I have the 57" on a champion 202, had nothing but minn kota for years although I did try a couple of motorguide (they suck the big one imo).
what mike said is about the same for me, really makes it a lot easier for an old guy to sit on a spot and fish.
updates are super easy since they come thru your phone and the app.
one thing I have noticed is when you calibrate the compass in the tm do the 360 slow as you can, I rushed it the first time and while it worked it was off some, recalibrated and now anchor lock is spot on.
mine does stick out some but I can live with it as is, had the fortrex 52" before and the garmin is about the same as it was for overhang.
one nice feature is you can run it 24v or 36v with no modifications needed, just hook it up to either voltage and go. another is you have a space in the mount to accommodate the livescope transducer, you can barely see mine behind the strap. everything ties together with wifi instead of bluetooth, all built in and works great.
I would recommend it over the others after fishing boats with ultrex and ulterra.
