Using Charts

Sonar Data—visually shows the sonar readings received by your transducer for the best 

combination of sonar and mapping.
tracks—turns the track log on or off.
Data Bars—shows or hides cruising, navigation, fishing, fuel, or sailing numbers (

).

Use the fishing chart for a detailed view of the bottom contours and depth soundings on the chart.

The fishing chart uses detailed bathymetric data on a preprogrammed BlueChart g2 Vision SD card, 

and is best for offshore deep-sea fishing.

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.

  Note: When enabled, the high resolution satellite images are only present at lower zoom levels. If 

you cannot see the high resolution images in your BlueChart g2 Vision region, either zoom in further 

by touching the   and   buttons, or set the detail level higher by touching
