    FERRITE COIL FILTERS do they work

    I have seen these on ebay and wondering has anyone used any of these on their metal detectors.

    States that it would be a low cost way to reduce EMI & RFI electronic interference noise into your metal detector from external elements.
    I states it allows you run higher gain/sensitivity on most detectors..?? while reducing noise or chatter associated with running high gain settings.

    Is this true?

    Possibility! If you're having interference problems, try spraying your coil with a little "Static Guard". Yeah, sounds kinda corny but was having issues with an older detector swinging through a field of dry grass that had been cut. Someone suggested it was static from the grass. Said what the heck tried it & it appeared to work on two different machines. Like I said, it sounds corney but they can't shoot you for trying. Another tip, if you have a skid cover on your coil, pull it off clean inside with a damp rag. Put the cover back on and seal the crack with a tidy little bead of silicone sealant. Guess that powdery dust can interfere or pick up a charge. Let us know if it helps!

    I know it's here, just need a bigger coil!

    I think I know what my last words will be....

    If they are worthless, why does Minelab use them on all of their CTX3030 coils?

    Why add cost or un-needed parts to the coils?

    Here is the thing. Ferrite cores are effective for certain frequencies. If you dont get the right one, it won't work. I was just recently looking into something like this and I needed more experimentation.
