Premium Charts
All route and navigation lines displayed on the chartplotter are
only intended to provide general route guidance or to identify
proper channels, and are not intended to be precisely followed.
Always defer to the navaids and conditions on the water when
navigating to avoid groundings or hazards that could result in
vessel damage, personal injury, or death.
The Auto Guidance feature is based on electronic chart
information. That data does not ensure obstacle and bottom
clearance. Carefully compare the course to all visual sightings,
and avoid any land, shallow water, or other obstacles that may
be in your path.
NOTE: Not all models support all charts.
Optional premium charts, such as BlueChart
you to get the most out of your chartplotter. In addition to
detailed marine charting, premium charts may contain these
features, which are available in some areas.
Mariner's Eye 3D: Provides a view from above and behind the
boat for a three-dimensional navigation aid.
Fish Eye 3D: Provides an underwater, three-dimensional view
that visually represents the sea floor according to the
information on the chart.
Fishing Charts: Shows the chart with enhanced bottom
contours and without navigational data. This chart works well
for offshore deep-sea fishing.
High Resolution Satellite Imagery: Provides high-resolution
satellite images for a realistic view of the land and water on
the Navigation chart
(Showing Satellite Imagery on the

Aerial Photos: Shows marinas and other navigationally
significant aerial photos to help you visualize your
