Where did you get that idea?
From Bob Fitzgerald?

Guess what? Bob Fitzgerald lied!
No electronic engineer built the circuit you see above.
Why would an electronic engineer install a filter capacitor backwards and take a chance that it might explode?
Why would an electronic engineer short out a resistor instead of connect it to a switch?
Do you suppose the person who built this circuit might be be fired for imcompetence if he worked at a real electronic engineering company?
The only electronic engineering in this circuit is the part that they copied out of the 8038 data sheet and application notes. Everything they did to modify it was a mistake (or possibly a joke to fool naive people into thinking they added circuits that can find treasure).
Fitzgerald says the
"Target Reflection Nullifier (TRN) feature shifts the signal line to the correct location and determines the size of the target".
This is a lie!
The TRN circuit they added does nothing except to lower the signal voltage 2/10 of a percent. When you switch it to turn on the LED, nothing changes... it still lowers the signal voltage 2/10 of a percent. The Med-Hi-Low switch does nothing unless you switch it to the low position. Then it causes the signal voltage to reduce by 3/10 of a percent instead of 2/10 of a percent. In other words, all of the resistors with switches they added to the application note circuit does nothing except to lower the signal voltage 2/10 or 3/10 of a percent lower than it would be if they didn't add the circuitry. This means the added circuits and switches reduce a 5 volt signal to 4.985 volts, -- an insignificant amount.
Then we have a set of 5 coils which are wired so no current can flow through them.
No electronic engineer would be caught wiring coils to a signal generator in that way.
This raises the question: Why are they there? To fool people so they will think this LRL is high tech?
Whoever built this is probably laughing at people who pay $1895 to buy it.
Let's review: You can buy the same 8038 function generator fully assembled and working for less than $50, then hook it up to your dowsing rods and antenna here:

So why would anyone buy this Vector Trex version with stupid circuits added that could explode for $1895?
Because they are stupid?
It appears no electronic engineer builds Vector Trek products. Incompetent people built this circuit.
They have stupid things added to a signal generator circuit, the same as products sold by other LRL salesmen.
This, for example:
