Topoplastic course ruler Jean Cras Bicolour

Jean Cras Bicolour course ruler produced exclusively by Topoplastic. This navigation plotter enables genuine one-handed navigation - no second triangle or ruler is required and the second hand remains free for drawing or holding. No more confusion of course values due to two different coloured scales, no moving parts - therefore durable, robust and ideally suited for everyday use on board professional ships, yachts or aircraft. Packed in a transparent cover with hanging hole, incl. description (French) and instruction sketch.
