I just read the FAQ from Sigma and for silver bars like 10 oz and with the bullion wand you can get 3 mils deep by checking the front and then the back of a 5 oz or larger bar. The bigger or thicker the bar the more room for a insert to hide. Thick bars is where the Pro series seems to pay for itself as it comes with a front and back probe with improved ability for depth. I dont have one but have been studying them for a while due to the cost. As you mentioned if you find one fake gold oz it has paid for itself.
Great video, thanks for sharing. The Sigma is a must have tool as far as I am concerned. While I dont rely on any single test, this tool when used with other checks gives me confidence the pieces I acquire are genuine. LIked and subbed.

Sir! Where are buying your gold and your tester? On the face of it it seems you’re paying too much.
