Log Sonar Chart Data
If you have an MMC installed in the unit, the sonar data shown on the
screen can be saved to the MMC. This can be played back at any time
(to play a recorded sonar chart log, see the entry in this section for So-
nar Simulator). If you have a personal computer and Internet access,
visit our web site, www.lowrance.com, and download the free Sonar
Viewer and the emulator for your unit. These programs will allow you
to replay sonar logs on your personal computer.
