Navigating to a Point on the Chart 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. When using Go To, a direct course and a corrected course may pass over land or shallow water. Use visual sightings, and steer to avoid land, shallow water, and other dangerous objects.

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. 6 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. 1 From a chart view, select Menu > Chart Setup > Chart Appearance > Heading Line. 2 If necessary, select Source, and select an option: • To automatically use the source available, select Auto. • To use the GPS antenna heading for COG, select GPS Heading (COG). • To use data from a connected heading sensor, select Heading. • To use data from both a connected heading sensor and the GPS antenna, select COG and Heading. This displays both the heading line and the COG line on the chart. 3 Select Beeper and Display, and select an option: • Select Distance > Distance, and enter the length of the line shown on the chart. • Select Time > Time, and enter the time used to calculate the distance your boat will travel in the specified time at your present speed. Turning on Angle Markers You can add angle markers to the map along the heading line.

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 safe depth, safe height, and chart data to determine the best course 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. Charts and 3D Chart Views 5
