Metal Lensatic Compass

Finding real position on map with compass: Take two azimuth bearings on separate characteristic points visible on the terrain and indicated on the map. Then on your oriented map, take the angle degree reading according to (a), and then draw two rays from each reading your present location is where the two rays intersect.

Lay map down on flat surface, and then align north indicating line on map with magnetic north on compass. The map is now oriented.

(a) When taking the azimuth reading, set sight on object through slot and wire. Then read degree scale though lens. A magnetic azimuth of any object is a compass reading of a directional line across the center of the compass to the object.

The line on the glass bezel is for quick walking through rough terrain: (on the surface of the glass are two lines, one long and one short. They form an angle of 45 degrees with each other). First, turn your compass to face true north, then rotate the luminous line on your glass bezel to whatever number of degrees you wish to walk. Example, move bezel 20 notches till line is on 60 degrees when compass is aligned with North- now you may take a quick reading at any time. While you are walking, just turn your compass towards the magnetic north and walk in the direction of the line on the bezel. Bezel rotates 360 degrees and is marked in 3-degree notches for easy computation (The glass dial, when turned, may produces a scratching sound. Each sound denotes the rotation by 3 degrees).
