UTM MGRS Metric Navigation Protractor

This square coordinate scale protractor delivers field-proven functionality for users working with UTM, MGRS or USNG grid systems on printed topographic maps. Sized at 10 cm × 10 cm and made from durable, transparent plastic, it combines angular measurement (0–360 degrees and 0–6400 mils) with seven integrated linear scales: 1:10,000, 1:24,000 (aligned for 7.5′ USGS topo maps), 1:25,000, 1:50,000, 1:100,000, 1:250,000 and 1:500,000. Larger-scale rulers for 1:50,000 and 1:100,000 reflect typical grid line spacing on regional and national mapping products. All markings are permanently etched — not printed — ensuring long-term legibility and resistance to moisture, abrasion and UV exposure.
