The spot lock function on the previous generation i-pilot would not hold your boat in as small of a radius as the pinpoint GPS on the Motorguide. I think Minn Kota solved that. I have used both the old and new generation on the Minn Kota i-pilot. This year, I went with the Motorguide for the simple reason that I prefer Lowrance electronics. The Motorguide motor will “talk” with the Lowrance HDS fish finders. Here is a summary of pros and cons for the MotorGuide Pinpoint GPS:
1. A little cheaper than Minn Kota
2. Will talk with Lowrance HDS
1. The remote control does not have an LCD screen, which is OK in itself, but it also means that you don’t have a display of the speed at which your boat is moving.
2. The link features between Minn Kota and Hummingbirds are better. You can tell your trolling motor to follow a contour on a map on the Minn Kota / Hummingbird combo. You cannot do that with the Motorguide / Lowrance combo. You can tell it to follow a track and go to a point, but it won’t follow a map contour.
If you are buying used (I should say Minn Kota motor older than 2017), I would go with the Motorguide. If new, the Minn Kota has an edge. I just didn’t want to switch brand on the fish finder. Not having the speed displayed on the remote has not been an issue for me yet. I haven't done any trolling so far with it. But it could become an issue on those rare occasions when I do.
