Auto pilot is another option I've considered. Primary use is trolling. My concern was response time in breezy conditions. Boat has a cabin making it easier to pull through conditions than to push. Contour following isn't sumpin I do often but is easy enough to do manually. Maybe do both?
if you go with a bow mount for trolling, it is a must to get a skeg extension like a leelock. otherwise they kinda suck imo.
Anyone who uses autopilot and spotlock when fishing popular fisheries and crowded conditions needs to get throat punched. I about ran over some dip*censored* in a windshield tin can about 5 times in one day at possession last season.
