I think someone is having a laugh at your expense. Look at the right-most LED in the modified circuit. How could that possible be used for "extra long range gold detection"?
It's simply an LED with a 470R series resistor, connected across the battery!
The LED could easily work as described if you understand the physics in which LRL operates.
Qiaozhi, is a prime example of 'When Educated Idiots Speak" (WEIS) as authorities of something they know nothing about. Dell
That's so funny!
Please explain how an LED connected across a battery can be used for "extra long range gold detection"?
What physics process are the "educated idiots" not understanding here?

red led for power on
green led for detecting gold
No matter how the speed of light is high , Darkness is one step ahead .
It is obvious from the schematic that the RED and GREEN LED's cannot both be fully on at the same time (ignore the 3rd LED on the right for the moment). When T1 turns on (RED LED is on), and T2 is off (GREEN LED off), and vice versa. The 3rd (GREEN) LED is across the battery and will be illuminated as long as the device is switched on.
However, it states in the schematic that this 3rd LED is an "extra long range gold detection mod".
Explain that (if you can), without using DW's Hillbilly Science

These are all idle circuits. Do not spend your time in this circuit.If you have more information, you can easily build a metal detector

Pardon me but what makes this circuit a gold ions detector? I admit I am ignorant about electronics, but this looks like a simple pre-amp and amplifier like what is used for a VLF receiver. Is there something special about the antenna? Obviously there is something I don't understand. I am not trying to be contrary. I know ions travel through the air. I've seen devices that measure the polarity and voltage for negative or positive ions, but this does not look anything like that and I don't understand how this can tell the difference between gold ions and all others or any ions for that matter.
I know Dell Winders talks about using a crystal radio to hear static when near a gold deposit. I assume this device works something like that? Is the antenna some sort of ion chamber like Esteban posted? Must only select a narrow range for gold only? Dell says since the Mineoro can detect an MFD signal line it is not detecting ions at all. Maybe it is just the interference that ions create?
