Hey, I am new to this site and I am looking to purchase my first gps down and side imaging units. I am hung in what to purchase, I was sure I wanted a Humminbird 898 for the console and a 700 series for the trolling motor unit. I want them to be connected by ethernet cable and be able to store GPS waypoints from one unit to the other. I really want down side imaging for sure on my console and I want down for sure on my trolling motor. Can anyone help?
