Hi Geo, glad to see you are still alive. Yeah, I don't know if it would work. Maybe just paint the ends of the ferrite rod as that is the hot spot. Right now my thinking is it might cause a lot of static from the radioactive decay. I still say it is a horrible idea to have the radioactity near your face.

I agree with you at all.
Before some years i found a ferrite inside a radio (constructionyear 195 that is a little radioactive and it is very very sensitive to gold and copper. Some times i use this lrl because it is very good for long distance (300m and more...)

Regards

Geo what does a little radioactive ferrite mean ?Surely you have measured the permeability of this ferrite rod, what is its permeability?Perhaps this receiver was used in the area of Nagasaki or Hiroshima and the ferrite accumulated a certain amount of radiation.

I don't remember the permability of this ferrite.
This story is before many years.... maybe more than 10 .....
Sure the materials for ferrite was taken from area near to Nagasaki ... or....
As i remember Geiger gave few beeps more than background.

your new pdk can detect buried 30 gold coin : (from 200-300 AD /Weight 210-250g / dimension 10x15cm - 15x20cm /at 130-170 cm depth ) from 10-20m away?

I never dig so deep to get a few coins, maybe is possible. The treasures I found with PDK-3 was hoards at 80 cm deep,distances of 40m.

this cave has simbols ONE SWORD (moorish) and a shield or skeleton head, people call this cave ,the cave of the moors, the PDK-3 gave me signals there,however the cave has a lot of tunels and galeries,and maybe some traps,

someone here know about treasure symbols on rocks?

it is very good to find a treasure at 80cm depth from 40m away , maybe can detect deeper target

i think (sword+shield+skelation) means a tomb of warrior around (In the direction of the tip of the sword maybe important)

I think is maybe a hide treasure left when moors run away to north africa, however other possibilities available,that marks are to identify something in that place

Hi Geo , Here 400nm UV can be using like Transmitter for more penetrading to ground , because E+ is high , But for Receiver will need special nm IR Led and when using Filter so
will remove other nm .

IR diodes has large bandwidth so you can find the suitable IR diode for (your) special wavelength (nm).

No all is wide Band , for example 700nm , starting from 650nm (gain %10) center 700nm (gain %100) and finish (gain also near%10) , so gain is like Pyramid ,
if here you use filter , so Pyramid will be more pointed but gain will decrease a little ....

Before years I buy one special filter (was very expensive) in XXXnm for use with Digital Camera this also is narrow band , and so I can See aura near big buried so like Lamp light .

Hello Morgan
lm beginner, can you tell me how to adjust pot.4M7.Do I have to have field test,or do I need to measure with multimeter.Please answer me.
Best regards

One of the photosensors that i use has bandwidth from 730 to 1120nm for a gain 10%.
Pin diodes has same or more width....
And of course there are and narrow bandwidth diodes....

Hi Geo , 730 to 1120nm is for find which metal , Silver or for Gold

With so wide bandwidth you can catch many metals....

In an infrared circuit for metals from what I have seen, I do not think you can separate the metals but I think you can increase the chances for some metals. If we place a led ir 1300nm I do not think it will be able to see only silver .. I do not know if agreed Geo?

Hello Kosta.
I don't like 1300nm..

This Morgan sensor will be useful to mark strong signals with my ionic rod and prove that it is real and can only find gold with Alonso principles of electrostatic rods unknown by many
