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.
