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.

How do I measure distances, ranges and bearings with the radar?

VRMs

Align a VRM on a target to display its range from your boat:

e.g.

ADJUST VRM

 

 

1.800nm

 

 

Combined VRM/EBL

Combine a VRM and EBL to measure range and bearing of specified target.

e.g.

ADJUST VRM

ADJUST EBL

1.800nm

30.00S

 

 

EBLs

Align an EBL on a target to display its bearing relative to your boat's heading:

e.g.

ADJUST EBL

30.00S

Rings 1/2nm Range rings

Use the range rings to gauge the approximate distances between two points or from your boat.

Note: Range/bearing also displayed when VRM/EBL selected with the cursor.
