Views
The views available on your Matrix™ Fishing System are:
Sonar View
Zoom View
200/83 kHz Split Sonar View
Big Digits View.
Sonar View is the default view. When the VIEW key is pressed, the display cycles
through the available views. When the EXIT key is pressed, the display cycles
through the available views in reverse order. Any view can be hidden or displayed as
part of the view rotation using Select View from the Views Tab.
NOTE: When you change any menu settings that affect the sonar, the view will update
immediately (i.e. you don’t have to exit the menu to apply the change to the screen).
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.
Freeze Frame - Pressing any arrow on the 4-WAY Cursor Control key will freeze the
screen in the Sonar View and a cursor will be displayed on the screen. The cursor can
be positioned on the display using the 4-WAY Cursor Control key to determine the
depth of any sonar return. The RTS® Window continues to update in Freeze Frame.
In addition, see the effects of menu setting changes with Instant Image Update.
Pressing EXIT will exit Freeze Frame and the display will start to scroll. Freeze Frame
is only available in the Sonar View.
