Gary pulse 1 circuit, the actual test data.

[yhl]

Gary pulse 1 circuit, the actual test data. Detection of aluminum coins to 20 cm. Detection of iron coins to 20 cm . Sensitive to the nails. The actual detection of underground objects, full of nails. Not a good detector.
Who some advice?

[yhl]

This detector is very sensitive to the iron.

This detector is very sensitive to the iron.

ohh... my buddy... I congratulate you because you have found America continent.
Discovery Number 1 - PI is not so sensitive to the gold as somebody is wishing.

great... you are on the right way, my friend!

Thank you,

Thank you, may need to find another place.
No garbage, looking for gold

yhl you asked: "Need one. Farmer with a metal detector. Recycling old metal. Metal detector circuit." http://www.geotech1.com/forums/showthread.php?t=16784 . PI detectors are ideal for this. And now you've changed your mind you want coins and gold,silver... Where there is a lot of nails and other waste is the best a VLF detector. Because of possessing good discrimination.

[yhl]

yes

Yes MAIKL, I would like to find gold coins, gold, because the PI does not distinguish between non-ferrous metals. Detector barking. I have a simple circuit, you see, is not it better than GARY PI 1?

[maikl]

There is no simple and well at the same time.In this forum you have lots of good schemes and exchange of experiences around the building. There is little effort into "translation" and go forward.

LOL! Like I can Read that!

YHL, It s time for you to go out and BUY a GOOD VLF Detector with a Digital Display and Proper Metal Descrimination.

Something in the $3,000 to $6,000 Range, Might help you get you the Treasures your looking for.

It is VERY UNLIKEY the Circuits your trying to build yourself, will Never do what you want.

hello

English inside the PDF, this is the EPE bounty hunter circuit. This circuit is OK?

It is OK for Some People, But I Doubt it will suit you.

circuit is OK. but very poor. thinking in your head still all are not so OK. you are beginner and seems all usefull info goes in your head through hands. why you do not wish to learn? why, buddy? go to hight school, increase your electronic level at hight, learn these electronics, read all books and magazines you can find and be back again in forum. if you will not be grow yourself you will only ask idiot questions. leave this schematic. do Qiaozhi Fisher 1210 clone. I hope Qiaozhi will agree to sell one PCB to you.

Thank you, I already know. The original need depth. Now need to be useful.
