Hello all, and thanks for the use of the board. I recently picked up 3 older Fisher Coils at a local sale. They measure 5"w x 10"h for the larger ones and 3.25"w x 6.5"h for the smaller ones. Can any of you Fisher pros out there help me identify which detectors these will work with? Any help with a ballpark value? Thanks so much for any help you can give.
