Default PD again...

Of course you would need to program a PIC to process these four signals properly before causing the 555 to make beeps. For example, when the static magnetic sensor detected magnetic north, then the processor would make a correction by subtracting the magnetic north influence from the signal so it you would not make a mistake to think this is a gold signlal. And the processor should subtract broadcast RF and modulation as well as 50/60 Hz power signals to remove EMI noise from the treasure signal. Then the remaining treasure signal could be easily processed to determine exactly what metal you detected at what distance and how deep in the ground, as well as it's weight.

The resultant "cleaned" treasure signal would be so good that you could call the quadro-detector the supreme LRL.
Think so?

Hi J_P

I think we should join the team again in the Pistoldetektor project and make one last atempt,this time only to upgrade the PASSIVE RECEIVER in the pistol to the limits,of course someone here maybe have enough knolenge to do this(Esteban) but...
As you know the fast LRL results in Alonso PD result in special balance Pass. Rec. + Omega,but it was told by Alonso that Pass. Rec. working alone is able to detect treasure size many meters distant,SO LET INCREASE THIS P. RECEIVER TO DETECT ALSO THE SMALL TARGETS,lets try diferent antennas ferrites etc...
The specific electromagnetic resonance of PD is 62 KHz,this is a filter,the results i get is always Gold,silver,aluminium(sometimes) No bronze,plumb or iron. So we have one LRL,only need to upgrade Pass. Rec. for coin size objects. Not forget the Passive Receiver works automatic,no need the critical adjustment,this will be good for all of you in your TH searche.Using the heatkit only for pinpoint the objects after dig.

Regards
