Bottom Presentation - Humminbird 343c Operation Manual

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.
