Adjustment Menu Options
Range— sets the display depth range used for viewing. The unit can be set to automatically track
the bottom or set to a user-specifi ed depth range. Auto mode displays the most information pos-
sible while continuously showing the bottom.
Zoom— used to quickly select a display zoom scale or split the display. When a scale other than
‘No Zoom’ is selected, the Adjustment Menu displays a new selection labeled ‘View.’ The Zoom
setting is divided into six display levels:
2X Split: shows two reduced-size sonar pictures at the same time. The right half of the display
screen shows the complete sonar picture at its original scale. The left half shows a portion of the
original picture at 1/2 depth scale.
2X Zoom: displays the 2X zoomed picture on the full screen and does not show the original
depth scale.
4X Split: shows two reduced pictures; the right at the original depth scale and the left at 1/4 the
original depth scale.
4X Zoom: displays only the 4X zoomed picture on the full screen. However, if ‘Dual Frequency
Display’ is set to ‘Split’, then a 50/200kHz split screen will be displayed.
Btm (Bottom) Split: shows two reduced pictures; the right at the original depth scale and the
left showing sonar returns from the bottom up. All target depths will read as a distance form the
bottom.
Btm (Bottom) Lock: displays only the Bottom Lock picture (returns from the bottom up) on the
full screen. However, if ‘Dual Frequency Display’ is set to ‘Split’, then a 50/200kHz split screen
will be displayed.
