True motion
In True motion your vessel, and moving targets, move across the Radar screen as you travel.
All stationary objects remain in a fixed position. When the vessel’s symbol reaches the edge of
the screen, the radar image will be redrawn with the vessel symbol re-positioned in center of
the screen.
When True motion is selected, the menu will expand to include a reset true motion option.
This allows for manually resetting the radar image and vessel symbol to screen center.
Measuring range and bearing to a target
Using the cursor
The cursor is by default not shown on the radar image.
When you tap the radar panel the cursor will be visible, and the
cursor position window will be activated, showing range and bearing
from your vessel to cursor position.
Range rings
The range rings are displayed at preset distances from the vessel based on the radar range.
You can use the range ring to estimate the distance to a radar echo.
EBL/VRM
The electronic bearing line (EBL) and variable range marker (VRM) allows quick measurements
of range and bearing to vessels and landmasses within radar range. Two different EBL/VRMs
can be placed on the radar image.
The EBL/VRM is by default positioned from the center of the vessel. It is however possible to
offset the reference point to any selected position on the radar image.
You can position EBL/VRM by using the cursor, and edit the marker
position as described below.
When positioned, you can quickly turn the EBL/VRM on/off by tapping
the relevant markers on the data bar.
