Compass

You can also preset an azimuth on the compass during the day for use at night. This is useful when you can see your destination (during the day), preset that azimuth on the compass, and then follow the compass at night (or other times of limited visibility, such as fog). To preset an azimuth on the compass, follow these steps:

  1. Using one of the previous methods, use the compass to determine the desired azimuth. (Gunsight method is most accurate)

  2. Once the azimuth is determined, put the compass in the steady hold position and rotate your body until that azimuth is directly under the black index line. (if you used the steady hold position to determine the azimuth, skip to step 3).

  3. Holding the compass steady, rotate the bezel ring until the luminous line is lined up the north seeking arrow on the floating dial. 

  4. The compass is now preset.

  5. To use the preset azimuth, put the compass in the steady hold position. Rotate the body until the north seeking arrow is lined up with the luminous line. Walk forward keeping the north seeking arrow and the luminous line lined up.

 

If you already know the azimuth (or determine an azimuth by the map...more on this later) and visibility is limited (darkness, fog, heavy forest, etc), then you can preset the compass as follows:

 

  1. Rotate the luminous line directly over the black index line. 

  2. If the desired azimuth is LESS THAN 180 degrees, divide that number by 3 (example: if the desired azimuth is 99 degrees magnetic, the dividing that by 3 is 33). Rotate, click-by-click, the bezel in a counterclockwise direction exactly 33 clicks (for our example) as each click of the bezel results in a 3 degree change.

  3. Use the compass as in step 5 above.

  4. If the desired azimuth is MORE THAN 180 Degrees, subtract that number from 360 (example: the desired azimuth is 255 degrees.            (360 - 255 = 105) Then, take the result and divide by 3 (105 / 3 = 35). Rotate, click-by-click, the bezel in a clockwise direction exactly 35 clicks (for our example).

  5. Use the compass as in step 5 above.

 

If the desired azimuth is not exactly divisible by 3, the round off to the nearest number. However, be advised that on lengthy distances, you will be off of your target destination.
