1. Luminous Bezel Indicator: Used to mark an azimuth
during day or night.
2. Dial: Displays direction in reference to Magnetic North.
The Dial is divided into two scales;
a. Outer - (black printing) graduated in mils.
• 6400 mils to a circle
• Distance between black marks = 20 mils
• Distance between black numerals = 200 mils
• N=64(6400), e=16(1600), S=32(3200), W=48(4800) mils
b. Inner - (red printing) graduated in degrees
• 360 degrees to a circle
• Distance between red marks = 5 degrees
• Distance between red numerals - 20 degrees
• N-0, E=90, S=180, W=270 degrees
3. Scale Edge - 5-inch ruled scale (120 millimeters).
Graduated at a ratio of 1:50,000. Distance on a
1:50,000-scale map can be measured up to 6000 meters or
3.7 miles. The scale edge is useful for measuring distances,
orienting a map and aligning azimuths.
4. Sight Wire: Used along with the Sight Groove (12) of the
Lens Bracket (10) to set a course of movement over the
ground; or determine an azimuth by sighting on prominent
terrain features while reading the Dial (2) using the Lens (11).
5. Bezel: Contains the Luminous Bezel Indicator (1). Has a
serrated edge and rotates with a distinct clicking action. Each
click moves the Luminous Bezel Indicator 3 degrees.
