Navigating the Outdoors
Friday, March 20, 2009 at 3:47PM The compass works in mysterious ways - or at least I thought so at one time, it was kinda like magic seeing this little thing know what direction was what. Well, it's really just one little part of the magnificence of our earth that's helping us out with that. What better way to really feel connected to nature than to find your way with the earths' magnetism.
There are two types of Compasses:
- Card Compass that are usually seen in toys or multi-use items and in vehicles. They have a free rotating ball or circle.
- Mountaineering or Orienteering Compass where the needle always points to the North and you have to move the dial to find directions
For navigating on your hiking and backpacking trips the Orienteering Compass is the way to go as you'll get more precise readings and they have a baseplate that is needed for navigating with a map and compass.
Reasons for using a compass:
- tell which direction you are traveling - your heading
- tell which direction an object is from you - its bearing
- keep you following a straight line of travel
- orient a map - aligning a map with the actual land
- triangulation - determining your location with a map
- plan routes - determine directions and distances to travel on a map
Basic information of a compass:
- 4 cardinal points - North South East West
When looking at a compass and telling other people directions, don't think left and right which change depending on location and direction. Instead think of the cardinal points that always mean the same direction. - 4 intercardinal points - direction halfway between cardinal points - Northeast Northwest Southeast Southwest
- 8 secondary intercardinal points - direction halfway between cardinal point and intercardinal point - North-Northeast East-Northeast East-Southeast and so on
These points are good for general sense of direction but for more precise directions the compass face is split into 360 marks called degrees.
No matter the compass, one end of the needle always points North. On our mountaineering compasses, it is almost always the red end, but it's a good idea to test your compass before starting to use it:
- If you are north of the equator, stand facing the sun around lunchtime. Whichever end of the needle points towards the sun is South and the end that points at you is North.
- If you're 'down under' the North end points towards the sun and the South end points at you.
How to read a compass:
- Hold your compass steadily in your hand so the baseplate is level and the direction-of-travel arrow is pointing straight away from you.
- Hold it about halfway between your face and waist in a comfortable arm position with your elbow bent and compass held close to your stomach.
- Look down at the compass and see where the needle points.
- Turn your body while keeping the compass right in front of you.
- Notice that as the compass rotates, the needle stays pointing the same direction.
- Keep turning until the needle points East keeping the direction-of-travel arrow and North mark facing straight in front of you.
- Important: This is a very common mistake! The compass needle is pointing towards East so I must be pointing East, right? No, no, no! To find my direction, I must turn the compass dial until the North mark and the "Orienting Arrow" are lined up with the North end of the needle. Then I can read the heading that is at the Index Pointer spot (the butt of the direction-of-travel arrow). Since the Orienting Arrow is usually two parallel lines on the floor of the compass housing, a good thing to memorize is:
RED IN THE SHED
- Now we know we are really heading West (270 degrees)
Compass Reading Tips:
- Hold the compass level - if the compass is tilted, the needle will touch the clear lid and not move correctly.
- Read the correct end of the needle.
- Use common sense, such as knowing that if you are heading anywhere towards the sun, there's no way you can be heading north, northwest, or northeast.
- RED IN THE SHED!
- Keep the compass away from metal objects - even a knife, flashlight, or keychain can cause a false reading if too close to the compass.
These are just a few basic points about compass reading. A little something to get you interested in taking a compass out for a walk and seeing how our magnetic earth helps us get around.
