11 DD coil for fisher F2 and F4 fits all bounty hunter models.

I don't think coils are interchangeable between a B.H. Platinum and a Fisher F4…they are different frequencies.

One source of confusion is the terminology - "push on" vs. 'Screw in"

They all push in. One kind, that's it, you're done. The other kind, there is a metal locking collar that screws down on threads on the outside of the detector connector.

Calling them both "push-in" is what brings confusion to the table.

If it is female and has threads...it is a "screw-in" If it is male and does not have a screw on collar...it is "push-in"

Bounty Hunter discussions have called them that for years...no reason to change it now.
