Record and playback
Overview
You can set up the echo sounder to record the unprocessed
transducer signals on the internal harddisk or other recordable
media. This recorded signal may later be injected into the echo
sounder’s processing software as if it arrived directly from the
transceiver.
During this replay, you may experiment with some of the echo
sounder settings.
This feature is useful during training and demonstration. It is
also useful for memorising a particularly interesting observation
at the fishing grounds.
You can also use the built-in History function to record
echogram data.

- Raw data: The unprocessed transceiver data are stored
in standard computer files. These files contain all the
necessary data for reconstruction of the situation during
the real survey. Thus the data include amplitude, phase,
navigation data, annotation input etc. The echo sounder
program reads these files during replay.
- Output data: This is the processed output data;
navigational data, bottom detections, annotations etc
