For example, we ran a course on
a local lake, (shown at right) from
the boat ramp to a small cove. To
navigate back to the boat ramp
using the plot trail, press the
Menu key twice, select “My Trails”
then select the desired plot trail
and click on the “Naviate” button.
The screen shown a the bottom
of the previous page appears.
Point 1 on the list is the boat ramp.
Click on the “Reverse” button to
reverse the plot trail as shown at
right. Now the last point on the
plot trail (#11) will be the first one
that the unit navigates to. Now
select the “Navigate” button. The
unit returns to the map screen as
shown at the bottom of this page.
As you travel, the unit will show
navigation data to each point on
the plot trail. When you cross the
arrival alarm radius (default is 0.1
mile), the arrival alarm sounds an
alert. Pressing the Exit key clears
the arrival alarm for that point. The
unit will continue to show naviga-
tion data to each point on the trail
until you reach the destination.
