Linking 3 Units

Need some help. I have a 858 on my console tied to a 788 on the bow with Interlink. The 788 used the transducer built into the trolling motor, the 858 has a glassed in transducer.

I would like to add a 788 in the stern to use when back trolling. I believe I can get a switch box to used the same transducer as the 858, but how do I share the same GPS? Do I need a second Interlink box?

Thanks!

Hi,

Here is a link to the “Interlink Controller” pdf. The network you are proposing (if I understand what you’re saying) does not look like any of the possible connection scenarios that I see illustrated … you decide.
