Viewing past echoes using SoundTrac
On the SOUNDTRAC screen, you can use
Northstar’s exclusive SoundTrac feature to
look back and examine past echo data.
To enable SoundTrac:
1. At the main
SOUNDER
screen, press the
cursor pad to the left.
The position marker — a dashed vertical
line — is now displayed.
2. To move back to echoes that were dis-
played within the past few minutes, con-
tinue pressing and holding the cursor pad
to the left.
The
6000i
recalls echoes from the last
3000 pings.
As you move the position marker with the
cursor pad, the marker speed accelerates
to quickly scroll to the desired location.
The lat/lon of the position marker is
displayed at the bottom of the picture,
along with the time elapsed since the ping,
and the distance and bearing from your
present position to the marker (assuming
the navigator is providing position data).
As you move the position marker left and
right, these coordinates change
accordingly.
NOTE:
When you use the position marker on a
split screen (showing either two frequen-
cies, or zoom mode), each half of the
