this help?

Thank you dear kt315

Hi everyone, I’m having trouble finding a White’s coil at 6.59 kHz for this project. Does anyone know if Chinese copies exist?

Wouldn't it work if you get any coil, a White made maybe for the sake of the plug, with higher frequency and just add more capacitors on the board to tweak it to the desired frequency? For some reason, I'm assuming the tuning capacitor is inside the coil. Otherwise, I would say just replace the tuning capacitor.

That was me learning through asking questions. Anyway, I think these models of White's run at 6.59 KHz : XLT, DFX, Classic series, TM 808 and coinmaster (I believe Google AI can name you more models that run at that certain frequency) Some of which you can have coils for from Detech or Mars websites

Also, you can order any specific coil from nexus official website but I think it's going to be pricey not to mention the coil plug might be different if you don't ask them to install a specific plug. So, I would make this my last option. Good luck!

Hello
Dear All
Please share a correct pic from nulling TX and RX.
I only could find the attached, is that true?
I can not find a correct picture on scope for adjusting phase TX and RX.
Pin-6 from U1 = Rx
Collector Q1 or Tx pin = Tx

I'm confused... what will it detect, and what will it NOT detect? Do you have an oscope?

Edit: Try reversing the lead connections to the RX coil.

Good evening, Mr. Carl, as I already wrote on the forum, gold is not detected; any metal can be discriminated. It seems that only aluminum, iron, and silver are not detected. The two sensitivity and discrimination potentiometers are not working. I don't know where to look for the problem.

Hi. There must be a phase shift in the device. Set the ground balance regulator to the middle position and by selecting containers up or down on the receiving coil, achieve a complete cut-off of the reaction to the ferrite target. I hope I explained it clearly.

Yes

Are you saying it will detect aluminum but not iron or silver coins?

Hello everyone on this forum! I've already asked the Gurus for advice on my IDX Pro, but I haven't been able to resolve it. My IDX Pro has this problem: In all-metal mode, it works normally except for sensitivity. However, in discrimination mode, it discriminates against all metals except aluminum, and turning the sensitivity and discrimination knobs has no effect. I've tried checking the components, but haven't found a solution yet. Thanks for sharing your opinion.

My dear brother, if you want to install a VDI display circuit with the IDX Pro metal detector, then you will have to do programming in the microcontroller. If you can do it, then you can add a VDI circuit. And for double tone, you can get the circuit and information on this forum. Can you help me? What is the range of your metal detector and what is the data of your coil and can you tell me how to connect the potentiometer with the circuit? I hope you have understood. Thank you.

i am ethnical ukrainian, but my mother is russian. why you ignore all russian? this is my job, has two tones, i have 50 pcs of boards
for years ahead selling.

I'm sorry my brother kt315 the was a little miss understanding, i love Russian and Ukrainian they are providing real value to this forum and to the world and i hope your conflict gets resolved peacefully real soon, Also i remember your help with my dp2 it was priceless and a life saver. i was only talking about the RU language that i don't understand that's all there is <3 .
PS: Great job with those pcbs looks like an excellent quality .
