Zoom Manual Mode, Grayline | Lowrance electronic X-65 guide

ZOOM - MANUAL MODE

The Z-IN (zoom-in) and Z-OUT (zoom-out) keys enlarge and reduce the size of the echoes on the screen when the unit is in the manual mode, the same as the automatic mode.

However, you can manually adjust the zoom when the unit is in the manual mode. To do this, press the MENU key, then press the right or left arrow keys until the "CHART ZOOM" menu appears. Now press the right arrow key. A screen similar to the one at right appears.

This is the split-screen zoom menu. A zoom bar shows at the far right side of the screen. All echoes between the top and bottom of the zoom bar are

shown on the left side of the screen. Pressing the up or down arrow keys moves the zoom bar up or down. As you adjust the zoom bar, the range changes on the left side of the screen at the same time.

To return to the full-screen mode, simply press the EXIT key. This also erases the zoom bar and move zoom menu.

GRAYLINE®

GRAYLINE lets you distinguish between strong and weak echoes. It “paints” gray on targets that are stronger than a preset value. This allows you to tell the difference between a hard and soft bottom. For example, a soft, muddy or weedy bottom returns a weaker signal which is shown with a narrow or no gray line. A hard bottom returns a strong signal which causes a wide gray line.

If you have two signals of equal size, one with gray and the other without, then the target with gray is the stronger signal. This helps distinguish weeds from trees on the bottom, or fish from structure.

GRAYLINE is adjustable. Since GRAYLINE shows the difference be- tween strong and weak signals, adjusting the sensitivity may require a different GRAYLINE level, also. The level chosen by the X-65 at power on is usually adequate for most conditions. Experiment with your unit to find the GRAYLINE setting that’s best for you.

To adjust the GRAYLINE level, press the MENU key, then press the up
