Good Afternoon Tom,

I have another question in relation to trying to minimise interference (if electrical). I looked through the use of RF / EMI snap on chokes in the search section of the forum. I have a question from what i have read to date. If you have to put up to 6 chokes on some power sources, do you know what "material" the choke has to be??? the more i look in to these chokes the more types there seems to be. I was going to source some through RS Online. They have a lot of electronic supplies at very good prices. But looking that their selections they have different materials for different frequencies? Do you have any idea of the material that the power lead chokes are on the Ray units? From what i have seen thus far, there are Type 31, 43, 44, 61, 75 material (Fair-Rite Brand) that all do different things. I don't have a clue as to which one is best to use for taking out potential electrical noise from my system.

If you have any pointers that would be greatly appreciated. If i could simply move all my wiring for the MFD and transducer cables to the port side of my boat i'd do it. But i'm not real keen on trying to get under the floor of my Caribbean.

Are there any general rules for how much distance between transducer cables and power cables is acceptable? The opposite side of the boat is great in theory but not in practice. I can probably get about 100mm separation where they run under the side pockets of my boat. That's why i'm thinking of seeing if simple clip on chokes could help minimise any noise that could be in the engine wiring harness, or power supply leads that runs to the dash with the transducer cables.

I might be clutching at straws by hoping some simple chokes on some power cables will help but it will be cheaper and far easier than other options going through my head at present.

thanks again
Ryan
