Down Imaging Sensitivity
Use Down Sensitivity to control how the sonar returns appear on the display. Increase the
sensitivity to reveal weaker returns that may be of interest, especially in very clear water or greater
depths. Decrease the sensitivity to eliminate the clutter from the display that is sometimes present
in murky or muddy water. See the
Down Imaging X-Press Menu: Down Sensitivity for more
information.
Freeze Frame and Active Cursor
Freeze Frame and Active Cursor: Press any arrow on the 4-WAY Cursor Control key, and the
screen will freeze and a cursor will be displayed. Use the 4-WAY Cursor Control key to move the
cursor over a sonar return, and the depth of the sonar return will be displayed in the cursor dialog
box.
DI Zoom: Use DI Zoom to see returns near the cursor location at a higher magnification. For more
information, see Views: Down Imaging View.
