Garmin GPS 38 - Manual (Page 18)

The middle of the Compass Page features a rotating “com-
pass” that shows your current heading while you’re moving ,
with a pointer arrow to the destination displayed in the center.
The arrow shows the direction of your destination from the
d i rection you are moving. If the arrow points up, you are
going directly to the waypoint. If the arrow points any other
d i rection than up (left, right, down, etc.), turn toward the
a rrow until it points up and then continue in that dire c t i o n .
The bottom of the Compass Page displays your curre n t
track (TRK) and speed (SPD) over the ground, while the CDI
(course deviation indicator) scale shows how far you are off
course. The diamond in the center of the CDI scale re p re s e n t s
your present position, while the d-bar (the moving vert i c a l
line on the scale) indicates the direction and distance you are
o ff the desired straight line course.
The default setting of the CDI scale is +/- 0.25 miles, with
each mark re p resenting 0.05 miles of course deviation. If you
do get off course by more than the selected scale, an arro w
p rompt will appear at the end of the scale to indicate the
d i rection you are off course. For more information on setting
the CDI scale, see page 47.
When you are one minute away from the destination
(based on your current speed and track over the ground), the
GPS 38 will alert you with a flashing on-screen message box.
To view a message:
1. Press the P key when the message box appears.
2. Press P again to return to the previous page.
When the DST field displays a distance of 0.00 miles,
you’ve reached your destination!
