Sonar View
Sonar View presents a historical log of sonar returns. The most recent sonar
returns are charted on the right side of the window. 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.
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.
