200-2916 Compass USGS Magnetic Declination Map for the United States (1995)

The 200-2916 Compass is a rugged liquid-filled siting compass. It is housed in a sturdy plastic case and has a jewelled pivot for smooth operation and luminous letters for easy reading. A sighting slot, wire hairline, and lens are built-in for precise orientation.

The 200-2916 is used to align various wind direction sensors to true North. Orientation of the wind sensor is done after the weather station is set up. True North is usually found by reading a magnetic compass and applying the correction for magnetic declination, where magnetc declination is the number of degrees between True North and Magnetic North.
