An outstanding product, especially for the silver stackers. Test dozens of coins and/or bars accurately in only a few minutes. Never get fooled again! No more chemicals, no more magnets or scales, no more filing. I am glad I decided to 'bite the bullet' and purchase this tool.

I received it quickly from Coin Supply Express. I read the manual and started using it and it is very easy to use and as far as I can tell verifies that metals very accurately. I used the main sensor and the bullion sensor and both worked great.
