Protractor Chart Bi-Rola

Information

Product DescriptionThe Bi-Rola Chart Protractor is suitable for general chartwork in the cockpit aboard small craft. It is ideal for lap top plotting and for use with folded and badly creased charts. The plotter does not need to be referred to the compass rose, it has a movable compass rose grid that can be used to lay off a course or bearing, measure distance between any two points, plot position on a chart from a given set of coordinates, or determine coordinates of position on a chart. The edges of the Protractor are graduated in inches and centimeters.
