Ghosts Gold same thing

How good is it at detecting ghosts?

Yes - it will detect ghosts about as good as it detects gold

Hi MIJ,
It seems you found the same as what other builders of the Zahori found.
It detects charges in the air, but does not detect treasure.
You are able to detect the faintest of charges from combing your hair, or any other source of static charges.
But your buried gold and silver do not produce a static charge that you can detect.
But also remember that I have seen no example in this forum where an experimenter built the original Zahori design without modifying it in some way.
The original zahori circuit is a very sensitive static charge detector.
It is so sensitive that it has an electronic provision to drain any charge from the antenna 50 times a second to keep the charge from building up too strong where it could damage the semiconductor that is detecting the charge it collects.
It also has a sample and hold module which will remember what charge it detected while the antenna is being drained and preparing to take a new sample from the air.
Most of the projects I see people build have either deleted these features or modified them so they cannot work.
And I see many builders add on additional control knobs to make adjustments in the circuit that were not intended to be adjusted.
Nearly everyone who built the zahori, modified it, then after their modifications they say it does not work to detect treasure.

Of course, Esteban says it is possible to detect buried treasure using the Zahori.
It seems you have identified the question... how to make the Zahori detect treasure?
Some basic theory of detecting charges in the air:
If you are not drawing in air samples to check the charge of particles in the air, then the ability to detect a charge is related to the surface area of your charge collecting sensor.
This means a larger surface area will be exposed to a larger volume of air whereby it can collect a charge from the air.
But large plates or dishes are not desirable for a portable detector tool. So we have small versions as you see in the telescoping antenna.

A second principle is that when you are outdoors trying to detect a charge, you are grounded because you are standing on the ground.
The metal box you hold in your hand is also grounded by conduction through the saline liquid beneath your skin, so you can consider all your body and the metal zahori box to be connected to ground.
(This can change indoors, but we seldom go treasure hunting indoors).
Any charge in the air can be affected by your body moving through it, which brings a ground potential up to nearly 2m height to create an artificial ground in the air.
The part of your zahori that is not grounded is the antenna, which is insulated from the metal box.
The antenna will have whatever charge it pics up from the air around it.
Some of this charge will be from the negatively charged ground that you are conducting to the metal box.
But when the antenna is extended, the end away from you has penetrated through a voltage gradient to reach into the area where an air charge can be sampled.

It is as you say... the antenna can pick up charges from the sides as well as from the front. In fact, we expect it to pick up more charge from the sides than the front, because the surface is greater.
The front only has the diameter of the antenna (a few millimeters) while the sides have a surface that is over 3 times the diameter, over the length of the aerial.

We see some versions that show the antenna placed between two similar grounded antennas.
This greatly reduces the amount of charge that is collected, but it allows the small amount that is collected to become more directional.
This arrangement will collect more charge from the front, top and bottom where there is no grounded conductor so close as there is at the sides.
Another configuration is to place a grounded dish around the antenna so the antenna protrudes from the center of the dish.
This can have a focusing effect which causes negatively charged particles to congregate toward the antenna.
Of course, you could electronically charge this dish to become charged either positive or negative in order to repel particles that are charged oppositely.
(This is the principle of the Ivconic charge detector antenna designs).
But remember, neither Ivconic or any others who built the zahori or charge detectors with these kind of antennas ever located any buried treasure.

As far as modifications, there is a lot that can be done.
But in order to give advice for modifications, we would first need to know the circuit diagram.
This is because everyone builds different variations of the zahori.
We see even in the variations called "mini zahori", there are further modifications which nobody really shows the exact circuit diagram that is being used.

For your questions...
1. It is relatively easy to add on a buzzer circuit that can be adjusted to beep when the circuit finds a signal above a certain level.
This kind of circuit can be added as a separate add-on that does not influence any of the existing circuit in any way.

2. A different sensitivity knob is not needed except to add a knob along with the new buzzer circuit to set how strong the signal is before it beeps.

3. Antenna for more range detecting static anomalies begins with surface area.
But range of detection also includes directional properties.
When the optimum size is figured for an antenna that is not too bulky, then the next consideration is how to make it as directional as possible.
This approach is only for increasing the range at which you can locate a charge anomaly in the line of sight directions from the antenna.
There are other concepts of more range that are concerned with detecting other things than charges that are in the air or on the surface of objects in the line of sight from the antenna.
But these other concepts are not charge detecting concepts.
A ferrite antenna usually is used to tune a frequency in the VLF or MW range, similar to AM radio broadcasts.
Ferrites are not used for detecting static charges that we look for with a zahori.

4. Is it worth it to modify the original circuit?
It really depends on what is in this original circuit.
If you or Goldfinder can post a circuit diagram, I think some of the modifications can be done fairly easily. Others maybe not, but it really depends on what parts are in the circuit, and how they are connected.

If this is the original zahori circuit unmodified, there are some very interesting features in the cmos antenna-unloading switches and digital filter that could lead to some strange experiments with minor modifications.
Other later variants of the original design without these features do not have this opportunity. But these "interesting features" would be only for theory experiments, not for treasure hunting.

