## Overview

## Description

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.

Review: Work great for radar plotting - Standard navigation triangles. Work great for radar plotting, chart plotting, etc. A must have tool for any mariner.
Review: Easy peasy - Who knew you need one of these things until you take a class and discover it's something that you really need. You can line up items easily through the clear acrylic because the lines are there and. . . it makes something that once seemed very complicated and uncertain, easy and clear.
