I recently mounted a Helix 10 SI on both my console and my bow. Both units are Ethernet together. I-pilot only, no link. I am contemplating mounting another Helix, possibly a 7 Sonar/GPS on the console and Ethernet that with the other ones. Obviously I need a box and all the necessary adapters/mounts. The reason for this is if I see something on the Side Imaging unit, I can mark a way point, and see it on the 7 without having to jump screens on the 10, or I could have a smaller GPS screen on the 10 with SI screen. Is my thinking rational on 2 units, or should I just stick with the 10 and settle for the Hot Keys in jumping from screen to screen? I would also have to jump my Lakemaster and my Navionics card from the 10 to the 7 and vice versa depending on where I am fishing that time. I do go to Canada often.
What are your guys thoughts on this? I am looking at around $800 to do this set up.
Any thoughts or other ideas would be greatly appreciated!
