Weems & Plath #101 Protractor Triangle with Handle

Often used in a combination of two, our Protractor Triangle with Handle provides a straightforward method of plotting and performing chart work. Each triangle is inscribed with contrast enhancing colors (red & black), plus a handle that holds a pencil, making it convenient and easy to use. 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. When used in pairs, the second triangle acts as an extension, and the pair together are a reliable means to transfer a directional line on a chart with no slippage.

The scale has three die cut triangles for access to mark the map being measured. The inner protractor is marked in degrees and the outer protractor is in mils. (Size 5" x 5") Our coordinate scales offer significant benefits over the standard issue GTA 5-2-12. The tool is printed on 30 mil plastic stock with a protective coating. This makes it about the thickness and stiffness of a credit card. It's 33% thicker than the standard military issue version, so it's less likely to bent or broken when you need to use it. See the photo of the tool bent almost in half with no issues. It is not easy to break or crease the tools, but it is possible. Even then the tool can usually still be used for navigation.
