Liquid filled for fast readability with sturdy plastic case. Features a jeweled pivot and luminous letters.
How to Use a Lensatic Compass:
- Take two azimuth* bearing on separate characteristic points (A and B) visible on the terrain and indicated on the map.
- On your oriented map, take the angle degree reading according to point (A) and draw 2 rays from each of points (A) and (B) according to the angle reading.
- Where the 2 rays intersect will be your present location.
A Magnetic Azimuth:
A magnetic azimuth of any object is the compass reading of a direct line across the center of the compass to the object. When taking the azimuth reading, set sight on the object through the slot and wire of the lensatic compass, and then read the degree scale through the lens.
