Adjustment Indicator

In AUTOMATIC mode, the LEGEND

1000 SERIES selects the depth range best suited to keep recent sonar returns visible; however, the depth range can be adjusted to optimize the display for viewing the second return.

The display can also be optimized for maximum

display resolution, making

it possible to distinguish fish very close together or close to the bottom.

Optimizing the Depth Range for Sonar Targets When the image of the bottom does not appear close to the bottom of the LCD display, the Legend 1000 Series is not fully optimizing the display to show sonar targets, such as fish, that are very close together. To enhance the ability of the unit to separate sonar targets and to optimize the display for maximum resolution, follow these steps:

Optimized Display

1.Make sure the Legend 1000 Series is operating in Automatic Mode.

2.Push the RANGE knob. An adjustment indicator appears at the lower right corner of the CHART WINDOW.

3.Turn the RANGE knob counterclockwise until the image of bottom is close to the bottom of the LCD display but still shows the area of interest.

Note: As the depth of the water increases, the LEGEND 1000 SERIES changes the depth range to keep the bottom on-screen. The LEGEND 1000 SERIES uses a depth range to keep the bottom contour close to the bottom of the display.

To return the depth range to normal viewing, turn the unit off and back on again using the GAIN knob. This is the only way to reset the depth range to normal viewing.

MODES OF OPERATION / OPTIMIZING THE DISPLAY

Optimized Display showing second return

Optimizing the Depth Range for Second Return To optimize the depth range for viewing the second return, follow these steps.

1.Make sure the LEGEND 1000 SERIES is operating in Automatic.

2.Push the RANGE knob. An adjustment indicator appears at the lower right corner of the CHART WINDOW.

3.Turn the RANGE knob clockwise until the second return is visible on the display.

4.To return the depth range to normal viewing, rotate the RANGE knob counterclockwise until the depth range stops updating.

Note: The second return does not appear at many of the deeper depth ranges. The appearance of the second return depends on depth of the water, water conditions, bottom hardness and the gain setting.

The LEGEND 1000 SERIES operates with this offset depth range until it is returned to the original settings, or the unit is turned off, after which the unit defaults to factory settings.
