[. . . ] 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-PressTM Menu). Sonar View 1 6 7 8 9 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 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. 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. SONAR ZOOM VIEW Sonar Zoom View increases the displayed resolution to separate sonar returns that are very close together, such as those caused by fish suspended close to the bottom or within structure. In Zoom View, the display is split to show a narrow slice of the full range view on the right and the zoomed view on the left. The full range view on the right also contains the Zoom Preview Box that shows what part of the full range view is shown in zoom view on the left; the Zoom Preview Box tracks the bottom in the full range view. As the depth changes, the zoomed view updates automatically to display a magnified image of the bottom. The Zoom Preview Box shows where the zoomed view is in relation to the full range view. The Zoom Level, or magnification, is displayed in the lower left corner and can be changed to suit conditions (see Sonar X-PressTM Menu: Zoom Level). Upper and Lower Zoom Depth Range numbers indicate the depth of the water which is being viewed. 2 5 10 11 3 4 12 1 2 3 4 5 6 Depth Triplog Temperature Speed Cursor Depth of Cursor Depth below Cursor 7 Distance to Cursor 8 Bearing to Cursor 9 RTS® Window 10 Sonar Color Bar 11 Lower Depth Range 12 33 93x_Man_531370-1_A - vs4. qxd 2/18/2005 11:12 AM Page 39 Freeze Frame - Pressing any arrow on the 4-WAY Cursor Control key will freeze the screen in the Sonar Zoom View and a cursor and cursor dialog box will be displayed on the screen.

SPLIT SONAR VIEW (937c DF Combo and 931c DF models only) Split Sonar View displays sonar returns from the 50 kHz wide beam on the left side of the screen and displays sonar returns from the 200 kHz narrow beam on the right side of the screen. You can use the Split Sonar View to make side by side comparisons between the sonar returns from the 50 kHz wide beam and the 200 kHz narrow beam.

Big Digits on this view provide digital data in a large, easy-to-see format. When you press the 4-WAY Cursor key in the Bird's Eye View, the position of the eye point will shift. This allows you to move and turn the eye point so that you can look off to the sides, or even behind the boat. Pressing the RIGHT or LEFT arrow keys on the 4-WAY Cursor key turns the eye point right or left, while pressing the UP arrow key moves the eye point forward, and pressing the DOWN arrow key moves the eye point backward.
