Link to thread about precious metals testing?

jmski52

I've been trying to find the thread where Weiss and someone else were discussing the types of precious metals testers, but I can't come up with it. I'm particularly interested in the device that Weiss has, and in the discussion from that thread. Can someone point me in the right direction? Thanks in advance.

Thanks, Johnny. There's another thread about the Sigma, but this is what I needed. If anyone has a link to the followup thread, I'd be interested in that one also.
