Radar motion modes overview
The motion mode controls the relationship between the radar and
your boat. There are two modes:
• Relative motion.
• True motion.
The selected motion mode is displayed in the status bar. The default
setting is relative motion with zero offset.
Relative Motion (RM) with optional Vessel Offset
When the motion mode is set to Relative, the position of your boat
is fixed on the screen and all the targets move relative to the boat.
You can specify whether the boat is fixed in the centre of the window
(0 offset) or offset by 1/3 or 2/3 to increase the view ahead, as
shown below:
D6842-2

The default motion mode is “Relative”, with zero offset.
True Motion (TM)
When the motion mode is set to True, fixed radar targets maintain a
constant position and moving vessels (including your boat) travel
in true perspective to each other and to fixed landmasses on the
screen. As the boat’s position approaches the edge of the screen,
the radar picture is automatically reset to reveal the area ahead.
Note: If heading and position data become unavailable when
True motion is selected, a warning message will be shown, the
mode will revert to relative motion and be noted in the status bar
in brackets, for example, (TM).
Note: It is not possible to select True Motion when the orientation
is set to Head Up.
