There is a common exception to these rules of thumb. Some fishermen
on freshwater lakes (or the ocean) using downriggers like to see them
on the sonar. In many of those cases, you'll see a 50 kHz transducer
frequency in use because the wider cone angle lets them watch the bait.

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