By using a Davis Hand Bearing Compass you can easily obtain quick magnetic bearings on shore or on floating objects. Simply align the front and rear sights on an object and read off the bearing. Davis Hand Bearing Compasses are also great to use for determining the angular loss or gain in a competition during racing, checking distance offshore, establishing lee-bow set while cruising or racing in currents, and drift vectoring and plotting a line of position. Choose from a standard or Illuminated Hand Bearing Compass. Both compasses feature a liquid-damped compass card graduated in 5° segments and a large, contoured handle. Lanyard and instructions included. The illuminated compass sports a solid-state LED with a positive push-on switch.
