For PCB and how to build see ETI561 article again (and again).

For 30 cm coil you need to wind 46 turns.

You ETI561!!!

I wonder if someone already friends rode ETI561 this detector and how it sencibilidade.
Thank you very much...

ETI561 is the best BFO detector.

ETI561 is the best BFO detector.

And the best in terms of that sensitivity??
Say that his sensitivity to detect a small metal plate of 2cm x 2cm??

Thank you very much yhl

ETI561谁建立。灵敏度可以吗？

ETI561 who is in the building. Sensitivity can it?

thanks for good information friend

thanks for good information friend

luciano Furtado do not be mad at yhl he is a bit "strange". My advice is to do CCO metal detector:http://www.geotech1.com/forums/showthread.php?t=16777
