Mariner’s Eye 3D: Shows a detailed, three-dimensional view from above
and behind the boat (according to your course) and provides a visual
navigation aid. This view is helpful when navigating tricky shoals, reefs,
bridges, or channels, and when trying to identify entry and exit routes in
unfamiliar harbors or anchorages.
NOTE: Mariner’s Eye 3D and Fish Eye 3D chart views are available with
premium charts, in some areas.
Fish Eye 3D: Provides an underwater view that visually represents the
sea oor according to the chart information. When a sonar transducer is
connected, suspended targets (such as sh) are indicated by red, green,
and yellow spheres. Red indicates the largest targets and green indicates
the smallest.
Fishing Chart: Provides a detailed view of the bottom contours and depth
soundings on the chart. This chart removes navigational data from the
chart, provides detailed bathymetric data, and enhances bottom contours
for depth recognition. This chart is best for offshore deep-sea shing.
