Does anyone have experience with one of these.
I read an article stating to place one of these on your sonar wire so it can reduce the clutter/rf signal Which comes from the battery or trolling motor. This supressor is suppose to reduce rf noise in the screen. Attachment 196635
You can get those clip on models at Radio Shack. I've tried them but they don't work really well. Helps, but not a solution.
Cool thanks.Quote:

Would it be better to place one on the cranking batter cable since that's were the interface is coming from.
I've never heard of anyone putting one on the battery cables.
The ferrite core does not eliminate EFI/RFI ...its job is to arrest EFI/RFI before it reaches the head unit ...
If the ferrite core is put anywhere in the cable except right before the head unit ... Other stray EFI/RFI can get in the cable between the ferrite core and the head unit and show in the unit display as interference ...
Install the ferrite core as close to the head unit as possible ...

If you own HB products ... They will send you ferrite cores designed for the specific frequencies of their own xducers ...Quote:

And today I learned something new!Quote:

I've asked ... Because I wanted to learn more about ferrite cores and eventually make that discussion a Sonar Quiz ...
They will only tell me this ...:

Worked well on my HB

Good. Some people know more the I do. I user an o'scope to see if the cores have any effect. If not, I change Mu.
