A device for a mobile radar apparatus connected to a gyro compass for indicating the true course on a radar screen, where pulses from the radar and the gyro are counted, and upon a pulse signal representing the straight-ahead-position of the radar antenna the counting of the gyro pulses are read into the radar pulse counter which continues counting until a set reference pulse number, upon which a pulse train is released for indication of the desired bearing line on the radar screen.
