Plotter display
The plotter display shows your ships position, track history,
bearing and range to target, course and speed over ground and
zoom range .
The Plotter page allows you to view your current location . It also
displays a record of your track along with nearby Waypoints . The
‘ship’ on the screen shows your present position and heading
(the bow of the ship points in the direction of travel . At the
corners of the screen are displayed the Bearing (BRG), Range
(RNG), Course over Ground (COG) and Speed Over Ground
(SOG) relative to your destination . Your present Latitude and
Longitude is displayed at the bottom of the screen .
If the unit is in ‘cursor’ mode, the Latitude and Longitude will
display the position of the cursor on the screen and the BRG
and RNG will display values relative to the cursor .
hIGhWay dIsPlay
The highway display provides a 3D view of your own vessel’s
progress towards a destination (Waypoint), along with
associated navigation data .

The Navigation display provides a sliding compass scale . The
vessel arrow in the centre shows your vessel’s present compass
heading . The Waypoint Marker shows the direction of your
destination Waypoint relative to your track .
Note:
The compass scale requires your vessel to be moving in
order to determine your direction . It does not work while your
vessel is stationary .
The centre of the page features a sliding compass scale that
shows your course over ground (current track) while you are
moving . Your present course over ground is indicated by the
vessel pointer in the centre of the display . A destination marker
shows the Bearing to your destination Waypoint relative to your
current track (COG) . The compass scale and Waypoint marker
work independently to show at a glance the direction of your
movement and direction to your destination .
e .g . if the destination marker is to the left or right of your
vessel’s current track you should steer towards the marker until
it is directly above your vessel’s pointer . Once your vessel’s
pointer is aligned with the destination marker, you are travelling
towards your destination .

When a destination is set the compass page will guide you to
your destination with digital readouts and a graphic compass
display which includes a bearing pointer . The Compass page is a
good alternative to the highway page when travelling at slower
speeds or when making frequent directional changes such as
when straight line navigation is not possible due to obstructions
or terrain .
Note
that the compass page requires your vessel to be moving
in order to determine your direction . It does not work while your
vessel is stationary .
The centre of the page features a rotating compass that shows
your course over ground (current track) while you are moving .
Your present course over ground is indicated at the top of the
compass ring . A Bearing Pointer in the centre of the compass
