i-Pilot is the anchor "spot lock" feature.
i-Pilot Link will have the same anchor "spot lock" feature as the i-Pilot yet the link will connect to a compatible Humminbird unit with a LakeMaster Chart card and will have the follow the contour and Go-To feature.
Is the link somthing somthing you would use as a crappie fishermen?
If you troll bottom contours, the Follow-the-Contour feature with Lakemaster mapping would be a plus.
LINK gives you more Spotlock waypoint memory.
