position will be at a future time, based on your current COG
and SOG. You can set this time to predict your position in one
minute, two minutes, three minutes, five minutes, or 30
minutes, or turn the line off completely; see “Changing the
chart setup” starting on page 13-24.
Range rings
Range rings are two sets of fine black circles that surround
your vessel, which is at the center. The radius of the inner ring
is shown in a small box in the lower left-hand corner of the
screen. Because the range rings surround your vessel, they
help you find your position on the
CHART
screen. For details
about range rings, see “Range rings” starting on page 13-34. To
see an example of range rings on the
CHART
screen, refer to
the sample display screen on page 1-22. On the
DISPLAY
SETUP
screen, you can set the distance units to statute miles
(mi), nautical miles (nm), or kilometers (km).
Water depths
The small box in the lower left-hand corner shows how water
depths (spot soundings) are shown on the currently displayed
chart—in feet, meters, or fathoms. These are the numbers from
the paper version of the chart; accordingly, you can’t change
these units of measurements.
Chart scale
The small box in the lower left-hand corner of the
CHART
screen shows the chart magnification. As you zoom out, this
number changes to
1/2, 1/4
,
1/8
, and so on. As you zoom in, it
changes to
2/1
,
4/1
, etc. The chart scale (such as 1:40000) is
also shown in the box.
