Thread: two units on one transducer

What would I need to run two units off my trolling motor mounted transducer ? I have a Hummingbird 1199 SI and a Helix 10 SI .Will use one for maps mainly and other for SI and sonar . This will save button pushing while fishing unless I want to mark something . I will have a Helix Megs 12 SI linked to one off the ones in front also . The one on console for searching while at the big motor . .

Ethernet will allow your 2 front units to use 1 xducer ...

You will need the AS ETH 5XPG switch to connect all 3 units ...

And you will need the AS EC QDE to connect Ethernet to the head unit ...
