Basic Compass Directions (using True North)

When you need to take your bearings relative to True North (not Magnetic North), this is how you do that if you have a compass outfitted with a Fixed Declination Scale. These specific examples are shown using a Treknor T580 Deluxe Orienteering Compass.

What direction is that object ahead?

  • How to use a compass - Step 1

    STEP 1

    Hold the compass level, and directly in front of you, with the direction of travel arrow (The Treknor logo on the T580) pointing to the object ahead.

  • STEP 2

    Pretend your declination is -4 or 4 degrees Westerly. Rotate the bezel until the North end of the needle (usually Red) is pointing to your declination value on the declination scale (the small red scale inside the capsule, on this example).

  • STEP 3

    Now you can read your direction of travel to the object by reading the location where the bezel crosses the reading line inside the bezel (239 degrees in this example).

I know my desired direction. How do I go there?

    STEP 1

    Rotate the bezel on your compass until the reading line is at your desired direction. (In this case, pretend you want to head at a bearing of 55 degrees).

  • STEP 2

    While holding the compass level, and directly in front of you, rotate your body with the compass until the North end of the needle (usually Red) is pointing to your declination value on the small red declination scale. (assuming your declination value is -4 or 4 degrees Westerly).

    STEP 3

    Now the direction of travel arrow (the Treknor logo on the T580 Orienteer Compass) is pointing in the direction you need to go.

Special Traveling Notes: Once you are pointed in the right direction, do not try to walk while keeping your compass lined up perfectly. You will never be able to walk straight enough. Instead, while you are still stationary, pick an object in the distance directly in line with your desired direction -- and walk to that object. After you reach that object, repeat the process to your next object. Keep repeating this process until you reach your required distance or destination.
