Simrad SN90 Operator Manual
Note
The 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.
