Navigating to a Marine Services Destination
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.
Note: Auto Guidance is available with a preprogrammed BlueChart g2 Vision data card.
