Sonar View

Sonar View presents a historical log of sonar returns. Depth is always
displayed. Readouts for temperature and speed are automatically displayed if
the appropriate accessory is connected. The most recent sonar returns are
charted on the right side of the window; as new information is received, the
older information is moved across the display to the left. A Digital Depth
Readout is displayed in the upper left corner. A scale with Upper and Lower
Depth Range readouts appears along the right edge of the Sonar View. The
scale indicates the distance from the surface of the water to a depth range
sufficient to show the bottom. Depth Range is automatically selected to keep
the bottom visible on the display, although you can adjust it manually as well
(see Sonar X-Press™ Menu). Five Digital Readouts display information from
optional-purchase accessories.
These information boxes can be customized to show only the information
desired (see Setup Menu Tab, Select Readouts).

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.
