The last scheme you give PCBs

maybe this help but chage the values

This thing works very good.PCB is old with an additional placed parts.

Very much about this device ! Lots of pages it seems confusing !
Concrete i need the correct number laps winding wire RX and TX I have one which broke cable ...

RX 130 turns 0.2mm
TX 30 turns 0.55mm
Use the pattern shown in the coil photo, and make the shape of the D like in this photo. Use old coil dimensions from your broken coil, it will be good.
You must know what are your tx/rx resonant frequencies for this detector in order to tune and balance the search coils.

DB,

i had released simplest LC generator schematic for checking VLF coils on resonance, for doing global coils' base for/from people.
i gave this project for geotechers, but they are sleeping in the bed and do not want wish appreciate my job.
they just want to waste money on cigarettes, not on the testing. my board gives TTL level signal and can be connected to any old and modern
frequency meter given you good lab instrument.
i again up the listing. https://www.ebay.com/itm/333336310236

do not answer more those people. you will be confusing again.
let them to buy that for 999USD https://www.ebay.com/itm/METAL-DETEC...3834%7Ciid%3A1

FOMA WRITES
Резонансные частоты должны быть разные. Чем и обеспечивается нужный фазовый сдвиг на Rx. Основная частота от которой все начинается это частота генератора, то есть частота на обмотке Тх. Ее делаете подбором витков Тх.
Не обязательно тютелька в тютельку. Плюс минус 200-500 герц.
А затем с помощью генератора делаете разницу на обмотке Rx, так же с помощью витков и конденсатора 33Н, уже от той частоты которая получилась на Тх. Для чистоты измерений обмотку Rx вместе с нужным конденсатором , который затем вставляется в плату лучше подключать отдельно от платы, и с готовым кабелем. Разница 450 -500 герц.

translation in your vaterland language

Resonance frequencies should be different. This ensures the necessary phase shift at Rx. The main frequency from which everything starts is the frequency of the generator, that is, the frequency on the winding Tx. You make it by selecting the turns of Tx.
Not necessarily top to bottom. Plus minus 200-500 hertz.
And then with the help of the generator you make the difference on the Rx winding, also with the help of the turns and the 33H capacitor, already from the frequency that turned out at Tx. For measurement purity, the Rx winding together with the desired capacitor, which is then inserted into the board, is better connected separately from the board, and with a ready-made cable. The difference is 450-500 hertz.

sincerely DB and have sunny day there in your Flo
