Sorry, can someone tell me what metal detector is this scheme?

Thanks

Tesoro one.

It seems to be Tesoro

The image is labelled "metal_detector_drawing_01_silver".
As others have already stated, this looks like a classic Tesoro circuit.
It doesn't seem to be a Silver Sabre 2, or a Silver Sabre Plus. So it might be an original Tesoro Silver Sabre.

Well... you all are right, I drawn that circuit some 20 years ago ( wow.. getting old), the basic for it were the silver/golden. Never made it as pcb so there can be errors in it !
