1.3 The Chartplotter Display
The HSB Series Fishfinder Display includes a Chartplotter. The chartplotter
includes a small-scale world map and detailed navigation information is
displayed when a cartographic chart card is installed. A plotter mode is
provided to enable route plotting and tracking at large scales even when a chart
card is not installed A typical chartplotter screen is shown in Figure 1-4
The chartplotter uses position information from a GPS, DGPS or Loran-C
instrument. Once the position fix has been established, your vessel’s position,
if on screen, is shown as a boat shape pointing in the direction of the current
heading (or COG if heading data is not available). If no heading or COG data
is available, the vessel is shown as a circle.
The chartplotter screen includes a status bar that displays chart scale, with
either cursor position, range and bearing or, when the cursor is homed to the
vessel (by pressing
FIND SHIP)
, vessel position, Speed Over Ground (SOG)
and Course Over Ground (COG).
Any waypoints you have placed are displayed (unless you turned them off in
Chart Set Up as described in Chapter 7) and the current route is shown.
Information can be viewed on-screen by positioning the cursor over a
waypoint, current route or chart object. The chartplotter screen can also show
additional information, depending on your currently selected options, set up
selections and data available from other equipment.
An example chart display, in its default configuration, with a chart card
installed, is shown in the following illustration.
Several functions are available to control the display as follows:
• Zoom in/out and Pan the Display
• Offset the Chart or Center the Chart around the Vessel
• Synchronize the Chart and Radar (if radar data is available)
Operation of these functions is described in Chapter 3.
Chartplotter Display Options
Set up options allow you to customize the chart by choosing what is displayed
(including cartographic features), how it is displayed (including language and
units), heading mode and how the chartplotter operates with other HSB units.
You can also view the cursor position and a variety of data from other
equipment (for example, 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.
