The only practical way to check if there is a specific frequency for gold is to try different frequencies. However, as I have already said, we must keep in mind that the sensor stage is practically a high gain high pass filter, therefore it amplifies the frequency of 9MHz more than a 4MHz frequency, for example. When using the 4MHz frequency, the value of C13 / C14 must be increased to achieve the same gain. Or you can increase the gain in the stage display.
