Why the voltage regulator 337 is not installed

there is no reason

yes Toyo .circuit super scan.
How it works 5v regulator. Not connected gnd

+24v is the ground my friend on superscan and in most pi detectors.the circuit is correct and works very fine.

layout from super scan Looks good, double sided Version could be much smaller
but it is ok for diy project

i made a new pi from GS4 and Superscan ........PCB is 12.8cm X 9.5cm.

NEW SUPERSCAN PCB is 14cmX8cm

Αnd my new Duble PCΒ Bone above the other is 12.5cm X 5cm

Rospy PDK Detector is it a vlf pinpointer or LRL?

is a VLF Receiver .actualy is the receiver off HEATHKIT with more sens.

thank you TOYO
Do you have Data of the coils (inductace ,thikness of the wire. thickness of the ferrite rod)?
- the valeur of resistance that connected at pin 2 of 555 in circuit 680k but in pcb 470?
- in pcb the capacitor 100uf not placed?

thank you TOYO

coil superscan; 450 millihenry or microhenry.

450mH

think it is MICRo Henry not milli

@ TOYO
can you show NEW SUPERSCAN PCB is 14cmX8cm?

For clarification Toyo is this circuit a detector in its own right, or a receiver circuit where RX coil needs to be inductively balanced to a separate TX coil and circuit?

is a own detector like PDK

As mentioned earlier, we do not discuss either dowsing or LRLs (and that includes PDKs) in the Geotech forums.
