- Professional navigation tool: The MP-4 coordinate scale is a grid protractor designed for topographic map reading and land navigation tasks. Its markings allow you to accurately measure distances, plot coordinates, and determine directions on maps. The transparent design provides clear visibility of the underlying map details while you work with the scale. Suitable for staff, hikers, surveyors, and outdoor enthusiasts who rely on accurate map measurements for navigation and route planning. - Clear measurement markings: The coordinate scale includes precise grid lines and angle measurements for topographic maps. Each mark is clearly visible on the transparent plastic plate, making measurements easy to read in field conditions. The 10 x 10 cm size offers ample coverage for most card work while remaining compact for field kits. The protractor includes multiple measuring scales to accommodate different map types and coordinate systems for complete versatility. - Lightweight and portable design: With a 10 x 10 cm size, this MP-4 coordinate scale is built for field use and easy transport. Its slim profile fits neatly in map sleeves, tactical pockets, or navigation kits without adding significant weight or bulk. The clear plastic construction keeps it lightweight yet durable for outdoor applications. Take this survey ruler on expeditions, training exercises, or whenever precise map measurements are required in the field. - Versatile map applications: This coordinate scale serves multiple functions for land navigation and map reading. Use it as a protractor for measuring angles, as a ruler to determine distances with map scales, or as a grid tool for drawing and reading coordinates. The multipurpose design supports navigation, orientation competitions, wilderness exploration, search and rescue operations, and educational purposes where topographic map skills are taught or practiced. Examples of use include field navigation and route planning, surveying and map reading during expeditions or training, and classroom or outdoor education activities.
