Long range gold detection (yes prospecting) with a handheld antenna!

What?  There seem to be a lot of these listings.


I wonder how it even determines when to light a detection light or if there's anything in that aluminum tube... definitely could just leave the SMAs for standard bargain basement 2.4GHz wifi antennas unconnected on the inside, but maybe they at least have wires to them to look like they're doing something if someone takes it apart.

These scams have been around a long time (probably since portable metal detectors came on the market).

There's another one here. https://www.eevblog.com/forum/dodgy-technology/long-range-gold-detector-bionic-x4/

I know of numerous small scale miners in zimbabwe who hired the Real true gold detector AKS from a chap in harare.All of these miners  succesfully mapped and encountered reef  between 21m-25m as identified by this detector.It certainly worked.

#Not a Scam.

Lol. 

You know the old saying about the Klondike goldrush? It was not the prospectors that got rich, but those selling the shovels

Claiming "not a scam" usually means "scam".
It would be indeed possible to find areas of *possible* locations (old riverbeds with deposits of Magnetite, which sometimes also contain gold deposits), there is no way to know in advance, as you can only detect the Magnetite. Depending on the local geology it might be a good clue though, or it does not mean anything. So it's the knowledge of the surveyor which matters.
However there is no technological means to detect gold somewhat deeper below (it will work only reliably for a few dozens of centimeters), so this "long range detecter" is not able to detect gold deposits. Point.

probably it's based on startrek's long range sensors

probably it's based on startrek's long range sensors   

I mean, there are satellites that can scan for ore deposits (with a certain confidence). There are ways to scan for ores using spectrometers and whatnot. There are even retrofitted diggers with mass spectrometors on them to scan the ground (looks like a bunch of AC units strapped on, like something from BTTF). Hell, in geology class I drew an envisioning of a high power X-ray spectrometer that could be dropped down a bore hole to replace those wacky diesel spectrometers (Something I might actually persue as a patent/product in the future, big what if though).

But a simple electromagnetic handheld metal detector that you can just wave around with no dangerous radiation or lasers? Hell no. That's not how spectroscopy works. That's not even how metal detectors work, too small a signal to pick up some gold flakes in the dirt.

And we're supposed to just take your word for it? Well, you must think your word is worth a lot indeed, since you created an account just so you could post that... on a topic almost two years old, not any less

Maybe the guy who made those fake mine detectors has just got out of jail ...?

some reference to those satellites ? i would like to know how they scan , apart from indirect clues coming from imaging done in various wavelengths (and that's far far away from any kind of spectroscopy or any other means to identify elements).

EDIT: it's not traditional spectroscopy, it's more of detecting mineral traces through either certain wavelengths or special lidar.

exactly, that's why i mentioned

apart from indirect clues coming from imaging done in various wavelengths (and that's far far away from any kind of spectroscopy or any other means to identify elements).

those satellites are doing exactly that... imaging in various wavelengths (radio , infra, visible...) and some smart dudes were correlating the data with known locations of various ores and developing methods to identify possible new locations based on the imaging data... but it has nothing to do with identifying various elements. the opening post was "long range gold detection" and there is simply no such thing, hence my joke referring to startrek.
