Description

Used in a combination of two, our Protractor Triangle provides a straightforward method of plotting and performing chart work. Each triangle is inscribed with black markings. The protractor scale on the triangle can aid in drawing a bearing line on a chart and the 90° angle is helpful when determining lines of position. The protractor triangle is crafted of clear, durable vinylite.
