Creating a coil (Tesoro Cibola)

[sled]

Hello,

I want to create my own double D or double O coil for my Tesoro Cibola detector. Is this possible? Because I'm a newbie in this area, but I want to figure out how this works

What do I need to know for building a coil for my Tesoro Cibola? Connection plug arrangement? Resistance?

And could a "wrong" constructed coil damage my detector? I could use an oscilloscope and induction measurement device at school.

Perhaps someone has already built a coil for a Tesoro Cibola or similar.

Please help me

Thank you very much

best regards

Simon
