Which Coil is Best

[sharky]

Which coil is best for PI, coplanar wound side by side, dual (windings lumped together) or mono or dual coil wound side by side....

[Carl-NC]

Depends on the design of the PI, and how you are using it. I suppose a truly balanced dual coil will offer the fastest potential sample time, if that's the goal. But it might not offer any advantages over a well-designed fast mono coil.
