What Is This Black Box Attached To A Coil Wire.

Big Foot Coil Wire With This On It
 
If you open it up you might find one of these ........... ferrite filter. Some thinks it helps to keep EMI out of the detector, but there is usually an EMI filter on the input circuit anyway. It might be an impedance matching transformer too for the older Bigfoot. What model does that coil fit on?

Thank You.
 
It's NOT a Ferrite filter. There is a jumper in there. It kind of shaped like an auto fuse with 2 legs. These early bigfoot coils could be used with the early 6b detectors or the new (at the time) 6.59 kHz frequency machines. You turned the jumper by pulling it out, turning it 90 degrees and re-inserting it depending on what detector you had. That BigFoot dates to about 1990.
 
Thanks for the info Tom, it is hard to believe that the Bigfoot has been around for that long. I don't remember that version at all.
 
Next obvious question would be which way does that jumper go for which detectors???

Thanks,
 
It's been too long to remember. It doesn't hurt anything if you get it wrong. One way will work and the other won't
