L'Ocean, course ruler & navigation plotter Breton Polaris Micro

The Breton Polaris Micro course ruler & navigation plotter (type Jean Cras) from L'Ocean is a robust, handy plotter for navigation in confined spaces, e.g. in aircraft cockpits or on small yachts. This plotter is a navigation ruler, mooring triangle and 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 two-colour inscription firmly embedded between the plastic discs is abrasion-proof, guarantees years of reliable reading and prevents confusion of the course direction. The course ruler is packed in a transparent cover.
