NEXUS circuit diagram

Hi to all

My search for NEXUS circuit not any result yet.

Can any body upload here or send it to my email ?

Thanks .

[schatzsucher]

I´m very interest for schematic´s too

[Gosho]

I can provide the full (fully tested) information for the interested (payable) of you.

Do not believe anyone who claims that they have Nexus schematics. They lie.
There is many similar (some of them were posted by me) to the Nexus schematics, but the original Nexus schematic was not posted or published anywhere so far.

Arado 120b

I think the nexus is a copy 120B with a few added bits,it seems very simlar,I am not saying it is exactley the same,But i do think the idea was copied at some time,Norman.

Hi,
I don't know for sure...can guess... but I think not.
Isn't Arado120b a BFO ?

From what I know (or think to know) Nexus is just an older schematic redesigned from other previous bulgarian works and thus provided of newer circuitry like some you can find in e.g. Tesoro's or White's. Think e.g. at sampling, timing, low noise op amps etc

Then the "secret", as Georgi said here before... is not in the circuit, but in the good coils he made.

A power osc + a very good OO coil and voilla: you get your targets deeper.

For me it's a good explaination and I trust him... have no reason of thinking there is an Arado under the cover.

Kind regards,
Max

Hey Georgi, I used a Nexus at Mike Longfields a couple of weeks back, and I have to say two things about it..

1) It's the best damn machine I've EVER used.

2) I didn't find it that hard to use, but whilst definately NOT a beginners machine, I found it very intuitive and stable.

I told Mike I was impressed (it was HIS machine I used) so he suggested I might like to post my opinion of this machine on a few forums, so, for what it's worth I give it a 9.8/10

I for one would like to see this machine more in the mainstream and public eye, detectorists need ot know there is an alternative to the Lamebins and Hounty Bunters and PX's of this world, in fact ANYTHING sold by the large dealers.

I wish you luck with your new venture regarding the Nexus line of machines!!

Hi,
"1) It's the best damn machine I've EVER used."

You tested it with the big/standard OO coil, right ?

Many reported that... and I'm sure it's so for many people here, but... take a look at GoldenSabre thread... me and others think that a TGS-clone with a 25.5cm DD could pass the cache-test (220 silver coins at 24'' depth) easy...

So far no MD passed the test... but Georgi claimed (reported by Qiaozhi) his machine can do (and why not)...but...maybe it's worth you build one TGS to compare with your Nexus experiences what's better!

About stability...what about motion/non-motion... is there non-motion search-mode on Nexus ?

Best regards,
Max

I have a Bandido, and it could not possibly pass the cache test.
Anyway, why don't you ask Carl? He most likely has a Tesoro in his collection.
TGS is an older Tesoro design, but they all have similar performance. Also you need to remember that the detector must be in discriminate mode when performing the test.

In answer to your second question - none of the Nexus detectors have a non-motion mode. On the Tesoro it is used for pinpointing, but in practice I don't find this a very useful feature.

Testing with original TGS setup will not help much. I guess it will not pass test with original Tesoro coil at all. But....! Handmade TGSL with handmade DD coil (27-32cm) MUST pass mentioned test. I strongly beleive in that due my fresh experiences with my TGSL. It is noticeable also on other original metal detectors. I have seen handmade Classic III works much better than original...Also original Fisher 1266 works much better with handmade coil.....Too many cases on this making sort of rule. To tell you the truth i havent seen yet handmade Minelab to work better than original.....come to think i never saw any of Minelab Handmades at all!


About non-motion mode.....i think you are wrong. Non-motion mode offers much more facilities than motion mode. Main difference is motion mode lack due fixed(preseted) GEB...in most cases huge loss...on most of terrains.
I dont need to repeat what George Payne already explained...But it is truth..
Despite so many lacks, despite it is obsolete; yet Cscope 1220B showed to me as very good and usefull....even much better in real conditions than many newer, more modern detectors....Main thing was fact it is non-motion detector, so i can adjust GEB,SENS,DISC....any time when working conditions were changed....

I will perform test (220 coins in jar at 60 cm) these days and honestly post results here...
Regards!

I quite believe that this is true. The original Tesoro coils are tuned off resonance, but when you make a homemade coil it's possible to tuned them closer to the resonance point and hence improve sensitivity. Of course you may have some problems with the GEB and DISC circuitry, because of the different phase relationship between the TX and RX coils, but some simple circuit mods can fix this. There could also be some instability issues.

I think you misunderstood my comment on the non-motion mode in the Tesoro. There are many plus points in favour of non-motion, as well as some minuses (GEB problems, for example). My reference was to the use of this mode for pinpointing.

I look forward to the results of your test.

Oh, yes! Does make sence...
