L`Ocean, navigation set compass & Breton course ruler Polaris Mariner Air

L`Ocean, navigation set compass Breton course ruler Polaris Marin Air. The curved Mariner navigation compass is made of matt solid brass. The L`Ocean Polaris Marin Air (type Jean Cras) course ruler rapporteur from Breton is a robust, handy, medium-sized plotter for navigating nautical and aeronautical charts. This plotter is a ruler, a triangle and a course triangle in one and combines easy handling with high precision. All you have to do is place the ruler on the course line and you can immediately read off the corresponding angle on the course scale. With this navigation ruler, errors due to unintentional movement of a triangle are a thing of the past! The embedded two-colour inscription is abrasion-resistant, guarantees years of reliable reading and prevents confusion of the course direction. Both products are made in the EU.
