Changing The Displayed Range; Radar Range And Chart Scale Synchronization - Raymarine E120W Reference Manual

Chapter 7: Using the Radar

7.8 Changing the displayed range

You can zoom in or out to view your radar picture at varying scales. The scale is
measured from the centre to the top of the window and is displayed in the left-hand
corner of the status bar.
The scale you will need is dependent upon where you are navigating and the level of
detail that you wish to see:
• Short range scales - provide greater detail of radar echoes close to the vessel,
and are most suited for use as you approach coastlines, habors or other vessels in
the area. The shortest range scale available is 1/8 nautical miles (or the equivalent
in the chosen unit).
• Long range scales - provide the best overview of the vessel's relationship to
landmasses, weather fronts and large ship targets in or beyond the field of vision.
The longest range scale available is between 24 and 72 nautical miles (or the equiv-
alent in the chosen unit) depending upon the scanner fitted.

Radar range and chart scale synchronization

The chart application includes an option to synchronize the radar range and chart
scale.
When synchronization is switched on:
• The radar range in all radar windows, changes to match the chart scale.
• 'Sync' is indicated in the top left-hand corner of the chart window.
• If you change the radar range, in any radar window, all synchronized chart views
change scale to match.
• If you change the scale of a synchronized chart window, all radar windows change
range to match.
With a chart window active, set the radar range synchronization:
Radar range synchronization is not available when the chart motion mode is set
Note:
to Autorange.
The range of the radar is adjusted by pressing the RANGE button.
Press IN to decrease the range scale or 'zoom in'.
Press OUT to increase the range scale or 'zooms out.
