The I-Pilot 'Link' does a lot more then just follow contours. I can control my Terrova right from my HB without every touching the trolling motor. Go to Waypoint, troll to waypoint, stop at waypoint, make a route, follow a route, etc etc. It's the most useful tool I've got in the boat. I spend more time messing around with that stupid thing then I do fishing (The oldman doesn't appear to complain about this too much )
