I use my Onix and Terrova I Pilot Link to do quite a bit of contour trolling, many times on steep drop offs. It is a situation where a small lateral movement of the boat relative to the desired track can result in a significant change in bottom depth. If I am using the Terrova to follow an I Track (not "follow the contour") and the Onix is contolling the Terrova, is there a way to see the Cross Track error related to that track?
