View Range function
Use
View Range
to expand the range shown in the relevant views to any percentage of
the original
Range
setting. The expansion is made without resizing the echoes using a
"zoom" effect.
How to open
This function is opened from the
Display
menu.
Description
The
Range
function allows you to specify the maximum distance from the transducer to the
outer edge of the sonar beam. By default, the range shown in each relevant view is adjusted
to the chosen
Range
setting. For example, if you set the range to 500 metres, the outer
range of the view is also limited to 500 m.
In some situations you may wish to expand the range in the sonar presentations. Use
View
Range
to expand the range shown in the relevant views to any percentage of the original
Range
setting. When you define a value for
View Range
the presentation will shift to the new
range, while the range defined by the
Range
setting is identified with a thicker circle.
Tip
This function can be used if you wish to move your ship symbol to the bottom of the view.
You can then expand the range without adding zoom.
If you increase the tilt, and then exceed the range using the
View Range
function,
Coverage
Plot
will indicate the current practical range with a circle. The same applies if you set
Range Projection
to True.
