11.10 Measuring distance, range and
bearing
You can measure distance, range and bearing in the radar applica-
tion. Options for doing so are detailed in the table below.
Range rings
Range rings help you gauge the approximate distance between
points at-a-glance. Range rings are centred on your position and
displayed on the screen at pre-set intervals.
The number and spacing of range rings changes to suit the scale
you have set.
To show or hide range rings

you highlight.
