Buildable machine close to the GPX-5000

[Gunslinger44]

Guys, I've built a Sniffer, and it works beautifully, but I am looking now to build a gold nugget finder, and no I know there is not such thing as a gold only machine, but I am looking for something close to a Minelab GPX-5000

No one knows this? Carl, can you chime in?

religious aspect again. no issue.

I don't think anyone here has the schematic for the GPX-5000.

He should ask ML

Once I heard something about MMP Gold, hahahaha

I understand the GXP-5000 that is highly dependent on an advanced processor.
Therefore without the firmware of that processor we can NOT build this.

Maybe check the SD-2200 which still uses analog/digital circuits and not a processor.

best speed processor

best discriminator ferrous-gold

Its actually good to know Minelab was able to protect their secret, though it's annoying to me because it means I can't build it. There is the Bulgarian "Pulse something" which claims to be the Bulgarian GPX 5000, does anyone know if that thing is any good in real life?

as far as I know there is no complete PI project for sub gram nugget hunting in mineralized ground

the original Gold Bug (none discriminating VLF) schematics are out there

Lobo is a well tested mature project over on MD4U.RU unfortunately you now have to register to view attachments.

We should start such a project here.
Better than the GPX.
His name "Goldsucker" or "Gold*****"
1Gramm Goldnugget-80cm depth

Just that much 1gramm goldnugget ..80cm ?
