L'Ocean, Breton navigation plotter Polaris

The navigation plotter Rapporteur Breton Polaris (type Jean Cras) from L'Ocean is a high-quality course ruler for navigation on nautical and aeronautical charts. This sturdy course ruler 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 protected laminated labelling is abrasion-resistant, guarantees years of reliable reading and prevents confusion of the course direction. As there are no moving parts, this navigation ruler is practically indestructible. The ruler is packed in a transparent cover with a hanging hole.
