I have to believe that sooner or later Johnson Outdoors is going to integrate the I-Pilot and the GPS function / processing capabilities of the GPS/Sonar units in a network (they already do it with their Cannon downriggers) so you can build trails and save as many trolling runs as you like on your sonar unit. Put this together with the Lakemaster chips and you will truly be able to troll contours on auto pilot with way more than the 3 allowed in memory by the I-Pilot. I hope that when this comes to be there is some amount of compatibility with legacy products, i.e. the expensive toys that we all have on our boats now.
