GOLD GUN AL707

[ionios]

I just finish it, so i am going to test it now
and i will give you the resoltes,
with out transmitter,
Thank you.

Hi ionios

I hope your GG works, so i will look forward for your results.
For J.PLayer, my friedn i was tryiong to understand this divice function and i compared to pdk, wich is also a VLF receiber.
About GG, i think that is not necesari to have the correct ferrite to catch the correct frequencies, cause you can use other ferrites to or may be the same arrange has pdk RX coil. The point is to set the correct frequency by just doing a correct LC circuit tune to the frequencies you want to recibe.
May be by just building a small vlf transmiter, like coil stimulator made bu pdk, will do the job to.
In ather words i think that you can combine pdk and GG schematics to get a good LR MD.

Nelson

Yes, Nelson, the main point is correct frequency. Mean frequency tuned to transmitter that can be received in your local.

There is a little use, even if you have original GG, if there is no TX frequency on which GG is tuned in your local.

You can replace non-existent (military) local VLF signal transmitter by your own portable one. I have already posted some adequate TX schematic here.

J_P can explain this matter more in detail.

Hello friends, here is a small video,

http://www.youtube.com/watch?v=m8O4Vm6iivw

It is the first time i use the gold gun so i like to ask,
If someone use gold gun from you,
What you think about the video and the numbers i get in organe?
Is it works like must be?
Thank you.

Congratulations ionios, very nice construction.

Yes, I tested GG circuit in past. With proper tuned antenna it can easy detect direction and position of small transmitter, but i never can detect reliable reflection from metal targets. Transmitter signal always override reflected signal and disturbed receiving of weak reflected signal. We need EM shielded antenna. I left this project without a valid success.

[ionios]

For the video I didn't use any transmitter,
So you think it is working correct?
The next days I am going to check the direction
That gold gun so me,
I will be very happy if I found any metal there.
I let you know about this.
Thank you.

Congratulations ionios
Very nice GG and in the video if i m not wrong you got a null signal. Tell us how and from were you got the transmitter signal.

Thanks WM6
I will try to find the transmiter scjhematics you posted.
I m not shure, but is my idea that mixing GG with pdk device could allow me to have succes on long range MD.

How did you made GG digital. Do you have schematics to share?

Here it is the circuit for the gold gun i make,



And the change i made with the capacitors connection

The gold gun is a radio receiver similar to a small battery power AM radio receiver.
The gold gun is tuned to one frequency to listen to a radio station.
The design shows a switch which allows you to tune to 3 different radio stations.
The gold gun does not find any signal from buried metals.
The gold gun finds a signal only from a radio station that sends a broadcast at the same frequency that the gold gun is tuned to.
If there is no station sending a radio broadcast to the gold gun, then the gold gun will receive no signal.

Today, the radio transmitters which send signals for the gold gun are not working.
There is no transmitter sending a signal to the gold gun, so the gold gun will receive no signal.
It will only show occasional variations of random noise.

If you want the gold gun to work, you must build a small transmitter that is tuned to the same frequency as the gold gun.
Then your gold gun can receive the signal from the transmitter.
The transmitter does not need strong power.
50 milliwatts is much more than you need.
This transmitter should have a loop antenna to send out the VLF broadcast.
A loop antenna will send a 10mw VLF signal maybe several Km distance for easy reception of the signal on the gold gun.
When you have your transmitter tuned to the exact same frequency as your gold gun, then you can put the transmitter to the side of the place where you want to hunt for buried metal.

When you see that you are receiving a carrier wave from the transmitter, then you can use the gold gun to search for buried metal.
You walk in the field and watch for when the carrier signal goes to a minimum.
Then you move some meters to the side and search a second time to see where you find the minimum signal.
The place where the two lines of minimum signal cross is where the buried metal is located.

If there is no transmitter in the distance sending a signal for your gold gun to receive, then you will receive no signal to show where is the buried metal.
The buried metal does not send out a VLF signal that the gold gun can receive.
Only a separate transmitter can send a signal for the gold gun to receive.
The detection of buried metal is done through the principle of induction due to the metal properties of the buried metal.
The buried metal can make an inductive anomaly of the signal that you receive from the transmitter.

Remember, most people say the gold gun does not work.

"...I could not get the gold gun I had to work. But that may be because the signal was not being transmitted. This unit has a transmitter.
I can't say if it will work or not. I just wanted to let everyone know there was one on ebay".

Thank you for your answers, I didnt use te same frequencies that the gold gun use,
I make the board a little bigger and i use 12 position button, with 12 different values
capacitors for the coil,
Also one extra trimming capacitor parallel with the coil to adjust the the small frequencies.
I hope the resoltes are good.

Your gold gun will not receive any signal unless there is a transmitter sending a broadcast at the same frequency that you are tuned to.

The exact frequency does not matter.
But it is important that the gold gun is tuned to the frequency of a transmitter, or it will receive no signal.

For detection in deeper ground, lower frequencies are used... 10KHz - 15 KHz.
For detection closer to the surface higher frequencies are used... 25-50KHz
50 Khz is good for penetrating the ground 2-3 meters or more depending on the ground.

You can use an adjustable signal generator to transmit a signal.
If your signal generator does not produce enough power, you can add a single amplifier stage to power a loop antenna.
Then adjust the transmitter frequency until you receive a carrier wave on the gold gun.

Ionios you receive the signal from Germany for clocks ( time signal ), or the ionosferic noise at 20KHz that all the people forget, or something else ...
You are lucky, because 300km East from you, we don t receive the first one. The second is not stable.
