A simpler example, and one
you
can
do
at just about any time, is
finding
your car
in
that
ocean of other cars in the shopping
ma
II
parki
ng
lot. Just park your car, step outside and
let your eXplorist compute your position. (Make sure
that
you
have a clear view of the
sky.) Using the
MARK
button,
save
this
position with the name "Car". When
you
are
done shopping, just go outside the mall and create a
GOTO
with the destination "Car".
No
matter where
you
parked, your eXplorist will guide
you
back, simply and easily.
Hikers, mountain bikers and outdoor enthusiasts often need the option of leaving a trail of
breadcrumbs
that
they can follow back to where they started. The eXplorist
has
a feature
called
BackTrack
that
enables
you
to
do just that.
It
was
mentioned earl ier
that
your eXplorist is constantly computing your present position and
that you can
save
your position
by
using the
MARK
button.
Now,
imagine that your eXplorist
automatically saved your computed positions
as
you
moved along the trail. Pretty soon there
would
be
a set of saved positions, like breadcrumbs,
that
represents the trail
you
have taken.
This is exactly what the eXplorist does.
It
saves
the computed positions
as
hidden points of
interest and strings them together to represent your travels. This is called your
Track,
and the
hidden points of interest are your
Track
Log.
Your
eXplorist enables
you
to
use
this Track, reverse
it
and navigate
you
along the same path
that
you followed to get you back to your destination.
You
might drive to the ranger station and follow the trail
that
leads you to the waterfalls
you have been wanting to see. With your eXplorist turned
on
and able to compute, posi-
tion fixes,
you
continue along the trail. The trail winds along and has many smaller
trails attached to it.
As
the day progresses
you
arrive at the falls. When it's time to
head back to your car,
you
access your Track Logs Iist and select the Active
Track
log.
Now,
press MENU, highlight BackTrack and press
ENTER.
Your
eXplorist will now
seamlessly guide you along the path, tracing your footsteps, back to where
you
started.
Another nice feature of Track
Logs,
which
you
may find useful, is
that
you are able to
save the Track
Logs
and recall them at any time.
In
the above example, at the waterfall,
you could save
that
track and
use
it anytime
you
wanted to
go
back.
