Square UTM MGRS Coordinate Scale Tool

A practical, field-tested coordinate scale protractor engineered for real-world navigation with UTM, MGRS and USNG grids. Dimensions: 10 cm × 10 cm × 1.5 mm thick; material: impact-resistant transparent plastic with UV-stabilised pigment to prevent marking fade. Angular markings (0–360° and 0–6400 mils) are scribed along the outer rim for unambiguous azimuth reading. Linear rulers are laser-etched for durability and include 1:10,000, 1:24,000 (7.5′ topo), 1:25,000, 1:50,000, 1:100,000, 1:250,000 and 1:500,000 — with extra-length segments for 1:50,000 and 1:100,000 to span typical grid line distances. No branding or decorative elements — pure functional design focused on clarity, consistency and tactile feedback during use.
