You can also do this same thing using the pencil and making consecutive marks as the plot moves. If you are submerged use the same process but put your line on the very tip of each sonar contact line that is drawn on the map (these lines may be an option--I don't recall. They appear on my map but maybe not on yours).

That wouldn't work very well with map contact updates turned off.
