I have lowrance, but they both work more or less the same. My setup it an Elite 9ti2 at the console, and an elite 9 ti at the bow. I have a chirp/down imaging transducer up front on the trolling motor and a transducer on the transom. I also have an Point-1, Gps/heading sensor. I use that when graphing to have accurate waypoints. Up front I use the heading sensor from it so I know which way I am facing when casting to waypoints easier, but the internal gps of the unit so I have accuracy when approaching marks.
This is how I have it setup now, but it can definitely be done with a single unit also.
