Humminbird power cord

[Fish'n Lewi]

I have a 597ci hd di and was wondering what the circle part was on the power cord.



Thanks!

Without tearing it apart, probably what's known as a choke for noise reduction. Usually an iron ring with a couple of loops of the power wires through it.

I agree with GA Boater. They are called ferrite coils and help eliminate interference (or noise) on your electronics. Especially a depth finder.

That's the name I couldn't remember when I posted.

They're primary purpose is to suppress the noise coming from your electronics. Fish finders are very noisy devices and the cables act like an antenna for the signals they carry. A ferrite "chokes" the RFI transmission which is why you find the beads at the ends of the cables closet to the unit.
