A compass acc. to the Munich Orientation Convention. It divides the horizon into 12 directions, reducing right/left and east/west confusions and making it easy to calculate turn angles also for the ZigZag and the BeeLine navigation acc. to www.volksnav.de/blind.
Its proper for blind people (with VoiceOver activated) and all those who prefer to handle with 12 instead of 360 directions.
The main benefits are a better awareness for directions and angles and a common language for all nations.
