Project A Waypoint - Lowrance 100 Installation And Operation Instructions Manual

Project a Waypoint

You can save a waypoint even if you don't know it's
position or location on the map. This unit lets you project
the location of a waypoint from a known waypoint us-
ing only bearing and distance from the known way-
point. This is useful if you don't know the latitude/longi-
tude of a location, but you do know the distance and
bearing from a saved waypoint or your own position.
(Note: To project a waypoint from your present posi-
tion, you must first save your present position as a
waypoint.)
To use this feature, press the WPT key, then select a
waypoint number that you want to save the projected
waypoint under. Waypoint 5 is used in this example.
Now select "CREATE WPT". Finally, select "PROJECT
POS". The screen shown above appears.
The unit needs a location (reference waypoint) to
project the new waypoint from. The default reference
is waypoint number one. Highlight the "REFERENCE
WPT" label on the Project WPT menu and press the
right arrow key. The screen above right appears. Se-
lect a waypoint using either the waypoint number, or
waypoint list. When you've chosen the waypoint, high-
light the "SET REFERENCE" label and press the right
arrow key. The unit returns to the Project WPT screen
shown at right. The starting waypoint you chose shows
in the middle of this screen. Now set the distance from
the starting waypoint to the projected waypoint by high-
lighting the "SET DISTANCE" label and pressing the
right arrow key. Use the arrow keys to set the distance,
then press the ENT key when you're finished. The unit
returns to the Project WPT screen. Now enter the bear-
ing from the starting waypoint to the projected way-
point by selecting "SET BEARING" from the Project
WPT screen. Once you've entered the bearing, the unit
returns to the Project WPT screen with the distance
and bearing showing at the bottom of the screen, as
shown at right. In this example, a distance of 10.5 miles
and a bearing of 164° was used. Now press the ENT
key. The unit saves the projected location under the
waypoint number that you picked at the beginning.
