Fish finder placement

[SGibbs29]

I have a Helix 7, 798si , so it had a few miles on it, but in good condition. I have brand new helix 9 mega si g3n gps. Which one would you recommend for the console and for the trolling motor?

since I do most of my fishing from the bow of the boat I have my best unit up front.

JMO but I do most of my searching with side imaging at the console, so I'd want the bigger unit there.

Once I am on a spot and fishing, the only thing I need on a bow unit is 2d sonar to see what's going on.
