Typically your boat's position is at the centre of the display, and its dead ahead bearing is indicated by a
vertical heading line, known as the Ship's Heading Marker (SHM).
Remember that the radar picture may vary from visual observations that you make; a nearby small object may
appear the same size on the screen as a distant large object. However, with experience the approximate size
of different objects can be determined by the relative size and brightness of the echoes.

Range rings
Use the range rings to gauge
the approximate distances
between two points or from
your boat.
VRMs
Align a VRM on a target to
display its range from your
boat:
EBLs
Align an EBL on a target to
display its bearing relative to
your boat's heading:
Combined VRM/EBL
Combine a VRM and EBL to
measure range and bearing
of specified target.
