Charts and 3D Chart Views
The chartplotters have a basic imagery map. The charts and 3D
chart views listed below are available on the chartplotter. The
charts and views that are available depend on the map data and
accessories used.
You can access the charts and chart views by selecting Charts.
Navigation Chart: Shows navigation data available on your
pre-loaded maps and from supplemental maps, if available.
The data includes buoys, lights, cables, depth soundings,
marinas, and tide stations in an overhead view.
Perspective 3D: Provides a 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 is beneficial when
trying to identify entry and exit routes in unfamiliar harbors or
anchorages.
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 floor according to the chart information.
When a sonar transducer is connected, suspended targets
(such as fish) are indicated by red, green, and yellow
spheres. Red indicates the largest targets and green
indicates the smallest.
NOTE: Mariner's Eye 3D and Fish Eye 3D chart views are
available with premium charts, in some areas.
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 fishing.
NOTE: The offshore Fishing chart is available with premium
charts, in some areas.
Radar Overlay: Superimposes radar information on the
Navigation chart or the Fishing chart, when the chartplotter is
connected to a radar. This feature is not available with all
models.
