24 Measure range and bearing

This section explains how to:

•find the range and bearing

•show and hide a VRM/EBL

•find the range and bearing with fixed VRM/EBL

•find the range and bearing with floating VRM/EBL

•set the EBL reference bearing

24.1Find range and bearing with the cursor

You can use the cursor to quickly find the precise range and bearing of a target from your vessel.

You can also use one, or both, of the VRM/EBL (Variable Range Markers/Electronic Bearing Lines), see "Find range and bearing with fixed VRM/EBL".

To find the range and bearing of a target with the cursor:

1.Select the target on your Radar screen.

2.The range and bearing is shown in the status bar at the top of the Radar screen, next to the cursor readout. Select the cursor readout to show the Lat/Long position (if GPS data is available).

3.When you are finished, select Return.

NOTE: If there's no heading data available from a heading sensor, the bearing readouts are relative to your vessel's head.

24.2Show/hide a VRM/EBL

You can show or hide one, or both, of the VRM/EBL (Variable Range

Markers/Electronic Bearing Lines) on your Radar screen.

Off is the default and hides the VRM/EBL.

To show or hide VRM/EBL data:

1.Display the Radar screen and control panel. If you can't see the

Range and Bearing button, select Return.

2.Select Range and Bearing.

3.Select VRM/EBL 1 to show the control panel for VRM1 and EBL1. If Show VRM/EBL 1 is toggled Off, select it to toggle it On. The Radar screen shows:

ƒVRM 1. A thin, circular, dotted line centered around your vessel. The radius is set at the most recent position.

ƒEBL 1. A thin dotted line extending from your vessel to the edge of your Radar screen. The bearing is relative to your vessel. The default angle is 045° Relative.
