3.  3D Display, Overlays

Four chart overlays are available on the chart plotter display. These overlays are 
depth shading, weather, satellite photo, and animation.

The depth shading overlay shows the depths in red (shallow), yellow (medium) and 
green (deep). This overlay is available in both 2D and 3D presentations. Use this over-
lay to find depths. Transparency levels can be adjusted so that the chart data is visible 
under the color shading. To show the depth shading overlay, first use the RotoKey to 
select [Overlay] and [Depth Shade]. Push the RotoKey to show or hide the depth 
shading overlay.

The depth shading settings are on the [Chart-General ]menu. Set this menu by follow-
