That data does not ensure obstacle and bottomclearance. Carefully compare the course to all visual sightings,and avoid any land, shallow water, or other obstacles that maybe in your path.When using Go To, a direct course and a corrected course maypass over land or shallow water. Use visual sightings, and steerto avoid land, shallow water, and other dangerous objects.NOTE: Some chart views are available with premium charts, insome areas.To navigate, you must choose a destination, set a course orcreate a route, and follow the course or route. You can followthe course or the route on the Navigation chart, Fishing chart,Perspective 3D chart view, or Mariner’s Eye 3D chart view.You can set and follow a course to a destination using one ofthree methods: Go To, Route To, or Auto Guidance.Go To: Takes you directly to the destination. This is thestandard option for navigating to a destination. Thechartplotter creates a straight-line course or navigation line tothe destination. The path may run over land and otherobstacles.Route To: Creates a route from your location to a destination,allowing you to add turns along the way. This option providesa straight-line course to the destination, but allows you to addturns into the route to avoid land and other obstacles.Auto Guidance: Uses the specified information about yourvessel and chart data to determine the best path to yourdestination. This option is available only when using acompatible premium chart in a compatible chartplotter. ItNavigation with a Chartplotter 13
