Great, epitopios you get my Cristmas present at post #6 (Signal Transmiting Station - to combine with CS33XD).Originally posted by epitopios View Postdear WM6
personally , I need 100 meters only !!!
for me its enough , what about it ??? what can I do ???
Cristmas are close , not only for me but for all the world !!!
friendly , epitopios .73s
It is not really 100m in soil, but 5m for bigger targets or deposits in soil can be achievable.
And that is far enough for me, because I am not willing to dig something so deep (usually no more than 30cm).
Happy hunting!
PS: suggested additional reading:
There are product alike to CS33XD from other company, you need some search with Google.
For those PM asking: I haven't working schematic for receiver as CS33XD only partial schematic from some patent:
about CS33XD equivalents from other manufacturer:

dear WM6 , I think you misunderstood me , I dont want 100 meters deep (ouaou!!!) but from distance!!! About depth 2-3 meters are enough !!
I hope I was understandable.
thanks in advange ,

to detect something small from 100 m distance remain only a science fiction.
Maybe 100m can be possible if we are speaking about bigger (ore) deposits in soil.
But why you need to detect something from such 100m distance? I suppose you are mobile man, so you can walk and detect bigger targets from real (say to 10m) distance. In all cases you need to go in vicinity of target, after or before, no matter, why than bother with dreams?
So I think 5m distance for bigger target is far enough if you walk around. And, as first, it is real with proposed device combination. All others are only sweet dreams.
There is nothing wrong with dreams if we need to go out of crude reality. Only it can be problem to go back.
REMARK: Proposed Signal Transmiting Station must be put in RF EMI shielded box (with antenna outside) to avoid uncontrolled feedback self-oscillations and interference.Global capital is ruining your life?

L2 is (outside box) antenna coil.Originally posted by epitopios View PostWM6
you wrote at post #6 about L2 (turns , diameter , mH , coil and ctr)
What about L1 , some more imformation ??
friendly , epitopios 73s
L1 is (internal) inductor and you only need to follow given inductance of 72mH, no matter of shape (try to keep small dimensions), Nr. of turns or wire diameter (use wire between 0.1 and 0.2mm in diameter).
TIP for L1: you can use apropriate (regarding L) inductor from an old relay (without metal core) and adopt windings to inductance of 72mH.
REMARK: Left small hole in box for final subsequently C2 Freuency tunning by using CS 33XD from distance as field strenght metter.
If one is thinking that more power is needed, then other mono amplifiers module (like VMA2015 15W Mono Audio Amplifier Module) can be used:

In this case circuit before C3 remain the same and circuit (except properly incorporated C11 and L1 - which are placed instead of speaker) after C3 replaced.
Warning: do not use such excessive power near urban area because of very disturbing EMI.Global capital is ruining your life?

Hi WM6.
Please can you email me a photo from you???
Really i would like to see you because you are so negative!!!!!!!
Regards
why do you need my photo, I'm not so photogenic like you?
Probably you intend to show my negative photos to scare kids there around?
But to be fair (I saw your picture here in public), so befits, look at!
This is one of most positive photos of me, I was able to find:Global capital is ruining your life?
