Changing Course - NorthStar EXPLORER AP380 Installation And Operation Manual

Tip: It is possible to change steering modes
while in AUTO mode. For example it is helpful
to use Compass mode to control the boat when
setting up a GPS route, then change directly to
GPS mode.
Note for sailing boats:
• The AP380 is not recommended for use in
light, changeable or gusty winds.
• Take care when running downwind to avoid
an accidental gybe.
• Wind mode requires the wind instrument to
be accurately calibrated.
