Bottom Line
This is an "on/off" switch. Select the box to enable the function. A bottom line can be added to your echogram to enhance the visual bottom detection. It appears as thin line that follows the bottom contour. The line is drawn in the current foreground colour.
Normal
This is an "off" switch. The white line is disabled. The bottom line is drawn in the current foreground colour.
White Line
This is an "on" switch. A white line can be added to your echogram to enhance the visual bottom detection. It appears as thick line in the current background colour (normally white) that follows the bottom contour. This line will not remove information, it will simply "push" the echo information further down in order to make the bottom
easier to see. You can use the white and the bottom lines simultaneously. Select Normal to disable the line.
Hardness
This is an "on" switch. The Hardness Line can be added to your echogram to retrieve additional information. It appears as thick colour coded line that follows the bottom contour. This line does not remove information, it simply "pushes" the echo information further down in order to show you the bottom
reflectivity. You can use the Hardness Line and the Bottom Line functions simultaneously, but each can not be used together with the White Line. To disable the line, select None.
When you study the bottom hardness, you can learn more about the bottom. Certain species are known to prefer specific bottom conditions. With more knowledge, you are better qualified to estimate the possible catch.
