anyone tried a clip on ferrite filter

Really I wouldn't think these really do much at all but for $4 if they did anything more then nothing I would grab a couple just for the heck of it. I've heard a lot of people say they don't do anything at all and some people say when they tested it out it didn't help much but did do a little. Anyone have hands on experience if so what did they do. Like I said not looking for a big change just curious if they do absolutely nothing or negative effect.

There was a thread about this a month or 2 ago. A guy was getting interference from power lines (I think).
Search around, I think it did help him. Here a couple I found

Have you actually used and tried one or just going by what you've seen

Yes, we tried them on our Minelab GPX machines, friends tried them on their VLF's - complete waste of money and time.
