Navigating to a Point on the Chart
WARNING
All route and navigation lines displayed on the chartplotter are only intended to provide general route guidance
or to identify proper channels, and are not intended to be precisely followed. Always defer to the navaids and
conditions on the water when navigating to avoid groundings or hazards that could result in vessel damage,
personal injury, or death.
The Auto Guidance feature 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: The Fishing chart is available with premium charts, in some areas.
NOTE: Auto Guidance is available with premium charts, in some areas.

depth and minimum safe obstacle height.
