Developed for professional guides, the Brooks-Range All-in-One Map Tool Pro; contains all scales typically used on topo maps in the US, Alaska, Canada, Europe, New Zealand and Japan. Cartographers designed and monitored production of this unique tool to meet USGS standards for accuracy; it is accurate within 1/50th of an inch--the size of a period at the end of a sentence.
Measuring only 4 x 7 inches, the non-glare, flexible plastic material prevents broken corners or tearing in cold and severe conditions. Ten scales in both km and miles located along the edges for easiest use include: 1:20,000; 1:24,000; 1:25,000; 1:30,750; 1:50,000; 1:62,500; 1:63,360; 1:100,000; 1:125,000 and 1:250,000 (miles only). Ten slope indexes, a compass rose, a UTM (Universal Transverse Mercator) Grid, and three UTM corner readers also included. Detailed instructions included.
