Sonar View
Sonar View presents a historical log of sonar returns. The most recent sonar
returns are charted on the right side of the display. As new information is
received, the historical information scrolls left across the display.
Upper and Lower Depth Range numbers indicate the distance from the
surface of the water to a depth range sufficient to show the bottom.
Depth is automatically selected to keep the bottom visible on the display,
although you can adjust it manually as well (see Sonar X-Press™ Menu).
Digital Readouts shown on the display will change based on the Select
Readouts settings or the optional-purchase accessories attached (see
Setup Menu Tab: Select Readouts).
Freeze Frame - Use the 4-WAY Cursor Control key to freeze the display
and move the cursor over a sonar return. The depth of the sonar return
will be displayed at the bottom of the screen in the cursor information
box.
