Topic: 898SI and 858 DI Transducer questions

[jgcox6]

I have a 898si i have a on my console and a 858 DI on my bow...i have an ethernet connection between the two.  My questions are concerning the selections for the transducers.

1. I am confused on what to set my transducer settings..on the 898SI I think it needs to be the 200/83khz selection for the 2D, and 455khz for the SI?

2. Should I set my 858DI transducer settings to 200/83khz for 2D and 455khz for the DI (to get more coverage area?

If anyone can give me some pointers for those settings...and how that should be set up in the ethernet menus....would be great.
