Hello, i am interested in building my own DD coils for minelab PI detector, i understand that what you were doing was "nulling' the coil, i think you have to get it as close to zero, am i correct? could you please tell me what instrument do you use to do the nulling, i could see that you were using your phone, but is there some instrument that does the job, and could you tell me about the epoxy, is it really light when it is dry?
VLF is not easy to adjust but it is more powerfull and can get a smole coil (25mm ) at 25 - 30 cm on ground PI is easy to build but not so powerfull and can get 20 cm a coil with 25 mm of diameter.
@@n.e.c.o-en7717 usually a MD with pulse induction technology goes better in depth and mineralized ground like beach, look at Delta Pulse MD. Probably the coil needs to be bigger than 20cm on diameter and 5 volt power supply should be increased.
@@ivanbiasutti4567 in the Spirit PI the supply is 12 volts. The coil, yes i think you are right can be bigger. This metal detector is based on Russian Pirat MD it have 20 cm deep on 25 mm coin.
I like this channel. I looked at your web site also. I also have 4 assistants. 2 of which like to help me type. LOL
What resin did you use?

whats app for adjust the coil
الملف سوف يكون ثقيلا على الجهار ولم تضع عليه الاذنين الحمالتين هند ربطه بالقصبه
just how does this show you how to make a COIL? it shows you how to make a mold for the coils, and how to cast it
