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 top of the screen in the cursor
dialog box.
NOTE: If the Depth number is flashing, it means that the unit is having trouble
locating the bottom. This usually happens if the water is too deep, the transducer
is out of the water, the boat is moving too fast, or for any other reason that the
unit can’t accurately receive continuous data.
