Durable and accurate, it's the best quality for the best price

The Professional Protractor Triangle with handle is larger than other navigation triangles on the market, with sides that are 9-1/4 inches (23.50cm) long and a hypotenuse (long side) 13-inches (33.02cm) long.  Its clean, uncluttered design is inscribed with contrast-enhancing colors (red and black) that display both 320mm and 1-80,000 scales. A hole located at the vertex allows the user to convert the protractor into a quadrant to measure altitude or angle. The triangle is constructed of heavy-duty clear 5 mm thick acrylic for durability, with a handle for ease of use. The handle also holds a pencil, and both pencil and pencil sharpener are included.
