Creating and Saving a Trail
A trail or plot trail, is a history of the path you have taken. On the
screen, trails are represented by a solid line extending from the back of
the current position arrow.
With the default auto setting, the iFINDER creates a trail by placing a
dot (trail point) on the screen every time you change directions. (The
method used for creating a trail and the trail update rate can be ad-
justed in Advanced Mode. See Sec. 5 for Trail Options.)
In Easy Mode, this unit automatically creates a plot trail when turned
on. The trail is saved in memory when the unit is turned off. The
iFINDER continues recording the same trail until you clear the trail,
which erases the old trail and begins recording a new trail.
NOTE:
The iFINDER can record up to 9,999 points per trail, which can be
adjusted in Advanced Mode. The default setting is a maximum of
2,000 points. When trail length exceeds the maximum setting, the
unit begins recording the trail over itself.
In Advanced Mode, you can save and recall up to 10 different plot
trails, which may be copied to your MMC card.
Caution:
You also have the option of turning off trail recording in Ad-
vance Mode. If the option is left off when you switch modes, you
will not be able to take advantage of the automatic trail creation
feature in Easy Mode.
Displaying a Saved Trail
The trail is automatically displayed in Easy Mode by default. Trail dis-
play can be selectively turned off and on only in Advanced Mode.
Navigating or Backtracking a Trail
There are two methods for following your back trail. The simplest re-
quires no menu commands, but provides no navigation information
during the trip. The other requires only three keystrokes and provides
a full range of navigation data. Try both methods and see which you
prefer. When walking, visual back trailing is often used because it is
better at following each turn on a footpath. At faster speeds, like on a
highway or water, the Navigate Trail command is handy.
Visual Back Trailing
1. On the Map Page, zoom (
ZIN or ZOUT ) so your trail is visible.
2. Begin moving and watch the Map. Walk so your current position ar-
row follows the trail you made.
