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 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.
