Minn Kota's i-Pilot GPS system revolutionizes fishing in ways unimaginable a few years ago. Not only can anglers control their bow-mounted electric trolling motors wirelessly, a GPS function allows them to record routes up to 2 miles long and later retrace them -- with a push of a button. Also its "Spot-Lock'' feature can hold a boat nearly exactly on a position, and recall the spot for a return trip.
