"orange" is coil wire (Cul windings) presented in cross section.
Yes, with longer ferrite you can get more directivity which in results is same as more sensitivity.

tank you very much dear wm6
The new metal detector will be revealed during in the soil?
If the new metals in the soil can not hide the obvious?
Tell me how to test the circuit?please
waiting for yoy
whith respect
