1.2 The Pathfinder Radar Display
When a scanner is connected and the radar is in Transmit mode, the radar
picture provides a map-like representation of the area in which the radar is
operating. Typically, your ship’s position is at the centre of the display, and its
dead ahead bearing is indicated by a vertical heading line, known as the Ship’s
Heading Marker (SHM).
The radar picture can be viewed with a variety of fixed or customised range
scales. A status bar at the top of the radar image displays range, current
heading and mode indicators for the various options you can set.
An example radar picture is shown in
Figure 1-2 , with example radar returns
(echoes) and default Pathfinder Radar information. The Status Bar indicator is
also illustrated.
The radar display can show additional information, depending on your
currently selected options, set up selections and the data available from other
equipment. The example displays on the following pages show some of these
features.
Functions are available to control the display as follows:
• Zoom the Display
• Offset your vessel from the centre of the radar picture
Operation of these functions is described in Chapter 2 .
Pathfinder Radar Options
Set up options allow you to customise the radar image by choosing what is
displayed, how it is displayed (including language and units) and heading
mode. You can also view the cursor position and a variety of data from other
equipment, e.g. speed, heading, depth, wind and tide information in a set of
user-selectable data boxes. The cursor box and user-selected data boxes can be
moved around the screen and they can be turned on or off.
Display options are provided in System Set Up and Radar Set Up as described
in
Chapter 7:Setting Up the System Defaults . In addition, Screen Presentation
Options, described in Chapter 2:Getting Started & Adjusting the Display are
provided to switch:
• Cursor Box and Databoxes On/Off
• Range Rings On/Off
• Waypoint Display On/Off
Note: When you switch the display off and on again, these settings are re-
tained in memory.
