LOOKING FOR GOLDSCAN 4 Schematic.

Your op-amp negative feedback copper spacing—what is it?
If the spacing is not reasonable, parasitic capacitance can form and cause oscillation.

Hello, I finally received all my components and have reached this stage of the build. Could someone help me with the adjustments for V1 through V5? Do I need an oscilloscope to set them correctly?

Initially, you can leave the trimpots in the noon position. After operation, perform fine adjustments using an oscilloscope, setting the frequency range using VR2.VR1 is the 0V adjustment for the oscilloscope probe connected to the TP pin.

Good luck… But I don't think it will work the way you're imagining, with people explaining how to adjust all the potentiometers. Judging by the board's appearance, it seems like you've simply populated it and are now asking how to "adjust" it. That's not the right way to do it. You have to populate and test the circuit module by module. Only proceed with the next module if it's working. An oscilloscope is absolutely essential.

Hi,

you can see it how you post your requests...
You haven't read the posts, apparently. Otherwise, you wouldn't be asking about the files. Everything you're looking for is there. If you had read them, you would have found it and wouldn't need to ask.

I'll say it again: I've read many posts on this forum, but I have my reasons for requesting the files here in a single post. Not everyone is a Nikola Tesla; I'm like everyone else, looking for a good metal detector to build. There's no need to get angry; you could have helped.

Hi Laith,

If you are looking for GS5 files, why do you not read those forum posts? Everything and much more info is there as well. You only need to read the forum posts.
It seems that you are the kind of person who want everything presented on a silver plate....but this will not work.

Who tells you that i didn't read all posts why you so angry

Go to page 41, message 602. There is .lay file from which you can extract gerber.

Im looking for gs5

[Toros]

Any one can give me Gerber files?

Where you get them

I had these boards produced at JLCPCB.com using the file that Eduardo1979 posted. The only modification was replacing the LT1114CN with a TL064CN using the Commander Mono Coil 11" coil. The ground adjustment allows for very good elimination of ferrous material.

As you can see in the video below, ground is at 50% and distinguishes ferrous material from a gold ring very well.

Hello, I hope you’re doing well.
Regarding the GS5 circuit you built — does it not require any special components?
Do the components need any modifications, or does it work as is?
