Doing my own research I just found that the "Precious Metals Verifier machine" shown in this video can only penetrate 2 mm deep into the bar, that is even if you use the bullion bar wand, 2 mm is almost nothing unless you have coins or very thin bars, but if you want to test 50oz or bigger bullion bars, this machine will not penetrate more than 2 mm deep into the metal. In my own opinion, the "Specific Gravity Test" would be the best way to go if testing big chunks of silver or gold.
+cubaniton74 holy cow it doesn't even do kilo or 100 oz bars which are very thick..this is a huge drawback...im not worried about losing 17 bucks on a silver coin but dont wanna lose 1600.00 on a lead filled 100 oz bar.. i'll buy one when it does 100 oz silver bars..
yup here is info from the manual... When measuring pure gold and silver sub-surface metal changes up to 2 - 2.5 mm (80-100 mils) deep can be detected. Sub-surface metal change up to 4 - 5 mm can be detected for 22k gold, 90% gold, platinum and palladium, and sub surface measurements to 3mm for rhodium.
They have wands for larger items. They now have a pro version which resolves the remaining few deficiencies. I guess I'm going to have to breakdown and buy the pro version. Very cheap insurance.
after reading some of the comments regarding that the device only reads 2mm into material after reading this im prob better off waiting until they create a device that can read 100% of the coin or bar etc may not be in my lifetime but tech is always moving forward.
Unless you buy kilo or bigger bars then this device should work just fine. From my understanding the Chinese haven't produced a fake coin that could beat this machine.
There is a device that can do that, it's called an XRF (x-ray fluorescence) gun. This is $600, an XRF gun is $20k+ It absolutely would not be worth it for someone to hollow out a silver eagle to put a .5mm thick wafer of some other metal in the middle. This will 100% verify the authenticity of coins and bars up to 10oz. This is great for someone who can't afford an XRF gun, which is basically all collectors and most small independent coin shops.
Hi I received my unit today, and it seems to work good but are you familiar with the reliance of these units, I have tested gold eagles this evening and 0.999 s silver,and everything is as it should be but i recently bought (8) south east refining 1 oz silver bars, and only one of the bars has the black bar outside the brackets to the right, I used the wand and same result. I weighed and and used a rare earth magnet and it checks out, I have about 40 of these bars, and nothing about it stands out, except that it is slightly outside the bracket, any tips or ideas? Also do you know if the St. Gaudens eagle test similarly to the modern AGEs?
one Chinese counterfeiter thumbs down this video
Two did

should be ok for coins
2 mm is still pretty good for most items.

so where can I get one ....... anybody know .... got a link someplace ?
Where we can buy this ? I don't find in amazon
Do you test one side of coin or both??
Where can I buy one in the UK?
great invention... can be improve for bigger bar... but meanwhile is good enough for basic check u got the right one..
Whats the physics behind it?
About time ..........hope it works on jewelry and odd karat gold and silver letting you know what percent it is.

Wow very cool. Wonder if it works on jewellery ?
oh if i had one of those hopefully any decent jeweller should have access to one

were did you buy the one that shows up outside the bracket? I would take it to a coin shop and have them take a look at it to make sure it is real
when this does 100 ounce silver bars im in..
