Using BlueChart g2 Vision Optional BlueChart g2 Vision preprogrammed SD cards allow you to get the most out of your GPSMAP 640. In addition to detailed marine charting, BlueChart g2 Vision has the following features: • Mariner's Eye 3D-provides a view from above and behind the boat for a three‑dimensional navigation aid. The BlueChart g2 Vision Mariner's Eye 3D is more detailed than the standard Perspective 3D screen. • Fish Eye 3D-provides an underwater, three-dimensional view that visually represents the sea floor according to the information on the chart. • Fishing Charts-displays 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. • Detailed Roads and POI data-displays roads, restaurants, and other points of interest (POIs) along the shore. • Auto Guidance-uses specified safe depth, safe height, and chart data to suggest the best passage to your destination. Marine Mode: Using Charts Using Mariner's Eye 3D When using a BlueChart g2 Vision SD card, you can view the Mariner's Eye 3D screen. The Mariner's Eye 3D screen is similar to the Perspective 3D screen (page 10), but renders a true 3D screen. This view is helpful when navigating tricky shoals, reefs, bridges, or channels, and is beneficial when trying to identify entry and exit routes in unfamiliar harbors or anchorages. Mariner's Eye 3D provides a three‑dimensional view of both the shore and the sea floor. To access the Mariner's Eye 3D screen from the Home screen, touch Charts > Mariner's Eye 3D. As with the Perspective 3D screen, touch the button to move the view closer to your boat and lower to the water. Touch the button to move the view away from the boat. This is momentarily indicated by the scale ( ) at the bottom of the screen. Touch and drag the map to the left or the right to pan the 3D perspective. GPSMAP 640 Owner's Manual 11