Hi MIJ,
The circuit you show does not look anything similar to the Zahori you described above.
This schematic has a single field effect transistor with only 5 components and a meter. and a battery attached.
The images of the detector you showed have an adjustment pot, a switch, two 9v batteries, a trimpot on the board, 3 transistors, an IC, and a lot of capacitors and resistors that I don't see in the schematic.

This schematic is not a Zahori.
It is a simple charge detector with a meter connected, without any switches or control pots, or extra transistors.
Maybe there is an error in the schematic, or in the photos that you showed?

Hi JP,

No this is the one Goldfinder sent me “hummm maybe he is having some fun with me?”

I did think myself that it looked completely wrong.

Come on Goldfinder have you got the schematic?

Hi MIJ,
From what I can see in your detector, it appears to be a basic charge detector that has provisions to keep the power supply extra stable.
Just guessing, I think it probably has a very high impedance transistor that is controlled by whatever charge is picked up on the antenna.
So when you get more charge, the transistor passes more current through it.
Then there are probably 1 or two more transistors that amplify this first transistor current strong enough to drive the meter so you can see how strong of a charge you found.

If this is the basic scheme, then I can think of one easy modification that could be useful.
If you need an audio beeping or an LED to light up when the signal rises above an adjustable setting, then this circuit could be added.
Of course, the utility of this kind of circuit will only free you from watching the meter while you are scanning for charges.
I suppose that could be worthwhile if you are planning to spend a lot of time using this detector.
This kind of beeper/LED circuit can be attached the same place or near to the meter in the circuit.
The beeper circuits can be made to consume very little power except for when they are beeping.
But we will need to know the voltages that are present in the circuit before any beeper is soldered in.
It is something that is better done by a technician who has the detector in his shop where he can take measurements to find the best way to wire it in.

Something else to consider is maybe you might want to investigate more about what does detecting charges in the air tell you about buried treasures.
From what I have seen in the Ivconic's negative ion detector thread and in this one, it appears that detecting charges in the air does not show you where treasures are buried.
The only exception is Esteban claims treasure can be found with the Zahori.
Yet everyone who built the zahori and other charge detectors say they find only charged things and power lines, but no treasure.

The other kinds of experimental locators we see are operating at VLF frequencies, similar to a radio.
These are not designed to collect charges from the air and display how much charge is collected.
A few people actually have shown some believable videos that these kinds of locators are doing something related to finding buried treasures.
If I were in your position, I would be thinking it will be good when Morgan comes to visit so you can see one of these in action and compare it to how you see your charge detector perform.
Hopefully you two will find some good relics in the places you know to go hunting.
Be sure to take a video camera so we can see what you find.

Meanwhile, I will see what I can do for your charge detector after we see the schematic.

This is my first time in the forum and it seems to me that you two are the most helpful of all in this forum.
I have a few questions that I would like to ask you. Can any one of you people provide me with any help? If you can my e-mail is: nikos0817@gmail.com
I would be very thankful to you if you help me.
A few things about myself: I am new in this field but I have some technical background since
I am an M.I.T graduate in a different field ( astrophysics ).

Hi haver,
It is hard for me to understand how you were able to graduate from MIT when you need to use a translator to understand English.
But it is even harder for me to understand why an MIT graduate would look for answers in the long range locators forum.

Can you give some information to help us understand how you were able to understand English well enough to graduate from MIT, and to tell the reason why you decided to come here to learn the answers that MIT Astrophysics department did not teach to you?

Hi WM6.Hello Friend, await your answer whether you made the device?

Which device? Did you mean zahori? No I never build zahori as electronic dowsing rod, but I build different static electricity sensor in past. No one for treasure hunting.

Zahori is electronic dowsing rod only. You need to be dowser to use it. I am not.

[nelson]

JUST TO SAY THAT WE MISS ESTEBAN, WHO IS I THINK, THE KING OF LRL.
I HOPE HE IS FINE AND BACK TO THE FORUM SOON

Zahori means the person with ability to find water with a rod.

Remember Carlos post only the schematic because three pages is heavy for the forum.

I repost in thread Confused on detecting noble metals at great distances...

http://thunting.com/geotech/forums/s...ghlight=ZAHORI

Read all the thread.

This schematic I have in Spanish, and always claim for the version in English. Maybe, nobody has here. This device was designed for to find water. In this German article (the original is the German magazine Elektor) assume that water in movement below the surface produce ionic interchanging. There are a Russian version about another title, a copy of original Elektor magazine of 1987 in the thread Remote Sensing Diagram:

http://thunting.com/geotech/forums/s...ghlight=ZAHORI

Original web page http://radiotech.by.ru/Shematic_PCB.../biolokator.htm
(doesn't work?)

Compare the both schematics, are the same! But the Russian has the title "Biolokator".

For to control a pronunciate arrives of ions, the 555 discharge the antenna. The article said that at major oscillation in 555, more sensitive is the device. The 15 nF cap is a kind of "memory", good quality requires here.

No synthetic clothes, no build in plastic.

At the end, the article saids that is possible to detect another type o field, include radiactivity (in theory).

I has done many modification for to convert simple and usable device.

Later modifications.
