It depends on how you like to fish. With the link you can set the trolling motor to follow a depth contour on the Hummingbird. I have the regular Terova. You can record a track and for the trolling motor to follow. I have not used that feature but it would be great when I am pulling boards in spring. Last year it was pretty crowded so I had to keep the remote handy to correct course. I do not have a transducer in my motor. I like to keep them seperate to make replacement a little easier on the wallet
The love for fishing is one of the best gifts you can pass along
