Okay, I am currently running a HDS5x off the stern of the jon boat (came with the boat).

I want to put this unit on the trolling motor, and add a HDS7 Gen2 for the stern. I want side imaging and down imaging capability, GPS mapping, and waypoint storage. Anything else I need to consider?

I have a Minnkota with iPilot on the bow if that matters?

Their is some other neat technology out there such as the Humminbird 360, iPilot Link, etc .... but I don't think I'm ready to go there just yet.
