A quadrant is an instrument that is used to measure angles up to 90°. This Mariner's quadrant is a simple instrument that enables navigators to measure altitude. An object is observed along the sights and the weighted line gives the altitude above the horizon in degrees along the curved edge. Made in Germany.
