felezjoo PI(the best pulse induction metal detector that I made until now)

[pigeon]

Hi Michael
Thank you vert much

[mohandes]

Hi everybody. I see some people are in doubt about this MD abilities.
Be sure it really worthies to be made. I’m one of the first ones who made it.
It is very stable and powerful.
It can detect with an appropriate 23 Cm coil up to 120 Cm. and with 1m x 1m coil 4 meters or more.
Mr. Hamid is really a genius it’s my honor that he is my compatriot who presented this MD free of any charge to his compatriots for solving one of their most important problems.
Wish Best things for you.

where are you from?

Video test for felezjoo metal detector ?

would you please, erase our doubt by showing some clear videos not by doubtful phrases and claims?
coming here and claim without any documents, is not good for your honor.
show us test videos done by yourself.
especially iron rejection option.

Made some tests today with regular wound coil (PVC insulated cable, multi strand, 0.8mm) - 38cm diameter and it doesn't seem that sensitive (no more than 1 meter sensitivity).
I'm going to try 1x1 coil to see how it performs hope it does better than that.

Have you had a chance to test the claim of iron rejection? If so, can you tell us how it performs?
Thanks in advance.

> PVC insulated cable


coil = amplified EM-field !

This can't work if already the gaps between the wires itself are 0,2 - 0,4 mm .
I see this problem with alot P.I. detectors:

Some think a few loops of lose wires will do the job and
a few loops for some 1m coil have to guarantee a good depth... Shurely not.

If this detector really wants to be that good as claimed it needs some professional coil first.
Perhaps something like 0,3mm enamailed copper wire with at least 20 windings for low power P.I. -
glued or bound very tight together.

To have enamelled wire you need to wind a basket coil, otherwise you get high capacity coil, not good for small targets. The first coil i have tested is not perfect indeed, i have done some calculations for 0.7x0.7 square coil as i have some spare cable with exact specs. Ultimately basket coil needs to be used no matter what type of wire is used enamelled, PVC or PTFE.

here is another test video of felezjoo pi found over the net. just valid for 7 days. mpg format

Well ... that was a good example of random beeping.
I can honestly say that I've no idea what was being demonstrated in that video. Firstly, it appears to be reacting a hot rock, and then something resembling a hat is passed over the coil, and the beeps are all over the place.

The second item passed over the coil looks like some kind of metal air filter. Made out of iron.

correct. exactly metal air filter belongs to bus or farm machine.
couldn't translate it correctly but the person who done this test wrote somewhere that " it detects clay or hot rock and by increasing rejection ratio, device can ignore rusty iron, also hot rock"
seems at first device beeps and at the end of video by increasing rejection ratio, device ignores presence of rusty iron.
but, sadly, until now through 1300 pages on their forum,couldn't find any proper video or something at least clear subject a little bit.

Can’t you see what I wrote? Hamid Compatriot. It means IRAN. Can't you do anything except to laughing?

It’s somehow difficult to prepare video. Main reason is our situations here that we mostly have to use devices at night, another reason is problems for uploading big files of movies, but if I get any appropriate time will surely do it.
BTW; about iron rejection; don’t take it very serious. It can do it more or less and mostly with small size of coils. I mentioned its’ ability for metal detecting in all metal operation not discrimination or iron rejection. You can assume that want to build a simple powerful metal detector without any discrimination. doesn’t it worth?!!!!

hummmm!!!!!!!!
let me check your answer

1- i asked you few test videos but not at night at nature.
you can record a few seconds video at home at your room but clear and professionally.
2- you can compress or change your videos format and upload on several free sharing centers as many others did.less than 10 megaB.
3-your compatriot or friend "Hamid", who has designed felezjoo, highly emphasis on FE-rejection option.so we expect and ask evidences.we all have this right.
4-yes. i agree that it is simple digital pi detector with some useful options but how powerful it is?
how powerful? again here we need your test.

hope to see your tests and success.

hello ossman22

thx for presenting video, i think it is good enough to build

would you please be so kindly to load the project datas here on this thread
pcb files, programm code shematic

best regards to you
