I'm going to be buying a precious metals verifier and I'm considering the Sigma PM Investor. Can anyone who owns one or has experience with one give me their opinions, both positive or negative?

    PMV - precious metal verifier. Love mine, , you'll want the three sizes of wands with it. a good reading is always a good reading, a bad result requires different attempts to confirm.

    When gold and silver move together, it signals the coming end of fiat money.

    I have the basic machine with three wands, works for me, friend has the pro, he likes it, a little more involved and complicated, but he likes it. Two of the bullion places I sell too have the advanced version, but they also have two ( i repeat ) two XRF guns, so they are covered.

    Sigma is a great machine, but it's just one step to positively verify, always weigh, measure and acid test. (If you don't have access to an XRF)

    The counterfeiters are getting better every day, some stuff will slip by the machine, but the more you handle and work with PMs, the easier it will become.

    I finally bought one, and it only showed 1 positive on a known fake, out of 100s of tests.

    Worth it IMO.

    I have a couple gold watches.
    The local coin shop has a Sigma tester but said it doesn't work well for jewelry.
    Coins if it's in the right program he said it works great.
    Another friend has a Kee tester.
    His results match my acid testing results.
    I questioned my results because my acid is about 2 years old.

    i'll rephrase

    only acid test scrap gold

    use the acid test just on scrap gold

    something like that
