Two Humminbird Helix 12's off one transducer?

[Z21 Tom]

Can you run two Humminbird Helix 12's off one transducer?
I thought there might be a splitter cable?
Any help is appreciated.

No, not with a splitter cable. Yes via Ethernet.

I see you have a 360 and two displays now. If you have all three connected via Ethernet, you can do it now.
Just turn Sonar OFF with one of the units---same as disconnecting the transducer. Then chose the unit with the active transducer as the source for sonar data in the unit's Network menu.
That is what you would do when adding another unit and not connecting its transducer.

The unit generations would determine IF and how you can share sonar data.

Wayne, I have a Helix 12 Mega SI G2N at the helm and want to add another Helix 12 G2N at the helm and want to know if I can share the transducer thru the Ethernet port? Sounds like I can if I shut the Sonar OFF on one?
The two Helix units at the bow with the 360 are first generation humminbirds.
Thanks Wayne these are my first humminbirds so I'm learning lol.

Don't install or connect a transducer to the added unit. Just turn Sonar OFF and share data from the other console unit.
Are you familiar with the Network menu?

To share sonar data between a CHIRP unit and non-CHIRP unit, you have to turn CHIRP off.

Thanks Wayne I will give it a try.
