Review the course indicated by the magenta line.

NOTE: 

When using Auto Guidance, a gray segment within 

any part of the magenta line indicates that Auto Guidance 

cannot calculate part of the Auto Guidance line. This is due to 

the settings for minimum safe water depth and minimum safe 

obstacle height.

5

Follow the magenta line, steering to avoid land, shallow 

water, and other obstacles.

Heading Line and Angle Markers

The heading line is an extension drawn on the map from the 

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.

Setting the Heading and Course Over Ground Lines

You can show the heading line and the course over ground 

(COG) line on the chart.
COG is your direction of movement. Heading is the direction the 

bow of the boat is pointed, when a heading sensor is connected.

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

®

, 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.
