Using Fish Eye 3D
Using the depth contour lines of the BlueChart g2 Vision 
cartography, Fish Eye 3D provides an underwater view of the sea 
floor or lake bottom.

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.
Tracks—turn the track log on or 
off.

Using Fishing Charts
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 the 
BlueChart g2 Vision SD card, 
and works best for offshore 
deep-sea fishing.
To view the fishing chart, 
from the Home screen select
Charts
>
Fishing Chart.
  NOTE: An optional BlueChart g2 Vision preprogrammed SD card 
for your region is needed 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 the  
GPSMAP 430/430s/430x/430sx (inland) units.
