It is used to adjust signal to pin 2 IC8 set it to voltage be about as voltage on pin 3 IC8, affects the potentiometer for treshold,I gave my device to a friend and I can not tell what's happening but I think that's what I wrote affects the adjustment thershold !

Hello to everyone. I need a pcb for this metal detector. Regards

nice that you have layout files, can you upload them please?

Which version is the deepest with 1x1m frame? Is the sniffer 71 deeper than dbp2010?
Apparently the first version of Wilhelm's book made mistakes. I read such news on the internet. Later, the tiles were modified by various people in the east and some versions had very great ranges. There are plots everywhere, and hardly anyone with schemas gives ranges.

Which version is the deepest
----
do you need 3meters depth on 15x15cm gold plate?

[Lam-part]

Do you have such a deep version? Means 3m catches a 15x15cm plate?

simple georadar. no electronics.

"Power MOSFETs have highly-nonlinear capacitances. For the new super-junction types, voltages 500V to 800V, nonlinearity can be severe, up to 100x. A new Coss spec, effective capacitance, comes in time related (tr) and energy related (er) forms, with a stated voltage, usually 80% of breakdown. It's a fixed capacitance that matches the FET's charging time or energy consumption. Older FET datasheets are missing these values. Anyway, I have created an instrument to measure these parameters and more, like Eoss vs drain voltage.
