Sometimes they do help and sometimes not.
With a lot of folks having RF interference on their electronics I’m wondering if putting a ferrite ring on the power cords to their units would help solve the problem. Just thinking.
I may be getting older but I refuse to grow up.

My Garmin come with one and was used.
You need to determine where you think the interference is coming from. a lot of times, ferrite rings are used on transducer cables close to the plug in end by the head unit of your electronics.
