There are many modifications. Exactly according to which scheme your board was made. Can you publish it? The fact that you made the values of the elements visible only when pointing with the mouse pointer makes it very difficult to clarify the PSB scheme.

hello master,
Can you share the video of smd wave?
if you don't mind

What are the coil values you use for the device?

Best regards
Gurdal

did not collect.checked according to the scheme
TX - 11 MH, 50 Ohm
RX - 1.5 MH, 4 Ohm

[Toros]

or vice versa RX-TX

[Hinkri]

or vice versa RX-TX

TX is always more inductive than RX

[Toros]

You're wrong, my friend. There is no such detector in which the transmitting winding has a higher inductance than the receiving one. Your explanation makes me think that you failed to start the detector to work properly.

[Carl-NC]

In commercial designs I am not aware of a detector where the TX inductance is higher than the RX inductance. It could be done that way, and I know of one private design that did so.

[Altra]

One case I know of is the Minelab Soverign and Etrac. Each had greater inductances for the Tx vs. Rx. But these aren't normal vlf detectors.

Soverign TX 1000uh Rx 400uh

Most likely the coil above should be 1.1mH for the Tx and 1.5mh for the Rx?

[Toros]

The guy just confused the name of the transmitting and receiving coils. This can be seen in the diagram he applied.

But what about Garrett Ace 250-400 coils?

I don't know, and don't have one handy to measure.

As ArchibaldSTM states: the Garrett ACE 5 x 8 inch coil has a TX inductance that is higher than the RX inductance.
I have measured one using a Proster BM4070 Digital LCR Tester: TX = 2.5mH (3.7 ohms) and RX = 1.7mH (20.9 ohms).
