OK bear with me…hope I can explain what I want to do so you understand me.


I want to replace my 788CI HD DI up front with a 999ci HD SI.
A lot of the lakes I fish have hp restrictions on them, so I’m using my trolling motor to get around. I want to add side imaging/down imaging up front. Have an 898c SI at the console for the non hp restricted lakes.

So my questions are …..
1. Do any of you run a side imaging transducer off the trolling motor?
Pros and cons?
2. Can I use the existing 898 transducer on the back of the boat for side imaging on the 999 unit? Looks like they use the same transducers. Think I’d have to install a US3 switch allowing me to switch between the 898 and the 999 units?
3. But then what do I do for down imaging/depth up front? If I use the standard 999 transducer on the trolling motor for just depth/down imaging what would I need to switch from the back transducer to the trolling motor transducer, another switch the TS3 or is there a coax splitter that will do all of this?
Hope this makes sense …and there is an easy solution
