Hi Guys I am developing the following gold and silver tester, I'm looking to make it affordable, so less than a couple of hundred dollars. I'm checking if people would be interested in it. Your feedback is very welcome. Thanks
looks massive…I guess the size is not as portable as ppl would like to carry around and setup must need a flat surface as the pendulum needs to do its movements… on a positive note…it is nice display of authenticating your precious metals…bummer it is just for coins at this stage…
