Re: Which one would you buy
I have the i-pilot and a Lowrance, the transducer is compatible, that's not a problem, you just can't use the GPS in the FF to control the motor, I don't use mine that way so it doesn't matter. I use the GPS in the motor, it stores routes and positions on its own. If I upgrade to a Humminbird it would be for the 360 feature, it seams like it would work better than sidescan to pinpoint fish.
I really like the Minn Kota, it works very well, I haven't used a MG so I have no idea how they compare.
