Brunton Classic Compass

Amazon.com Product Description
This classic, analog compass provides all the information that got explorers around perfectly well for hundreds of years, in a snappy, optic green package. It features 2-degree graduations (the series of degree markings on the azimuth ring used for taking bearings) and adjustable declination (the difference in degrees between magnetic north--the direction the magnetic needle on a compass points--and true or geographical north, which is the direction maps are printed toward. It also features 0-35 degree inclination scale (the distance between two points on a map as they relate to the distance between those two points on the earth) and displays this in both inches and millimeters.
