obstructions, and cable areas.
Navigating to a Point on the Chart
CAUTION
The Auto Guidance feature of the BlueChart g2 Vision data card is based on electronic chart information. That
data does not ensure obstacle and bottom clearance. Carefully compare the course to all visual sightings and
avoid any land, shallow water, or other obstacles that may be in your path.
When using Go To, a direct course and a corrected course may pass over land or shallow water. Use visual
sightings and steer to avoid land, shallow water, and other dangerous objects.
: The Fishing chart is available if you use a BlueChart g2 Vision SD card or a BlueChart g2 SD card, or
if your built-in map supports Fishing charts.
