Note: Depth contours for [FISHING] are drawn differently from navigational chart data
(bathymetric chart data). Fishing chart does not have the latest shallow information,
so select [VECTOR] when sailing into/out of port or sailing along a coastline.
9.1.2 How to display depth contour in detail
You can set the level of detail between depth contour lines by the distance between
the contour lines.
1. Press the MENU key to open the main menu.
2. Select [7. COAST LINE SETTING].
3. Select [2. CONTOUR LINE FINE RNG SETTINGS].
4. Select the range which you want to display in detail. The chart display appears in
the selected range and the following window appears.
5. Set the level for detailed contour display watching the chart display. The larger the
setting, the more detailed the contour lines are displayed. However, chart drawing
speed is slowed.
Note: Contour lines may not be affected by the setting, depending on the range.
6. Press the DISP key to close the menu.
