I'll check on my E120 later when I'm on the boat. However I can't see much point in seeing contour lines much beyond say 100m, deeper than that, what difference does it make to a surface vessel?
My original post states :- "I have tried to get it to show depth contours so as I can troll for tuna around the various drop off points. eg 500m and beyond"
