Premium Charts
CAUTION
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 g2 Vision

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 chartShowing Satellite Imagery on the
Navigation Chart, page 6.
Aerial Photos
: Shows marinas and other navigationally

direction on the Navigation chart or the Fishing chart. You must
also enable animated icons in the chart settings (
Showing Tides
and Current Indicators,
page

An indicator for a tide station appears on the chart as a vertical
bar graph with an arrow. A red arrow pointing downward
indicates a falling tide, and a blue arrow pointing upward
indicates a rising tide. When you move the cursor over the tide
station indicator, the height of the tide at the station appears
above the station indicator.
Current direction indicators appear as arrows on the chart. The
direction of each arrow indicates the direction of the current at a
specific location on the chart. The color of the current arrow
indicates the range of speed for the current at that location.
When you move the cursor over the current direction indicator,
the specific current speed at the location appears above the
direction indicator.
