Trigger Check

Synchronisation of the Source and Seismic Recorder is a common problem on OBC and TZ Surveys. The Triggercheck system utilises a highly accurate PC-based timing card to record the time of an external trigger. The system also decodes information from a header string to record the shot time alongside the line and shot number. The system can record this information autonomously for long periods of time.
