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.

Bottom Contour Profile with RTS® Window.

Temp/Speed Accessory is optional.

Rocky Bottom

Soft Bottom

The sonar returns from the bottom, structure and fish can be represented as either Inverse (default), WhiteLine®, Structure ID®, or Bottom Black. See Sonar X-Press™ Menu: Bottom View for details on how to set the bottom view.
