to make a new route with a past echo position as its first
waypoint
•
to add a past echo position to the end of an already dis-
played route
Going to a past echo position is described below. The other
options are described in the Northstar 961/962 Operations and
Reference Manual and the Northstar 957 Operator's Manual or
Northstar 958 Operator's Manual.
To go directly to a past echo position (as long as the GPS is
providing position data):
1. On the SOUNDTRAC screen, press the CURSOR PAD left
or right to move the position marker to the desired posi-
tion, then press GO TO .
The SELECTED CURSOR POSITION window appears.
2. Press GO NOW .
The navigator creates a new temporary waypoint called
COORD and returns to the SOUNDTRAC screen. The
COORD waypoint isn't stored in the waypoint database;
instead, it's placed in the trip, where it replaces any future
trip points. To see this current waypoint on the CHART
screen, press CHART at any time. Your present vessel
position and time have now become a past trip point.
