Does the follow contour function work with the Navionics chip or only the Lake master? I jst got a second fish finder for the bow and I have the Lakemaster chip that I have been using, but also have a Navionics Premium that I had in an older fish finder. Just wondering if the contour function worked on either chart chip or only the Lakemaster.
