Rock Filtering
Hides rock identification on the chart beneath a given depth.
This helps you to declutter charts in areas where there are many rocks located at depths well
below your vessel draught.
Depth highlight range
Select a range of depths between which Navionics will fill with a different color.
This allows you to highlight a specific range of depths for fishing purposes. The range will only
be as accurate as the underlying chart data, meaning that if the chart only contains 5 meter
intervals for contour lines, the shading will round to the nearest available contour line.
No Depth Highlight Range Depth Highlight Range, 6 m – 12 m
Shallow water highlight
Highlights areas of shallow water.
This allows you to highlight areas of water between 0 and the selected depth (up to
10 meters/30 feet).
No Shallow water highlighted Shallow water highlight, 0 m – 3 m
