maybe they're philanthropists?
-
Would they send the device to a customer, and the customer will pay the device with the gold they find? No royalties for the gold found? They aren't too clever marketing people after all, so they have to be philanthropists.

"GOLD AKS, which are classified and located in the United States in Texas and Israel in Silicon Valley"
So why does the voiceover sound like Chinglish, or at least certainly not scripted by a native English speaker.

The adress in Austin is not a plant, its just an office building. The same is true for the Tel Aviv adress.
Besides that, I am not aware of any known physical mechanism that would allow to detect different material, including non conductive stuff like diamonds burried 70m deep and 5km away from the detector, using earths magnetig field, ions and antennas.

I bet they're just reselling the same Chinese crap they're accusing of being fake.

Which incidentally is well inside my "buy for teardown" limit. Stay tuned.... :D

Just for a laugh and out of curiosity silly me went looking for Youtube videos in regards to "long range detection" and in particular the comments sections, I really wish I hadn't now, I discovered there are those who actually believe in this garbage and are using gadgets such as these as a type of beeping dowsing device.
Disturbing stuff I must say. :o ::)
-

No this is only true veritable device. Here happy customer for you knowledge
Finally i found this unique device i searched over 4 years about this product and i bought 3 different fakes of this aks device they are all fakes and dont work at all.. i wanted to believe in this fakes devices but when you will buy this GOLD AKS original you will understand why you will all the time be in the field and search and find treasures as easy i just thank god because i have this device thank you AHMAD

I wonder why these guys don't use the AKS Gold Detector:
"Yukon Gold"
https://www.imdb.com/title/tt2758692/ (https://www.imdb.com/title/tt2758692/)
They would get much more money using AKS Gold Detector compared to the money they get from the reality show. ;)
Ps. Why Ahmad is only a Silver Member, although he has bought AKS Gold Detector?

So why does the voiceover sound like Chinglish, or at least certainly not scripted by a native English speaker.
The citations from 'satisfied customers' read in a startlingly similar way to the rest of the site, hmmmm, could it be that they were written by the same people?
-
To be honest, I'm considering buying one. I've emailed them about a very-short-range version as I'm subject to electromagnetic hypersensitivity.

Talking about testimonials, this is my favorite:
I have bought more than 300,000 devices in my life all my life. I am trying to find the device that will take me to the exact point and blessed prophet Muhammad who brought me to the exact point. Thank you for the advanced and real advanced technology Ali Saudi Arabia

You can detect gold from a distance, using spectrometry and an excitation source, say a laser.. but if you have something that can bore through 5km of rock or soil, you can just sell that as a weapon.
That said, an affordable portable laser spectrometer for prospecting purposes would be wonderful. Detecting just elemental metals like gold, silver, platinum, and palladium would suffice.
-
Looks like an upgraded version of the ADE 651 (https://en.wikipedia.org/wiki/ADE_651) with multiple WiFi antennas instead of a single FM radio antenna! The ADE 651 was a far bigger + dodgier scam though with the kickbacks and bribes that meant some places actually used it for bomb detection |O
-

I what you described already exists and it is sold by Olympus (the ones doing cameras and microscopes) it uses X-ray fluorescence spectroscopy and tells you the elemental make up of almost anything, they are less useful/precise with light elements but for heavier stuff like silver and gold they are perfect
They are battery powered and remind a heat gun in shape and size

Exactly. Metal detecting is rubbish, spectroscopy is where it's at. There are plenty of handheld spectrometers on the market.
There are also bore-hole laser spectrometers. However, they are terrible ugly machines that look like a ton of air conditioners strapped to a back-hoe.
I personally had the idea of a small and portable fluoroscope device (using similar but a bit stronger emitters/detectors than the handhelds) that could simply be attached to the end of a cable and lowered down the hole and sample the walls on the way down. You could choose between wired or battery operated wireless versions.
-
Here is a picture of some rocks from a very rich gold vein deep inside a hard rock mine; note the tiny little chunks of gold that I have circled. With real detecting equipment these possibly could be detected at 5 Centimeters. The fancy x-ray device that Cody's Lab has might be able to give a reasonable assay.
History has proven that the suppliers to fools rushing for gold have a much better business plan than the gold seekers.
-

Those are bigger than the nuggets I've ever panned! ;D Well, maybe not, but definitely in the same approx. 1-2mm diameter range.
That said, I was thinking of a contact meter that could detect trace amounts (of a few precious metals) from a freshly chipped stone face, not a tool for locating mineable veins or actual nuggets...
(The "mother lode" part was supposed to be a joke. There are interesting formations in Northern Finland, including completely eroded old volcanoes, with just the "magma pipe" (not a geologist, don't know the correct term) parts left, and the bedrock on the surface; not much soil. It'd be interesting to just go for a trek, chip some stones, and see what lies under the surface, mapping some out.)

I saw one of those once when I hauled in a load of scrap material from my friend's machine shop. There were a few good sized chunks machined out of billet alloy and the guy at the scrapyard had a handheld device that showed the precise makeup of the alloy. Seemed practically magic, at the time I'd never seen anything like it.
-
The usefulness of these devices for alloy identification really depends on the base material, the biggest problem for them is steel. where this systems can give you only a rough idea of which type of steel you are looking at, this is because the most important alloying element in steel is carbon and it is almost impossible to get a correct reading for it due to surface contamination which is difficult to eliminate in a vacuum (in SEM systems with XRF capability)and basically impossible in the field

The golden color of gold is not very specific. So one can not really distinguish gold from other materials that look like it by optical spectroscopy.
Xray florescent spectroscopy works, but is an rather expensive instrument and may need a special permit because of the radiation involved.
-
Wait, they are not talking about detecting gold that is exposed. They are talking about detecting gold that is burried 70m and 5km away, like captain Jack Sparrow's compass pointing to what he wanted most .
Spectroscopy won't work that way. So no, there is no such technology that could do, what these people claim.

