Context
The range setting defines from how "far" you want to detect echoes. In other words, you specify the horizontal or vertical distance from the vessel to the outer edge of the search area.
NoteThe range value selected and shown is by default only used by the active view.
Even though you can choose a large range value, that does not mean that you can detect your targets on the same range. The
range value only defines the range that is shown in the views. Actual target detection will always depend on the operational
environment, such as water temperature, salinity, interference and layers in the water column.
The selected range is divided into identical distances. These are shown as dotted circles. They are referred to as range rings.
