i think is a god metal detector
good luck

What kind of detector is this? It looks a lot like the hand drawn hybrid pulse

[ZOUjiarui]

The drawings look as crude as the Hybrid Pulse, there must be something wrong.

Many people use the term hybrid pulse, but do not understand what a hybrid actually is.. So I ask you, what do you mean by that?Explain the definition of hybrid pi!

Hi,
I had a look at the schematic.... OMG... this was a horrible attempt to "re-draw" the original published Pulstar I schematic. The Pulstar I (I think that is the correct name) was available as a DIY kit probably in the late 1980's to early 1990's in Germany. The price was about 129,- German Marks (approx. 65,- Euro).

Here the original drawing...

[GeoMax]

By the way this detector was not a Hyprid PI detector. This detector is more or less a simple one which samples only once like the PI Polones and Co... The Surf PI, MiniPulse, Barracuda or Hammerhead should perfom much better than this one.

[Orbit]

It's a fake scheme, it has nothing to do with the pulse star scheme.. I've known that scheme for a long time... As you said, nothing special.. And it has absolutely nothing to do with the hybrid pulse...Because of this fake scheme, many people were mistaken for many years that the pulse star 2 scheme exists on the Internet.

Hi Orbit,

check the spelling... I wrote "Pulstar I" and not "Pulse Star II". I know that this is a different detector and has nothing to do with the real Pulse Star detector you refer to. This schematic was also reprinted in the German Elektor book "Das Kompendium der Metalldetektoren" by Rolf Wilhelm from 2001.

See the book cover here....

Puls Star 1 ok.. It's important that you understand.. I don't write well in English..If you don't understand what I wrote I'm sorry.. I was looking for the definition of Hybrid Detector..

so will a schematic of PULSE STAR II to be show to public? HYBRID be cause there is a block of ID target, in my opinion.

dear friends this German pi one look like a fack because of ic LF357 is 8 pin not a 14pin.
i can't disgrace you but see even TL084 also is 8pin

TL084 it's 14 pin. TL084 is A1, A2, A3 and A4 IC. The LF357 is separate IC and should have 8 legs as shown in the diagram

[Sarkim]

Oh yes Bro you are right I didn't see datasheet TL084 is two package 8pin and 14pin
Thanks for your kind reply to me if you have pcb layout please share with me
Thanks.
