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. A display of
1/1
indi-
cates the largest magnification at which you can display the
current chart. As you zoom out, this number changes to
1/2
,
1/
4
,
1/8
, and so on. The chart scale (such as 1:80000) is also
shown in the box.
•
To show a more detailed view of your position on the
chart, press the
IN
key located in the lower right-hand
corner of the 961: The chart will be magnified.
•
For a less detailed view of the chart, press the
OUT
key:
The displayed chart will cover a larger area.
The zoom number in the chart-scale box changes with each
press of the
IN
or
OUT
key.
Distance scale bar
On the left-hand side of the
CHART
screen is a vertical ruler
with alternating red and blue sections. The primary purpose of
the ruler is to provide an approximate scale of distances on the
CHART
screen. These distance units are marked on the ruler.
You can set the distance units to statute miles (mi), nautical
miles (nm), or kilometers (km).
DGPS indicator
In the upper left-hand corner of the
CHART
screen is the word
DGPS
, which indicates whether the 961 is receiving DGPS cor-
rections to its GPS signals. If the 961 isn’t receiving corrections,
the
DGPS
indicator won’t appear on the screen.
Differential GPS (DGPS) is a
GPS-system enhancement
that improves accuracy by
receiving additional radio sig-
nals.
