With this navigation ruler, errors due to unintentional displacement of a triangle are a thing of the past!

The protected two-colour laminated inscription 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.
