Using Charts

The Fishing chart uses detailed bathymetric data on a preprogrammed BlueChart g2 Vision SD card, and is best for offshore deep-sea fishing.

Enabling High-Resolution Satellite Imagery

You can overlay high-resolution satellite images on the land, the sea, or both portions of the Navigation chart when using a preprogrammed BlueChart g2 Vision SD card.

To enable satellite imagery:

1.While viewing the Navigation chart, select Menu.

2.Select Chart Setup > Photos.

3.Select one of the following:

•Off—standard chart information is shown on the map.

•Land Only—standard chart information is shown on water with photos overlaying the land.

•Photo Map—photos overlay both the water and the land at a specified opacity. The higher you set the percentage of opacity, the more the satellite photos will cover both land and water.

NOTE: When enabled, the high-resolution satellite images are present only at lower zoom levels. If you cannot see the high-resolution images in your BlueChart g2 Vision region, zoom in using the RANGE

(+) key (GPSMAP 4000 series) or touch (GPSMAP 5000 series). You can also try setting the detail level higher.
