VRM and EBL

The variable range marker (VRM) and the electronic bearing line (EBL) measure the distance and bearing from your boat to a target object. On the Radar screen, the VRM appears as a circle that is centered on the present location of your boat, and the EBL appears as a line that begins at the present location of your boat and intersects the VRM. The point of intersection is the target of the VRM and the EBL.

You can set up to two independent VRM/EBL indicators on the chartplotter radar screen.

Showing and Adjusting a VRM and EBL

You can adjust the diameter of a VRM and the angle of an EBL, which moves the intersection point of the VRM and the EBL. A VRM and EBL configured for one mode are applied to all other radar modes.

  1. From a radar screen, select Options > Radar Options > VRM/EBLs.
  2. Select VRM/EBL 1 or VRM/EBL 2 to enable the VRM/EBL lines on the radar screen.
  3. To adjust the position of a VRM/EBL target, select Menu button > Adjust, and select a new location for the intersection point of the VRM and the EBL
  4. Select Done.

Quickly Measuring the Range and Bearing to a Target Object

  1. From a Radar screen, select the target location.
  2. Select VRM/EBLs.

    A list of VRM/EBL options appear.

  3. Select Drop VRM/EBL 1 or Drop VRM/EBL 2.

    The VRM/EBL intersection is set at the target location. The range and bearing to the target location appear in the upper-left corner of the screen.

Changing an EBL Bearing Reference

You can change the bearing reference of the EBL so that it uses the heading of the boat or north.

  1. From a radar screen, select Options > Radar Options > VRM/EBLs.
  2. If necessary, select VRM/EBL 1 or VRM/EBL 2 to enable the VRM/EBL lines on the radar screen.
  3. Select Menu button > EBL Reference to change the EBL reference.

    North uses the cardinal direction of north as a reference, and Relative uses the heading of the vessel as a reference.

    NOTE: You can have different EBL Reference settings for each of the VRM/EBLs.

Changing the Origin of a VRM and EBL

You can change the origin of the VRM and EBL lines so that they center on a location other than your vessel.

  1. From a radar screen, select Options > Radar Options > VRM/EBLs.
  2. If necessary, select VRM/EBL 1 or VRM/EBL 2 to enable the VRM/EBL lines on the radar screen.
  3. Select Menu button > Set Floating Origin.
  4. Select a location on the radar screen where you want to center the VRM and EBL and select Done

To return the VRM and EBL so that it is centered on the vessel, select Reset Floating Origin.

Using VRM and EBL Quick Actions from the Radar Screen

You can quickly set and adjust VRM and EBLs using shortcuts directly from the radar screen.

  1. Select an object or location on radar screen and select VRM/EBLs from the shortcut menu.
  2. Select an option to quickly set or adjust a VRM and EBL:

    • Drop VRM/EBL 1 or Drop VRM/EBL 2: Sets the intersection point of the VRM and EBL at the selected location.

    • Disable VRM/EBL 1 or Disable VRM/EBL 2: Disables the VRM and EBL and clears it from the radar screen.

    • Float VRM/EBL 1 or Float VRM/EBL 2: Sets the origin point of the VRM and EBL at the selected location instead of your vessel.

    • Reset VRM/EBL 1 Origin or Reset VRM/EBL 2 Origin: Resets the origin point of the VRM and EBL so it is centered on your vessel.
