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
TM
Menu). Five additional 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.
