Adjusting Color Gain

The Color Gain determines how echoes of different strengths are displayed. Seven colors per palette are available and the echo strengths are divided into seven bands to correspond with each shade of color.

The Color Gain control sets the lower limit for the top color band: All echoes with a signal strength above this value are displayed in the strongest shade/color. All echoes weaker than this value are divided equally between the remaining shades/colors.

Setting a low value produces small band for the strongest color, but a wide signal band for the other colors; setting a high value gives a wide band for the strongest color, but a small signal band for the other colors.

The Fishfinder also provides automatic or manual Color Gain adjustment. Automatic adjustment displays colors based on current conditions, with as many colors as possible, while minimizing noise and clutter. As conditions change the auto-color gain adjusts. You can manually add bias to the auto-color gain settings. If you select manual adjustment, you will need to re-adjust the gain as conditions change.

To adjust the Color Gain:

1.On the Pathfinder Panel, click GAIN.

2.Click the Gain control for the appropriate frequency:

50KHz Color Gain or 200KHz Color Gain.

3.Click the large button to toggle between Auto or Manual Gain.
