I also have a Terrova with I-Pilot link. Best trolling motor I have used. Spot lock is great and holds you dead on any spot you pick. Auto pilot works great as a trolling motor or when drifting in a river and you want to keep the boat drifting a certain way with the current. I use this all the time in the Niagara. Don't think you can go wrong with either Terrova or Ulterra. I am going to upgrade to an Ulterra cause I'm getting lazy and want the auto deploy. LOL
