regular intervals to indicate the depth from the surface.
These lines can be switched on or off using the

Measuring depth and distance with VRM
You can use a Variable Range Marker (VRM) to determine an
object’s depth and distance behind your vessel. These markers
consist of a horizontal (depth) line and a vertical (distance) line,
each of which are marked with the appropriate measurement and
are controlled individually.
From the main shnder screen:
1. Press the PRESENTATION softkey.
2. Press the SCROLL softkey to pause the display. This may make
it easier to position the VRM over the desired object.
3. Press the VRM softkey to open the VRM toolbar.
4. Press the VRM softkey again until the ON option is selected.
5. Measure the depth or distance:
• Press the VRM RANGE softkey to measure distance, or
• Press the VRM DEPTH softkey to measure depth.
6. Use the rotary control or touchscreen to measure the distance
or depth to your target.
7. Press the OK button to save the position.
Note: The VRMs used in the shnder application are unrelated
to the VRMs used in the radar application.
