Bottom Presentation
As the boat moves, the unit charts the changes in depth on the display to create a profile of the Bottom Contour. The type of bottom can be determined from the return charted on the display. A Hard Bottom such as compacted sediment or flat rock appears as a thinner line across the display. A Soft Bottom such as mud or sand appears as a thicker line across the display. Rocky Bottoms have a broken, random appearance.
NOTE: A sloping bottom will be represented as a thicker line across the display. Also, harder bottoms will be typically displayed with red and softer bottoms will be typically displayed with blue.
The sonar returns from the bottom, structure and fish can be represented as either Structure ID®, or WhiteLine®. See Sonar
Structure ID® represents weak returns in blue and strong returns in red.
WhiteLine® highlights the strongest sonar returns in white resulting in a distinctive outline. This has the benefit of clearly defining the bottom on the display.
