[1] Sigma Metalytics PMV PRO - Introduction & Review

We take a look at the new Precious Metal Verifier PRO from Sigma Metalytics, try it out on some real and counterfeit bullion items, and do some comparison testing with the original PMV.

**NOTE: the correct resistivity of gold is 2.2 x 10-8 Ω·m

Even the weight can be counterfeited for example the metal can be hollowed out inside and another non Gold and non silver metal can be put inside, we need a thickness scanning device for this

[gblargg]

You mention an XRF tester at the end but even that can't detect plated items, since it only tests the surface of the metal. The Sigma PMV is a fabulous tool.

Excellent informative site visited by interested and experienced precious metals collectors. New sub here. Thank you.

[catdogdad]

have there been any known complaints about jmbullion or apmex selling fake coins

[mtube]

is there a reason why a real silver eagle or the real silvertowne bar give resistance reading higher than the published 1.59e-8 ohm for silver?  The PMV-pro was yielding reading of 1.73-1.76 for silver eagle and 1.64-1.75 for silvertowne bar.  These resistance is closer to copper, 1.68e-8 ohm, than for silver.

I'm about ready to quite buying pm's. This is getting frustrating. I just spent 800 bucks on this damn pm verifier and now I learn it's not that great. And everyone always says to weigh it so I bought a scale and my silver eagles are never what they say they are supposed to weigh on Wikipedia. I have bought all my gold and silver from APMEX and local coin shops but my sigma will say the coins just barley qualify as real being almost outside the box and like I said my scale and also my caliper come up with different measurements and weights then what it's supposed to be.

Some how this unit seems more complicated to use that the original Sigma Metalytics Precious Metal Verifier which produces fairly accurate results. Still expensive at $989 but less than half the cost of the PRO.

Hi there, will a Perth Mint 1kg bar fit under the large sensor? It appears it will, I just want to be sure before I buy - I need to ship the unit internationally so an error is not an option.

[petero]

Very very good video showing the difference in accuracy in testing PMs with these two devices. This one definitely seems much more accurate. Even still, to be 100% sure I would always recommend an xrf scan, especially with gold!

[objvst]

Can the unit verify a Roosevelt Dime, Jefferson War Nickel, Washington Quarter, Kennedy Franklin half, or Morgan Peace dollar? If the market someday crashes and silver and gold moves to its actual value possibly showing on the US Debt Clock these will be hot items of exchange for products or services. Everyone will want to own one, all business will use them? Please test if available on released SMPro. Thank you so much.

[leoguy]

Owned two of them and both times need to be returned for service.

[ag]

So my $575 tester is imperfect, just great. My confidence level testing is not good

[pmlover]

Appreciate the informative video. If I can't afford the pro version, do you think the original PMV in conjunction with the scale can replace the pro? In other words, are there known instances where something passes both the original PMV and the weight/scale test, but fail the PMV Pro?

[chrisabrams]

Do the electromagnetic waves damage or affect the precious metals at all?

[yokosaw]

Do you know why the 90% US silver coins are divided into three different groups by years (pre-1900, 1900-1945, and 1945-)?

I thought that all 90% US silver coins regardless of the year are the same alloy mixture (90%silver and 10% copper).

[ch.wey.]

But at 8:14 if you would have used a bullion wand? Wouldn´t it had detected the fake one?

[abelguy]

Will the thicker high relief slabs fit in left sensor ?

[LOL-hort]

I have perth mint 10g and it didn't fit the smaller sensor with its cover on. Is it a red flag? Also when tested, it passed through resistivity test and the density test but not the surface test. The dealer told me it happens when I have the cover on, but it seems like your gold bullion passed those tests even with the cover. Can you please help? I only have so much time if I should return it

[dalepres]

Seems like the channel and the web site are dead; hopefully the youtuber is not. It was good idea but appears the owner wasn't able to stick with it. Too bad; it would have been a good channel and good site.

[dougiequick]

Who else here wants to torture counterfeiters? Waterboard em, Electric shock, bamboo slivers driven between their fingernails submerged in ice water? Staked to ant colony?...anymore suggestions? Oh yeah my favorite....tied to a stake naked and allow anyone that got sold fake bullion to Stone them with said purchases .(I KNOW what I am aiming for!) ...although some of those large bars might be lethal I don't know....I don't want death on my conscience ...a lot of pain though? I think I can live with that
