Choosing cursor-location tide stations
You can choose any tide station on the CHART screen by
moving the cursor to that station.
1. At the CHART screen, press the OVERLAY key, then press
the SHOW TIDES key.
2. As you're displaying the CHART screen showing the area
tide stations and STATION COVERAGE bar, press the
CURSOR PAD to move the cursor to select the desired
tide station (you may have to press the OUT key to see the
location of other tide stations).
3. To view the graph, press the GRAPH ON key.
To turn any tide graph off, press the GRAPH OFF key.
To remove all tide stations from the CHART screen, press the
OVERLAY key, then press the HIDE TIDES key.
To return to vessel functions, press the VESSEL key.
You can change the height display units for the tides at the
DISPLAY SETUP screen. You can display tide heights using
the same units as depths on the chart, or set units to be in feet
or meters. For instructions, see "Tide height units" starting on
page 13-5.
With the currents overlay feature, you can display
current-station information right on the CHART screen.
Whether you select a current station that's either near your
vessel or somewhere else on the CHART screen, you can
display a graph of that current during any 24-hour period.
