Views

The views available on your FishFinder are:

•Sonar View

•Zoom 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 Advanced Setup Menu.

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.

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.

Understanding Sonar History

It is important to understand the significance of the Humminbird® display. The display does NOT show a literal 3-dimensional representation of what is under the water. Each vertical band of data received by the control head and plotted on the display represents something that was detected by a sonar return at a particular time. As both the boat and the targets (fish) may be moving, the returns are only showing a particular segment of time when objects were detected, not exactly where those objects are in relation to other objects shown on the display.

Real Time Sonar (RTS®) Window

A Real Time Sonar (RTS®) window appears on the right side of the display in the Sonar View only. The RTS® Window always updates at the fastest rate possible for depth
