Trigger Events are similar to Time-Based Events, but instead of being placed by the time of an Event, they’re placed by the position of an Event.
The most common use for Trigger Events is to create impromptu AGM points along the line during a run. Therefore, Trigger Events may also (optionally) be inserted as rows in the tracking sheet during a live run.
Use Case: You arrive at an AGM location and discover that it has become inaccessible due to flooding or a locked gate. Trigger Events allow you to place an AGM on the pipeline at the fenceline and record an AGM passage at this new location, inserting it into the tracking sheet as a new, impromptu passage.
