I just decided to buy that precious metal verifier. Thanks for sharing the experiences and taking the risk to try it among the first. Already contacted the company, next week they will provide me with euro side payment info that saves me from paypal/dollars etc. It's a price tag that is very reasonable for small fish like me.
The bar is "not quite" in the middle. How OK is that? To me it seems like the "apparatus" is not so sure whether it's genuine, but it's "pretty sure".
http://www.sigmametalytics.com/information.html says that if fake it shows an arrow on the bar display.
Mucking around with mine I found that it also works on the 5, 10 Oz and 1 Kg S2 Lunars without using a wand Lunar Rolls (20 x 1Oz), and 20 x 1 Oz Tubes ASE, Generic etc. I must say that the Sigma works better then I expected it to

On purpose fakes sellers (it's for a reason that auctions on sites like alibaba show quantities of 1000's to order) will certainly not like this precious metal verifier, as it's a rather cheap and fairly reliable testing equipment, that thus comes within financial reach of smaller fish, probably their main target and thus main income. I wonder if the verifier can be misleaded in any way, as a kind of "loophole" chance that the designers overlooked. It's induction > weakening of its field by in the material induced currents, which are a function of the kind of material and its shape / size (within the fields reach). A same amount material as a longer smaller form has a higher resistivity than a shorter thicker form. That's why they need to 'program' the existing specific precious metal items / coins that are to be tested for real. But it may be possible to achieve a similar induced current along another combination of the involved properties. There may be a chance that at some point, the scammers find a mix that fools the tester. Of course, the material mix should be cheaper than pm's. Recent new technology is always a risk on this. At some point such tester may end up laying on a desk of a Chinese technician that has been assigned the job to see if there's a way to fool it. Fakes is their income, income is usually not given up easily.
Can they make a PM verifier that can detect fake kilo bars filled with junk? Not plated stuff like fake coins that have a thin layer of the real PM.
It's called ultrasonic testing - here are a couple of videos by Goldstackers [youtube]http://www.youtube.com/watch?v=tVjRSye8z-c[/youtube] [youtube]http://www.youtube.com/watch?v=rqcgV_kH9Ns[/youtube]
Surely is more of a preference but, ULTRASONIC THICKNESS METER GAUGE testers, if of a good quality... they are my choice... very very reliable.....
sellers on ali baba would have already started production of the testers, exact fake copies. These fake testers will appear just like the real thing, only that it has automatic adjustment and no matter what metal is inside, it will tell you what you want to hear, yep it's silver, yep it's gold.
with gold & silver being such good conductors of electricity, soon the ali baba's will implant GPS tracking devices into real gold bars. they'll have little ali baba's in cities across the world, most likely driving second hand google cars. They'll track every gold bar and not only get it back but everything else you have stashed.
