Declination Overview

There is a difference between True North and Magnetic North. Their poles are hundreds of miles/kilometers apart.
Your compass needle points to Magnetic North, while most topographic maps are oriented to True North. The angular difference between these directions is called Declination. For accurate compass readings, you will need to adjust your compass to correct this angular error (declination).
Declination varies significantly from place to place, and even in the same location over time. Therefore, it is important to know the current declination in the area in which you’ll be traveling. One free resource that offers reliable, up-to-date declination information for nearly any location in the world is www.magnetic-declination.com.
Another source of declination information is your topographic map. On U.S. maps, the declination is typically provided near the bottom of the map. The line marked “ ” denotes True North, while the line marked “MN” denotes Magnetic North.
IMPORTANT: Note whether the declination provided is Easterly or Westerly.

Declination Adjustment

To correct for declination, use the enclosed flat screwdriver to turn the small screw on top of the bezel until the red orienting (North) arrow (not the red magnetic needle) moves the correct number of degrees from “N” on the bezel. If the declination is Westerly, rotate the screw counterclockwise; if Easterly, rotate the screw clockwise. In the image above, the declination is set to 5° Westerly. Be sure to use the orienting lines at the bottom of the capsule and not the orienting (North) arrow as reference lines when correcting for declination.

Key Compass Functions

(IMPORTANT: Correct for declination first)

1. Sighting
   a. Hold the compass level, with the mirror at about a 45° angle.b. Use the sighting cross on the cover to align the compass with your target.
   c. While looking into the mirror, turn the bezel to align the Orienting (North) arrow with the red magnetic needle.

2. Taking a bearing on a map
   Bearing: the clockwise angle between two lines, such as the line from True North to True South and the line from your current position to desired location.
   a. Lay either long side of the compass baseplate along the imaginary line connecting two points of interest on your map (e.g. Point A – current location and Point B – desired location). See Figure 1 below.b. Envision an imaginary line running between the “N” and “S” markings on the bezel.
   c. Rotate the bezel until the imaginary “N-to-S” line is exactly parallel to the North-South lines on your map. See Figure 2 above. (NOTE: the “N” on the bezel must correlate to North on the map.)
   d. Read the current bearing at the index line (luminous marking at top of baseplate).

3. Following a bearing from a map
   a. After completing the steps above, remove the compass from the map and hold it in front of you with the baseplate level and index line (luminous marking at top of baseplate) directly in front of you.
   b. Turn your entire body (and compass) until the red magnetic needle is centered inside the red orienting (North) arrow. Then move forward, keeping the red magnetic needle centered inside the orienting (North) arrow.
   c. After navigating around obstacles, realign yourself with the original line of travel. Then reposition the red magnetic needle inside the orienting (North) arrow and continue on.

4. Taking a bearing in the field
   a. Identify a landmark you would like to reach in your nearby surroundings.
   b. Holding the compass level so that the needle moves freely, point your body and the index line (luminous marking at top of baseplate) toward this landmark.
   c. Rotate the bezel until the red magnetic needle is centered within the orienting (North) arrow.
   d. Read the current bearing at the index line.

5. Following a bearing in the field
   a. After taking your bearing in the field, travel in the direction of the index line (luminous marking at top of baseplate) while holding the compass steady.
   b. Make sure to keep the red magnetic needle centered inside the orienting (North) arrow as you travel.
   c. After navigating around obstacles, realign yourself with the original line of travel. Then reposition the red magnetic needle inside the orienting (North) arrow and continue on.

6. Orienting your map to True North
   The following procedure can help you quickly and easily understand how your map relates to your surroundings:
   a. Rotate the bezel until “N” aligns with the index line at the top of the baseplate.
   b. Place one long edge of the baseplate parallel to the left or right edge of your map. The map and compass must be level so the needle can move freely. The index line must point to the North edge of the map, which must be furthest from your body.
   c. Turn your entire body, map, and compass until the red magnetic needle is centered inside the orienting (North) arrow.
   d. Look up. Your map is now oriented to your natural surroundings. Try to locate and match landmarks in the field and on the map.

Using the Clinometer to Measure Height

The clinometer within this compass can help you determine the height of a landmark or other object by following the steps below:

1. Rotate the bezel using the enclosed flat screwdriver so that the declination is set to zero. The orienting  (North) arrow should be aligned with the “N” on the bezel.
2. Rotate the bezel so that “E” on the bezel aligns with the index line (luminous marking at top of baseplate)
3. Fold the sighting mirror to approximately a 45° angle relative to the baseplate.
4. Rotate the baseplate 90° from horizontal to vertical so  that the right edge is on top.
5. Hold the right edge of the baseplate close to your eye and sight along this edge so that the edge points directly from your eye to the target.
6. While sighting, look at the mirror and read the angular measurement of the red clinometer arrow along the curved declination scale. This is the angle between your position and the target.
7. To calculate the height of the target, use the formula below: Height = Distance to Target x Tangent (θ)

One way to determine the distance to the target is use the appropriate scale on the baseplate to measure the distance between your position and the target on your topographic map. To find the tangent of the angle between your position and the target, you can use the conversion table below:

The clinometer is also useful for determining slopes, such as a hiking trail or ski slope, as well as avalanche safety.

Precautions

• Always check to make sure your compass is working properly before heading out.
• Never expose your compass to extreme high or low temperatures or magnetic fields from objects such as mobile phones, speakers, and ferrous materials. These can cause permanent damage to the compass.
