ANKER SS-60

Carlos, you are so good... thnks.
I hardly demand you do a site research http://anker50.narod.ru/a_ss60.htm
and see anything. a sensitivity is 60 sm on coin diameter 2,5 sm (5 USSR' kopeek). it is NOT PI detector!

Carlos, este es el PI del que me hablaste y que te da buenos resultados?

Carlos, is this the PI you told me who present good results?

Si Esteban, puedes poner las fotos que te mande

Yes Esteban, can you put my photographies of this metal pi detector ?

En este circuito yo reemplace el detector de baja tension por un detector basado en el TL431 mas simple para regular el punto de deteccion de baja tension con un preset

In this circuit I replace the detector of low tension by a detector based on the TL431 but simple to regulate the point of detection of low tension with preset

Acá las 2 fotos que me enviaste.

Here the 2 photos you sent me.

Hi Estwban. I constructed this detector but the results are not so good as it write. I had a negative output and maybe this was the problem of medium sensitivity. I used a plastic 709 so maybe to had parasitic oscilates (the gain is very high).

Hi KT315. Do you know where i can find schematic of pcb for anker 50 or 60? Is there KIT for this project or where i can find the Russian IC's and coil?
Is the coil of Anker50 the same with anker60?
Regards

[Esteban]

Carlos built many PI detectors, include walkthrough PI detectors. Of course, he modificate and adjust parameters in this PI from Poland for to run OK.

Wow!!!


...." sensitivity is 60 sm on coin diameter 2,5 sm ..."

KT315 are you sure !!!??? It should be the very best result i ever heard so far!!!!!! Even much bette than Minelab!!!????
Is that so than i do congratulate very much...


One more thing.....in the air or in tha ground?

hi, geo. a site in russian but I think it will clear for you. click on top [SERIJA ANKER] http://anker50.narod.ru/
and you will go on the info.
there are not rare IC's you are not able to get of. the coil is similar because schematics' similarity. about KIT try email an author, I am not in course of this.
have a nice day

> One more thing.....in the air or in tha ground?

testing in air. Anker has sold the detector without detail testing at ground. SS-60 is slightly advanced version of his A-50 (M), full bridge TX stage for example etc.

Hola todos y Geo, el circuito de EP08/2000 no tiene el regulador de tension positivo y negativo como tienen los otros circuitos, el que envio del sitio polaco es igual al Sandbanks y al Proscan salvo el ultimo P Fet que actua como resistencia variable en el oscilador de audio. yo creo que todos lo pi trabajan exactamente igual, con un osciloscopio y un poco de criterio se logran resultados mas que satisfactorios dependiendo de algunos componentes para hacer al circuito mas inestable (sensible) uno que otro

Hello all and Geo, the circuit of EP 08/2000 does not have the positive and negative voltage regulator as they have the other circuits, the one that shipment of the Polish site is equal to Sandbanks and they Proscan except for the P Fet like variable resistor in the oscillator of audio. I believe that all pi works exactly equal, with an oscilloscope and a little criterion are obtained satisfactory results but that depending of some components for does to the circuit but unstable (sensibility) one that another one

Hi Carlos. I agree but it is the same because there is symmetrical voltage 0..+6..+12 v.

I agree. I want to supplement that beyond the change of elements for more constant operation or for increase of sensitivity, exist individuals that change certain elements of circuit only and only in order to present the manufacture as their trial study and inspiration.

Hola todos y Geo es verdad que tienen tensiones simetricas +/- pero no reguladas ya que cuando varia la tension de la bateria con el uso, cambian lo parametros del IC mas importante que es el ua709 o el lm318 en otros circuitos y hay que tener en cuanta que si se quiere estabilidad en la prospeccion, hay que tener en cuenta estos reguladores (7810 / 7905), por eso es tan importante tener un detector de bateria baja

Carlos

Hello all and Geo is truth that has symmetrical tensions +/- but not regulated since when varies the tension of the battery with the use, they change the parameters of the important IC but that he is ua709 or lm318 in other circuits and is necessary to have in which if stability in the prospection is wanted, is necessary to consider these regulators (7810/7905), for that reason it is so important to have a detector of low battery
