Topic: Ferrite ring size

[Planokeith]

Hey Gang,
I was curious does it matter what size a ferrite ring you use to wrap the transducer cable around? Would a larger ring than what hummingbird sent me work since they say the more wraps the better ?
I was only able to get 5 wraps on my old transom transducer on my 959 DI with the ring hummingbird sent me . I installed my new XTM 9 WIDE DI 20 T. on my i pilot Which has a thicker cable ( Because of extra shielding ) and i don't think i will be able to even get 5 this time. I have improvement with my RFI noise with the new transducer but i have to adjust the unit in different depths of water. But it is still there.
Any way hopefully some one can answer
Thanks in advance

I don't know if a different size would matter unless it has something to do with the frequency it works at - which does make a difference.  This is why you should use the ferrites from Humminbird and not from somewhere else.

Okay Greg thanks

One more question maybe need to call HB , but do they just make one size ring? I watched a video of Doug V and he was able to get 7 wraps and there was no way i could have gotten seven. And now with the thicker cable i know there is no way.

Just the one ring size that I am aware of.  A thicker cable would take up more space which would mean fewer wraps do to the connector size not fitting through the smaller opening with the larger diameter cable.
