5.4.1 The Bottom Lock Zoom
The Bottom Lock Zoom mode is activated when the Fish Finder is in Auto Range or
Bottom Lock mode (see Par. 5.6.3) and the Variable Depth Marker (VDM) is not
displayed on the screen.
In Bottom Lock Zoom mode the Fish Finder Echogram is automatically moved up/
down as to keep the Bottom Line always visible in the lower half of the screen.
NOTE Moving the Cursor key up/down displays the Variable Depth Marker (VDM)
switching the Fish Finder in Marker Zoom mode.
5.4.2 The Marker Zoom
The Marker Zoom mode is activated either when the Fish Finder is in Manual Range
mode (see Par. 5.6.3) 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 the
selected position. Moving the Variable Depth Marker (VDM) over the top or below the
bottom of the screen, automatically moves up/down the current zoomed Echogram
view and re-position the Variable Depth Marker (VDM) at the center of the screen.
NOTE Pressing [CLEAR] hides the Depth Cursor and if the Fish Finder is in Auto
Range or Bottom Lock mode switches into Bottom Lock Zoom mode.
