Beginners Guide To Using A Compass

What is a Compass?

A compass is an instrument used for navigation and orientation that shows direction relative to the geographic cardinal points. It comprises a magnetic needle that aligns itself with the Earth’s magnetic field, pointing toward the Magnetic North Pole. Understanding the basic components and how a compass works is the first step to becoming proficient in its use.

Components of a Compass

Before you start using a compass, it’s crucial to familiarize yourself with its various parts. Here’s a quick rundown:

  • Base Plate: The flat, rectangular part you hold, often with rulers and scales.
  • Magnetic Needle: The free-rotating needle that always points towards Magnetic North.
  • Compass Housing: The circular, rotating section where the needle resides, usually filled with liquid for stability.
  • Direction of Travel Arrow: An arrow on the base plate indicating the direction you’re heading.
  • Orienting Arrow: A fixed arrow inside the compass housing used to align the magnetic needle and set your course.
  • Declination Scale: A scale to adjust for the difference between true north and magnetic north.
  • Ruler/Scale: Often found on the edges of the base plate to measure distances on a map.

How a Compass Works

The Earth has a magnetic field that exits near the geographic North Pole and re-enters near the geographic South Pole. The magnetic needle on your compass aligns itself with this magnetic field, pointing towards the Magnetic North Pole. This simple mechanism is powerful for navigation, allowing you to determine direction wherever you are.

Understanding Cardinal Directions

Cardinal directions are the four main points of a compass: North, East, South, and West. Understanding these directions is foundational to using a compass effectively.

Memorizing the Directions

A simple mnemonic can help you remember the order of the cardinal directions: “Never Eat Soggy Waffles.” This phrase represents the sequence—North, East, South, West.

Adding Intercardinal Directions

In addition to the main cardinal points, it’s helpful to know the intercardinal (or ordinal) directions: Northeast, Southeast, Southwest, and Northwest. These lie halfway between each pair of cardinal directions.

Setting Up Your Compass

Before you begin navigating, you need to set up your compass properly. This includes adjusting for declination and understanding how to hold the compass.

Adjusting for Declination

The Earth’s magnetic north differs slightly from its geographic (true) north. This difference, called declination, varies depending on where you are on the planet.

  • Find Local Declination: Check a reliable source such as a topographic map or an online declination calculator.
  • Adjusting Your Compass: If your compass has a declination adjustment feature, use it to set the correct declination. If not, you’ll need to manually account for this difference when taking readings.

How to Hold Your Compass

Hold your compass flat in your hand, at a level parallel to the ground. Make sure the direction of travel arrow points directly away from you. This position allows the magnetic needle to swing freely and give an accurate reading.

Basic Navigation Techniques

Now that your compass is set up, it’s time to learn some fundamental navigation techniques. These skills will lay the groundwork for more advanced uses.

Taking a Bearing

A bearing is a specific direction or angle from your current position to a distant point. Here’s how to take a bearing:

  1. Point the Direction of Travel Arrow: Aim the arrow at your destination.
  2. Rotate the Compass Housing: Turn the housing until the orienting arrow lines up with the magnetic needle.
  3. Read the Bearing: The number aligned with the direction of travel arrow is your bearing.

Following a Bearing

Once you’ve taken a bearing, follow these steps to navigate:

  1. Align the Orienting Arrow: Ensure the magnetic needle is aligned with the orienting arrow.
  2. Walk in the Bearing’s Direction: Move in the direction the direction of travel arrow points.
  3. Keep Checking: Regularly check to ensure the needle remains aligned with the orienting arrow.

Returning to a Given Point

It’s helpful to know how to return to your starting point. To backtrack:

  1. Take a Reverse Bearing: Subtract 180° from your original bearing (or add 180° if it’s less than 180°).
  2. Align and Walk: Follow the same steps as above, but in the reverse bearing’s direction.

Using a Map and Compass Together

Combining a map with your compass enhances your navigation capabilities significantly. This technique allows you to pinpoint your exact location and chart a course more effectively.

Orienting the Map

To align your map with the terrain:

  1. Lay the Map Flat: Place it on a flat surface.
  2. Set the Compass Bearing: Use the compass to find north.
  3. Rotate the Map: Turn the map until the north on the map aligns with north on the compass.

Finding Your Position

Use the process of resection to pinpoint your location on a map:

  1. Identify Landmarks: Pick two or more well-defined landmarks visible from your location.
  2. Take Bearings: Use your compass to determine the bearings to these landmarks.
  3. Draw Lines: Mark these bearings on your map. Your position is where the lines intersect.

Plotting a Course

To plot a course on a map:

  1. Identify Points: Mark your starting and ending points.
  2. Draw a Line: Connect these points with a straight line.
  3. Measure the Bearing: Place your compass on the line and rotate the housing until it points north.
  4. Read the Bearing: The direction of travel arrow now shows the bearing to follow.

Useful Tips and Troubleshooting

Even with meticulous care, using a compass may occasionally present challenges. Here are some tips and troubleshooting advice to help you navigate more effectively.

Avoid Magnetic Interference

The magnetic needle can be influenced by ferrous metals and electrical devices. Keep your compass away from items like mobile phones, keys, and other magnets to avoid interference.

Double-Check Bearings

Always double-check your bearings to ensure accuracy. Small mistakes can lead to significant deviations over long distances.
