Center
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.
