bow of the boat in the direction of travel. Angle markers indicate
relative position from the heading or course over ground, which
are helpful for casting or finding reference points.

Premium Charts
WARNING
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
®
g3 Vision, allow
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
Navigation Chart , page 6 ).
Aerial Photos : Shows marinas and other navigationally
significant aerial photos to help you visualize your
surroundings ( Viewing Aerial Photos of Landmarks ,
page 6 ).
Detailed Roads and POI data : Shows detailed road and point
of interest (POI) data, which includes highly detailed coastal
roads and POIs such as restaurants, lodging, and local
attractions.
Auto Guidance : Uses specified information about your vessel
and chart data to determine the best path to your destination.
Viewing Tide Station Information
on the chart indicates a tide station. You can view a detailed
graph for a tide station to help predict the tide level at different
times or on different days.
NOTE: This feature is available with premium charts, in some
areas.
1
From the Navigation chart or Fishing chart, select a tide
station.
Tide direction and tide level information appear near .
2
Select the station name.
Animated Tide and Current Indicators
NOTE: This feature is available with premium charts, in some
areas.
You can view indicators for animated tide station and current
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 5 ).
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.
Color Current Speed Range
Yellow 0 to 1 knot
Orange 1 to 2 knots
Red 2 or more knots
