cartography, Fish Eye 3D provides an underwater view of the sea 

floor or lake bottom. The

keys adjust the view in the same 

way as the Mariner’s Eye 3D.

Sonar Cone—turn a cone on or 

off that shows the area covered 

by your transducer.

the sonar readings received 

by your transducer for the 

best combination of sonar and 

mapping. The setting is either 

on or off.

Use the Fishing chart for a 

detailed, unobstructed view of 

the bottom contours and depth 

soundings on the chart. 
The Fishing chart uses detailed 

bathymetric data on on a 

preprogrammed BlueChart g2 

Vision SD card, and is best for 

offshore deep-sea fishing.

To view the Fishing chart,

Fishing Chart.

  NOTE: You need an optional preprogrammed BlueChart g2 

Vision SD card for your region to view detailed fishing charts.

  NOTE: Because the detailed bathymetric information used 

by the Fishing Chart is recorded specifically for off-shore

applications, the Fishing Chart is not available on Inland Lakes 

Vision SD cards.
