    I'll offer again, but you could rent/borrow mine if you just want to churn through your stack

    Much appreciated bud, looking for one on behalf of a fellow stacker.

    Just send his stack to me and I'll test it. :)

    I offered a PMV first so by rights the stack should come to me for testing, yes?

    I guess so, plus I don't even own a PMV.

    Much appreciated bud, I've been saying the Sigma Pro is the way to go for silver testing. Harder to spoof.

    Gold standard in my opinion is scales, magnet, dimension, appearance and Sigma followed by XRF when possible.

    First time I see a report that the PMV doesn’t work. Does this mean the bar has patches of gold in it? I noticed that with smaller coins, such as half oz, it doesn’t detect that easily.

    Sigma PMV original model has been shown to be spoofed a while ago, hence the updated PMV Pro which has no reported issues thus far.
    It means the alloy matches the electrical impedance of gold close enough to pass the test. Yes smaller pieces always have trouble testing, big headache with 0.5g and 1g coins, they're undetected.

    Thanks but doesn’t the PMV Pro also uses electrical impedance to verify?

    It has additional parameters I believe such as weight and dimensions. Harder to spoof all three at once. Highly recommend using scales and vernier calipers when using the standard Sigma

    I personally rely on my old Sigma PMV unit more than my judgements... but when you're buying large bars like that I normally move the bar around the PMV ensuring all aspects of the bar reads the same thing...then again, if the bar(s) that you're buying doesn't look that legit/right then it's time for me to walk from the deal..

    As to that 'goldbugs guy, I hv second thoughts of his story as he's the seller and why didn't he pick this problem up when he purchased them... mind you they're about 8 of 20g bars.... surely he had the intentions to sell these fakes online to shorten his losses...so, what happens next?! He's just going to bare the losses from these 8 20g bars?!

    Was thinking the same, seems to me like a dodgy seller covering his tracks. Probably got them on AliExpress originally.

    I didn't want to comment and and add to your WTB thread, but it's well and truely riddled now so might as well comment. :)

    Is it just me or does the bar look like it's not sitting on the PMV (more so the table pic compared to the wand pic).
    Maybe there is some Au under it to give a true reading for the pic.
    (Also, straight off the bat the bar it too thick, FYI)

    For what it is worth i have owned the original PMV and now own the PMV Pro.

    The PMV Pro to me is a much better and more informative unit.

    It costs a little more but with the increased cost of gold even if it saves you from buying 1 oz of doggy gold it has paid for itself

    Plus it gives me piece of mind when buying new gold coins that i am uncertain or familiar with

    I find its fiddly for really small gold coins but does well for 1/4 Oz and above. Great with non capsuled coins like Pre 1933 USA Coins, 20 Francs etc as they fit nice on the main unit without needing to use and muck about with the wands. Also really good with 0.5 Oz Capsuled coins but best with 1 Oz
