Teflon? Ekcellent stuff.
I am only not sure, maybe it can bring you out of sensomotoric ground balance?

Of course sensomotoric balance is compromised when not wearing rubber fishing boots.
But this is not important when we are not trying to maintain balance on a fishing boat.
When we are treasure hunting and we have a fully electronic long range multi-band spin-stabilised LRL, the sensomotoric balance is no longer needed.
This is because the electronic LRL will work even while we sit inside the helicopter with seat-belts fastened and fly to the location where it directs us to.
The only remaining problem with the Teflon boots is they do not become dirty because of their non-stick properties.
Dirt seems to simply fall off.
But this is not a problem...
It means I do not need to wash my Teflon boots unless I step in something that is very sticky.

Sounds very promising. Probably your Teflon boots are the same thing as NASA used for moonwalking?

Moon walking?
According to Rocketdyne's head of technical publications Bill Kaysing, the moon was never walked on...
But I saw people walking in water where fish are caught with my own eyes.

hi to all
Whether the device is used as the Earth's magnetic field sensor.Whether it is for the detection of metals located in the basement can be used remotely?

I wonder what year is the number of this Elektor.?

I am wonder too.
I even cannot find where I am posting first time this circuit here on forum. Mesy not decided to got us link.

Thanks J_P.

With two glued ferrite antenna rods we can get of about 40cm long ferrite antena.

Pistol can be build by this antenna and proposed circuit according this Erevnitis design:

[mesy64]

You use ferrite rod for ferrite antenna say 10x200mm, but in rule "the larger, the better". You can glue (with glue for ceramics) two ferrite rod together as on drawing. CuL wire diameter less than 0.2mm. Wire can be wound iregular (in zig-zag manner).

Final inductance of about 57mH. I cannot say how much turns, it depend on ferrite you use. You need to wind first 100 turns, measure inductance and calculate approximative number of turns.

tank you very much dear wm6
Both the wire on the ferrite is complex?
What material is the orange?
Ferrite is the longer you cause more sensitivity???

[WM6]

No complex, it is very simple. You first glue both ferrite together and then put it in adequate "tight" plastic tube. Then the coil can be wound on plastic tube - not direct on ferrite rods. Done so, you can make some tunning to the best signals by moving ferrite rods in tube back and forth.

"orange" is coil wire (Cul windings) presented in cross section.

Yes, with longer ferrite you can get more directivity which in results is same as more sensitivity.

[teknoloji]

I still wonder. What year and number.

This is not an advantage to connect the ferrite NS polar opposite in a row.

I think this just might be the sensor.

should we read Elektor article.

The new metal detector will be revealed during in the soil?
If the new metals in the soil can not hide the obvious?
Tell me how to test the circuit?please
waiting for yoy
whith respect

Schematic is modified and I dont know exact source anymore, but as seems source can be from Elector.

It is about ferrite antenna rod and not ferrite ceramic magnets, so NS polarisation will not take effect. My first comment should not be understood that it is obout some sort of Earth magnetism sensor. It is about Earth signal sensor.

I am not sure that I understad what you are trying to say.

Soil is not a barrier for Earth signals of very low frequencies.

You can sense only bigger metal (or metal ore) deposits in soil on basis of changing Earth signal magnitude here converted in number of LED pulsation.

Hard poluted soil with bigger metalic parts mean unwanted disturbation during detecting.

Hi WM6,

When you originally posted this circuit, you said it was an earth signal pistol which operates at a frequency range from 666Hz to 3066Hz.
I see three frequency settings available in this circuit.
These are ULF signals which are observed as either natural or man-made noise signals traveling through the ground and atmosphere.
Because there is a ferrite sensor, we can expect it will be more directional than a plain loop, and it is much more directional than a telescoping antenna.
But since this is a receiver, we depend on these earth noise signals in order to make detection.
If there is no earth noise signal then we detect silence.

I have two questions:
1. How do you use this for finding a signal?
Do you experiment with different frequencies to see what works best?
Do you look for some frequency that has a lot of noise so you will get some detection?

2. How do you use this for finding buried metals?
Has anyone determined that detecting the direction of this noise signal will tell you the direction of buried metals?
I look at the antenna, and I see that when you point it at the source of the signal, you can expect to find a null signal, or silence.
Does this mean we look for a null to determine where buried metal is located?
