Marking and Saving Waypoints
Knowing your present position is only part of any
navigation equation. You also need to keep track of
where you’ve been and where you are going.
Waypoints serve as electronic markers that let you keep
track of starting points, destinations, navaids and any
other important position.
The GPS 125 Sounder allows you to mark, store
and use up to 250 waypoints. A waypoint position can
be entered by taking an instant electronic fix, by manu-
ally entering coordinates, or by entering range and
bearing in reference to an existing waypoint. If you try
to mark a waypoint without having a position fix,
you’ll be notified with a ‘No GPS Position’ message.
To mark your present position:
1. Press the
M
key to capture your position.
The mark position page will appear, showing the
captured position and a default 3-digit waypoint name.
To change the default position name:
1. Press the
D
key once to move the field highlight
from the ‘SAVE?’ field to the name field.
2. Press
F
to clear any existing data and begin entry
of the name.
3. Use the arrow keypad to enter the name.
4. Press
F
to confirm the waypoint name. The field
highlight will move to the “comment” field.
If you’d like to add this waypoint to a route:
1. Press
D
once to highlight the route field and press
the
F
key.
2. Use the
U
or
D
keys to enter a route number
and press
F
.
3. Press the
F
key again to save the waypoint.
If you do not want to add this waypoint to a
route:
1. Highlight the ‘SAVE?’ field and press the
F
key.

The GPS 125 Sounder will
automatically name new
waypoints with a default
three-digit name, with the
current digital depth as the
default comment. You may
then highlight either field,
press ENTER, and enter
your own name or
comment.
