If you like to fish from the front the boat the Ultrex is superior to the Terova or Ultera. All great motors but the foot pedal on the Ultrex is awesome.
Love my 72″ Ulterra. I can deploy and retrieve it from my Humminbird. Never have to go up front in 3 – 4 footers to deal with it. Much safer when I fish alone.
With the integration of the trolling motor and graph, I do think that you need to decide what graph you want to eventually pair with it. When I bought my Terrova, Bird was the only integrated system. Now with Ghost out there it is possible for the Lowrance side to be integrated too. That should factor into your decision.
