Using Bluechart G2 Vision; Using Mariner's Eye 3D - Garmin GPSMAP 640 Owner's Manual

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.
