Using these precision marine hand bearing compasses, you can easily obtain quick magnetic bearings on shore or floating objects. Obtain a bearing simply by aligning front and rear sights on an object and reading off bearing. Uses include quick bearing or position set, determination of angular gain or loss on the competition while racing, checking distance offshore, establishing lee-bow set while cruising or racing in currents, drift vectoring and plotting a line of position.
