ion gold detector

[Qiaozhi]

After looking more closely at the link provided, I now see in English that it is claimed to have been detected at 4m distance and 20cm depth.
Even though some of the posts have a translation link, these do not provide any further information. The person commenting is also casting doubt on the Mineoro ionic theory.

So, questions 2 and 3 still require an answer.

Hopefully both Dave's and my own questions will be answered quicker than the one we're still waiting for from Dell, which concerns explaining the physics involved in obtaining "extra long range gold detection" by simply connecting an LED across a battery.
