Thread: Adding another Humminbird Helix to my boat and I have a couple of questions

I have a couple of questions and looking for advice on Humminbird Helix si/di graphs. I just picked up a helix 10 mega si grn 2 to go with my helix 10si grn 1. The mega will mount to the console with the other moving to the trolling motor. I would like to hear some input on connecting the two via Ethernet. All I want to share is map marks and nothing else really. If I’m correct a Ethernet adapter and cable is all I need to accomplish this hookup?
The second question is regarding adding a external gps puck to the unit on the console. I want to mount the external closer to the transom where the transducer is located for better precision. Is this a plug and play for the gps? Any advice or input would be appreciated. Thanks guys and gals.

Whatever you mark from the transducer will be off the distance between the puck and transducer if sharing the puck between 2 units because they both will have the same coordinate. On my setup the 898 and Helix are located at the console sharing an external puck close to transom transducer, the unit on the bow has a separate puck.
