coil 180cm for golden mask deep hunter 3 se pro

[Op04]

I would like to have a device to measure the coil inductance. But I apologize to you, I do not have a device that does this, I only rely on resistance and experience (depth and stability).

It's ok, you have sharing good information already. Thanks! But perhaps someday if you can reach there are cheap inductance meter with included Q value which important for coils and you can build any size coil for your machine.

Thank you all. I have a question to complete this topic. I want to reverse engineer the device, but I am facing a problem, which is the presence of a strong black substance attached to the electronic parts on the board itself. How can I remove this substance without losing the device or damaging it? I will attach pictures of the article.

from your first story you must set the resistor in parallel to one turn, while on the sketch i see you show resistor in serial.
delete it anyway. connect turns directly.

I apologize for the error in the previous post, in this picture you will find the correct and sure information for the two files 125 cm and 180 cm, knowing that the final file is stable and has excellent depth
