Nexus Coil Design

Here you found a britsch VLF IB/TR Detektor with cool Coil Design and very deep founds:

Can anyone tell more about this coil design ?

[Gosho]

The Nexus idea comes from my country. It was very popular some years ago.
It uses 2 identical coils, each 20sm. The interesting thing is that you can't get it working if you squeeze them to a 2D standart coil. I can call this coil 2O
See one small part of the circuit attached

Have you more of the nexus schematic ?

Nexus Schematic

Any chance of seeing the whole schematic?
I'm interested in discovering whether there is anything novel about the electronics, or is the extreme sensitivity simply due to the coil?

It is not british. It works good only in soil-less ground. There are 3 modifications. I think the part i posted here is the best of them. I cannot post it full, because I've given a promise to keep industrial secret.
I can share coil information - the coil consists of 4 windings: 2x30turns,and 100/130 turns for Tx/Tr. I works at 10kHz.

Hi Gosho,

OK - understood. But why post only the modified part of the design? If we cannot have the whole schematic, then the glimpse you have provided makes no sense to anyone who does not have access to the whole design.

What do you mean by "soil-less ground"? According the pictures in the link there seemed to be plenty of soil to me.

[Gosho]

I've posted some coil information, please read it.

[Qiaozhi]

Where?

I've posted some coil information, please read it.

Where have you posted it?

Abouth part of picture from "Nexus"

That can't be part from "Nexus" coil !!! That is a part from synchronic detector.Before time I calculate that shematic but for other aplication.Somethimes,some peoples take other men for stupid child.
To ALL:Before do anything,test shematic!!!

[quink]

..but the schematic http://img419.imageshack.us/my.php?image=part26oz.jpg is not complete. post the other parts too, please

[Bojidar]

I will try to find shematic of "NEXUS" and coil info,but that is a hard work. Before years I saw it,but then I find some mistakes on it.Original synchronic detectors was build on ferrite cores.Oscilator was very interested-I try to build it and a voltage across coil was more than 140V p-p pure sine wave,and all op. amp was 741 and TL081.Remember only that,because was long ago.

Nexus

Hi there. I am a the Nexus designer.
Now guys it will be more constructive to stop talking nonsence.
Non of you can provide the Nexus schematic since was not posted anywhere to anyone, ever. It does not exist in any computer either, so it can not be hacked out.
The so called Gosho I guess is from BG and you Bogidar also.
My name is Georgi Chaushev. I am from Russe, BG.

The general information about the Nexus is this;

It is based on the same principal as most of the BG detectors, but it does not usilise ferrites or feedback balancing circuits.
The coils are fibbre glass and ABS frame and are a little more advanced than the traditionaly dipped in resin coils.
And also what Gosho says the Nexus works only on soil-less ground is BULL****.
He does not have any idea what he is talking about. Typical for some arrogant individuals from BG.
As a matter of fact the Nexus is the only existing in the world detector capable to find Roman sesterci at 40 cm. (almost 16") depth for real with very accurate discrimination.

If you are really interested in what the Nexus is I am ready to provide you all of the accurate information and in the future if possible a demonstration. I can give away schematics as well but they will do little good, because the secrets of acheiving great depth are not in the electronic part of the Nexus.

All best.

Hi there. I am Georgi Chaushev the Nexus designer.
The scematic shown on the link is a froud. It has no relation to the real Nexus offered on the market.
For more detailed information please contact me at [email protected] or 01442219803 at any convinient for you time.

The guys from BG will not be able to tell you anything as real fact even their claims of experise and information access.

Hi Georgi,

What do you mean by BG detectors? Is this a type of detector, or does BG mean Bulgaria?

I guess you're saying that the secret is in the coil ??

By the way, I'm not interested in hacking the Nexus schematic. Just curious to understand how you have achieved such astounding performance.
