Tim, if your thinking of upgrading with the new remote for your existing motor to be more accurate, not going to happen. The older terrova is not going to be able to upgrade to the new technology. Sad to Say.The boat I just bought had a 2014 model Terrova Riptide on it with I pilot and I have used it several times. As far as the trolling motor goes it works great. The remote is handy when you have to go to the back of the boat for something and need to hold in a general area. I dropped a marker buoy on a brush pile and turned the boat into the wind to give the spot lock a fair chance. If you think they will hold you in a small area, you are going to be highly disappointed. I had full signal strength and the boat would drift 20 to 25 ft off of the buoy marker before the trolling motor would re-engage. When it finally did it would go at times 10 to 15 ft left or right of the marker and sometimes 15 ft past it. That was in a 5 to 10 mph wind. It was designed to hold the boat within a circle so big and that's a pretty big circle. They say the XI-5 is more accurate with spot lock. The Terrova is quiet on lower speeds and that's the most important thing for me spider rigging and fishing shallow water. At .01 to .03 mph I can't hear it running but I'm half deaf. Remote is simple to read and easy to use. Battery draw is also very low. The new ones with blue tooth are supposed to be more accurate but I am going to wait and see reviews on them before I spend 350.00 on a new remote and blue tooth pod. Last thing a lot of interference if you try to mount a transducer on the motor especially with structure scan. I had to buy a separate transducer pole and mount it on the opposite side of the boat. Overall the Terrova will do anything I need it to and the speed control is really accurate because I checked it with GPS. When spider rigging, that's more important to me than spot lock.
