Transparency

Transparency controls "see through" behavior of the radar overlay. The option "Opaque" superimposes radar echoes
on the chart display without modifying their color. "25%" displays radar echoes somewhat faintly, and "75%"
displays radar echoes very faintly. It is recommended to use 25% or 50% when navigating narrow channels, so as
not to conceal landmasses.
