Moving the Cursor key up/down displays the Variable Depth Marker (VDM) switching the Fish Finder in
Marker Zoom mode.
6.4.2 THE MARKER ZOOM
The Marker Zoom mode is activated either when the Fish Finder is in Manual
Range mode (see Par. 6.6.3) or the Depth Cursor is displayed on the screen.
In Marker Zoom mode the Fish Finder Echogram position is controlled by moving
the Variable Depth Marker (VDM) and pressing and holding 'ENTER' for 1 second on
