Humminbird 957C, 917C manual Sonar View

Sonar View

Sonar View presents a historical log of sonar returns. 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 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).

Freeze Frame - Pressing any arrow on the 4-WAY Cursor Control key will freeze the screen in the Sonar View and a cursor and cursor dialog box 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.

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.
