Clear and Durable Construction

This protractor is made from clear acrylic, which offers a perfect combination of strength and transparency. The 1.5mm thickness provides a sturdy feel, ensuring the tool can handle regular use without bending or warping. Its transparent design allows for easy overlaying on maps and charts, ensuring visibility of the details underneath while you work. Whether you’re using it outdoors in the field or in a classroom environment, the clear acrylic ensures that measurements and markings are always visible and easy to read.

Versatile Measurement Features

One of the standout features of this protractor is its dual measurement system, marked in both MILS and metric and imperial romers. This versatility makes it ideal for various applications, from military use to educational purposes. The protractor includes romer scales at 1:25,000, 1:50,000, and 1:63,360, offering precise grid square measurements for navigating maps with different scales. This flexibility makes the protractor suitable for a wide range of map-reading tasks, from orienteering to advanced navigation exercises.

The metre scales are provided at 1:50,000 and 1:63,360, ensuring accurate distance measurements on maps of these scales. Whether you’re converting map distances or plotting points, these scales offer convenience and precision in one tool.

String for Plotting Bearings

To make plotting bearings even more efficient, this protractor comes equipped with a string attachment. The string allows for quick and accurate alignment when plotting angles on maps, helping users determine precise directions. Whether you’re navigating terrain or working on detailed classroom exercises, the attached string streamlines the process, ensuring you can plot bearings with confidence and ease.

Larger 18″/464mm Version for Classroom Use

For those in educational or training environments, we also offer a larger 18″/464mm version of this protractor. Designed specifically for use in navigation training classes, this larger model offers the same great features as the smaller version but on a larger scale, making it easier for instructors to demonstrate concepts to a classroom. The larger size is perfect for working on large maps or for students who need a more prominent visual aid when learning navigational skills.

To enhance its practicality in a classroom setting, the 18″ version comes with magnets, allowing it to be easily attached to dry-wipe boards. This makes it an excellent tool for teaching, as instructors can securely attach the protractor to the board while explaining concepts or plotting maps in front of the class. The magnets ensure the protractor stays in place, offering a hands-free experience that allows for more interactive and dynamic teaching sessions.

Ideal for Navigation and Training

Its versatility makes it suitable for field use, individual study, or classroom instruction. The durable acrylic construction ensures it will withstand the demands of regular use, and the inclusion of MILS, romers, and metre scales offers all the precision needed for accurate measurements.