Flouroscopy can go several inches, but the power required to go even over a foot would require some sort of massive X-ray laser or something. Maybe one day when we go mining asteroids or something we'll have spectrometers strong enough to go that far, but that would still be impractical (and dangerous) on Earth.

Makes sense. In this case it was aluminum, prices on steel scrap were so low at the time they'd usually just give it to one of the roving scrappers who would stop by occasionally rather than pay somebody to haul a load to cash it in.

It's arrived... just in time for the Lunar Eclipse :scared:

Huh, that's top notch, it only detects the very best of things, even "diam"onds!?!?! (what's the "diam" setting for?) None of that rusty ferrous rubbish.
-
Well this solves the mystery of the second box.
It's just a 315MHz remote keyfob, with a huge nicad or NiMH pac, the sole purpose of which is to keep the green "on" light lit.
Pressing the buttons lights the corresponding LED on the back of the main unit. Meanwhile a "scanner" LED on the main unit cycles an RGB fade sequence that looks a lot like those LEDs with built-in effects...
Surprisingly it does work from inside the aluminium extruded case.
Main unit feels like it might be potted.

A generous antenna.

They sound like the folks I did a job for many years ago ... (usual rich arabs) ... they asked if I could make them a metal detector that could work to a depth
of 10Mtrs or so ... and and .. detect other precious metals ... and and ... display the approximate worth (so they wouldn't bother digging it up if it wasn't worth it) ..
Just for fun I suggested that it could be operated from a low flying helicopter - you can cover MUCH more ground faster !!
That got them excited !! "You make us one and we'll pay you $10,000 CASH ... no wait $20,000 CASH .... ok after we make enough to cover costs of course"
Yup, they're out there and STILL breeding !!

Damn, i am late with my prediction you will find a LED and a capacitor/resistor inside.

X-ray shows what looks like a small ferrite rod antenna at the end of the plastic nose. Scope shows 60Khz signal.
It beeps if you take the end within an inch or so of a large metal object. Metal type setting makes no difference.
By bet is it's the same as a cheap DIY buried pipe detector, so their description as being a metal detector is actually true...

LOL, lazy idiots probably couldn't figure out a value from a percent/concentration number anyway. Doing that automatically would require an internet connection to a server and everything else (to track market prices).

From the aliexpress link:
Due to the presence of magnetic storms and solar aurora, the instrument must be commissioned for a period of time before it can be used normally. The receiver will continue to receive signals during this time, but the instrument will not respond. This situation is beyond the control of the Ravens. It takes time to adapt.
Expect some tapping and rapping on your workshop door Mike, that'll be the support tech fluttering in to set the device up for its operational mode ;) No wonder your initial results during the solar eclipse were underwhelming.

Looks like this device is basically intended to be sold by hustlers to gullible marks, it's all set up to give an impressive demonstration by having an assistant pressing the remote buttons at the right times.

It's surprising there's active electronics in there... I was expecting something more like the fake bomb detectors: https://en.wikipedia.org/wiki/Quadro_Tracker

There are plenty of metal detectors that can distinguish metal types, they couldn't even be bothered to make it actually do that.

There are some gold miners who are using “wireless detection” and fly over to spot possible gold deposits. But it got something to do with what else is present around gold usually - that emits some ?Ions? which are detectable from the air.
So it does not detect the gold - and would not find a dropped gold coin. But apparently they can find the ore with it.
Last I heard about it was on Frank Curzio interview with one of the miners - 2-3 weeks ago. I think this is the podcast: https://www.curzioresearch.com/the-incredible-story-of-a-not-so-typical-gold-miner/ (https://www.curzioresearch.com/the-incredible-story-of-a-not-so-typical-gold-miner/)
If it works or not I do not know :) but Frank Curzio is (apart from sounding like a US boiler room trader) - quite often right on his market predictions.

Sounds very much like dowsing. Substitute "ions" for whatever BS excuse of the day, it works equally well.
Now there are some remote sensing techniques using even satellite imaging - but those work by detecting geological changes/discontinuities using hyperspectral images to map out promising areas for further exploration.
e.g.: https://www.researchgate.net/publication/222300125_Detecting_areas_of_high-potential_gold_mineralization_using_ASTER_data (https://www.researchgate.net/publication/222300125_Detecting_areas_of_high-potential_gold_mineralization_using_ASTER_data)

Would it be possible to have a long range spectrometer? Sort of like Star Trek sensors. I mean, the power output might be quite dangerous, so you'd have to clear the area before scanning.

Did some experiments with metal detecting many years ago, and found that the two coil T/R induction type is best for general use. It's relatively easy to discriminate between iron and nonferrous metals, but discriminating between nonferrous metals is hard as there is essentially no difference in the magnetic effects of aluminium or precious metals. Gold or silver gives a stronger signal per mass because of its better conductivity, but then a drinks can is larger than a ring or coin so that cancels out. Interestingly I did find that cupronickel allow such as some UK coins are made of could be identified by its magnetic reluctance, albeit only at close range.
I can't imagine a ferrite rod would be any use except for very short range, the larger the diameter of air-cored coil you can manage, the better the depth penetration.

The main PCB appears to be from a cheap MD300 handheld metal detector.

Even better!
The last paragraph of that page is a gold nugget :bullshit::
If no obvious target is found when you reach 200 feet, then the target was most likely subatomic gold particles - you cannot see it and most chemical analyses will not detect it either, but the MFD will.
I'm pretty confident that with its help one will be able to dig out protons, neutron and electrons in various combinations.
