True-scale History (Only SEAiq Pilot) : When enabled, a recent history of Own-Ship True-scale positions is displayed. You can select between different time intervals and overall duration for the positions.
The positions are only shown if the Own-Ship True-scale is already enabled. You can view True-Scale Status in Own-Ship settings to see if all prerequisites are met.
While in NMEA Playback mode, the vessel trail will be cleared when jumping forward and backward.
