The race mode displays information crucial during the race, speed, heading and header/lift to the sailor.
Speed
Speed is calculated by the GPS unit by measuring the Doppler shift in GPS signals. It is displayed in
knots.
Heading
Heading (Course Over Ground) is calculated by the GPS unit by measuring the Doppler shift in GPS
signals.
Either true or magnetic heading can be displayed in compass mode by configuring the magnetic
declination on the ProStart. True heading is referenced to true north. Magnetic heading is referenced
to the local magnetic north. When using a magnetic compass in conjunction with the ProStart, the
magnetic heading is useful since both measurements will be referenced to magnetic north. By default
the compass displays true heading. To display magnetic heading the local magnetic declination must be
defined in device settings.
The ProStart displays heading only when your speed is greater than 1 knot, otherwise it will show a
heading of 0 degrees regardless of which direction you are actually moving.
Unlike a conventional magnetic compass, ProStart's compass reading depends on the direction you are
moving, not the direction the device is pointing. A major benefit of the ProStart over a conventional
Header/Lift each segment is 2.5 degrees
