each of which are labelled with the appropriate measurement.

easier to position the marker).

Resume.
3. Select the location you want to place the marker.
4. Open the Fishfinder context menu .
5. Select Place Marker .
Once placed you can move the marker by selecting Move
Marker from the Fishfinder context menu.
Note: The VRM is only available in Bottom Lock mode when
viewing the display mode in Split screen.
