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 labelled with the appropriate measurement.
From the fishfinder application:
1. Select Menu
2. Select Scroll so that Pause is highlighted (This may make it
easier to position the marker).
Selecting Scroll will switch the scroll between Pause and
Resume.
3. Open the fishfinder context menu.
4. Select Place Marker.
5. Select the location you want to place the marker.
Note: Once placed you can move the marker by selecting
Move Marker from the fishfinder context menu.

Depth Target ID — depths are displayed against recognized
targets. The sensitivity of these IDs is directly linked to the Fish
Alarm sensitivity; the greater the fish alarm sensitivity, the greater
the number of labelled returns.
Depth lines — horizontal dashed lines drawn at regular intervals to
indicate the depth from the surface.
Horizontal VRM marker — indicates the depth of the target.
Vertical VRM marker — indicates the distance behind your vessel.
Cursor Depth — this is the depth of the cursor position.
Cursor Range — this is the range from your vessel to the cursor
position.
