The Moodz detector lives !

Excellent work moodz. Go ahead.

What sort of coil did you use, mono "bunch" winded or center tapped (pretty unbelievable with 5 micro seconds sampling time)?

I am not able to hear any signal signal voice in this video - probably you use earphone?

Hi WM6 ... I have grown tired of secret squirrel detector projects so very shortly I will gather the documents and publish my design for a kickass PI detector.
This detector can resolve X and R signals from a MONO coil in the time domain ... and using only two samples ( this provides ground rejection AND opens the door to discrimination on a PI )

See Pix below ....

Thanks guys ..its a bunch wound i think commercial 11 inch mono. The ground and emi resistance is due to ideas i have published here ;-) before ...sorry about the sound it was coming from headphones into phone cam. Will post another with better audio.

Hi Moodz


Video audio is very weak but I got it by using max volume on my end. 50 cm (19.5”) is outstanding performance. Can you say more about Ground resistant and EMI resistant?


Thank you,
Chet
